@@corvetteguy50 I keep seeing these great concrete 3D printer projects, but I haven't seen build details anywhere. Considering the small houses they're building are always charity projects, it's a bit odd that there are no printer build instructions in the public domain. Do you see any problems using a NEMA 42 or 34 in a geared rotary-type printer with an aluminum arm that telescopes, say, ten feet from the center? On second thought, now that I've written it out like this, I suppose the math is straightforward. Just the same, have you happen to have seen any information on the internals of those enormous printer builds? Thanks for any guidance.
@@Chocolatchips , Thank you for your support. I believe those printers are strictly proprietary to the manufactures of them. This is of course not to say they can't be replicated, but the engineering is required to be done by the end user of the project. A Nema 42 gear reduced motor would be the only possible solution for such a robot, or custom made motor. Large scale production robots like these take ample amounts of engineering knowledge, and money to accomplish, which discourages many of them. Thank you Vince
In my 18 years of experience in cnc conversions, my opinion is: It's always much better be over than under powered specially when it comes to stepper motors which have no position feedback and missing steps ruins parts!
thank you, very informative I built a 3x3 table with 8080 frame with ball screws, 100 lb gantry. I use NEMA 23s 570 in oz motor. I have seen these motors twist the frame before the motor stalled.
Hey Gary, thank you for your support, and your exactly right. Steppers oz/in per IN/LB are very strong, and most end users really overestimate their requirements . Thank you, Vince
Ran across this video in doing research for a new project. Have some questions, thought I would ask here. Long story short, I am in need of building a rotary table of sorts to polish a telescope mirror. Normally, mirror grinding machines like this are built with ~1hp 3 phase induction motors using a VFD for speed control. The tables can be run anywhere from 0 to 60 RPM and gearing is done via belts/pulleys or reduction gearboxes. Table diameter would be around 18-24 inches and the mirror diameter would be 12-16 inches. Load placed on the table is typically weight of the mirror + polishing tool + 20-50lbs of weight to help with grinding/polishing. Let's assume a load of 75 lbs total max, real world scenario probably isn't even close to this. The load will generally not be on center and will overhang the edge of the table at times. The problem with the 3 phase 1hp motor is that I really don't want something that big so I was thinking of going with a NEMA 34 (1600oz/in) plus a 10:1 reduction NMRV40 worm gearbox as the footprint would be much smaller. So questions are: Is NEMA 34 overkill for this? I'm worried about stalling the motor, skipping steps, not having enough torque, etc... Is a stepper motor even a feasible way forward for this even at NEMA34 size? Would NEMA 23 suffice? I get the feeling no. I have experience with NEMA23 ClearPath steppers on my CNC machine I built, they are quite powerful and perform like a champ on the machine. I've tried to stop the gantry from moving forward using my hands but im pretty sure the earth just rotates underneath rather than the gantry stopping. It's pretty strong. That said, a CNC machine driven by ballscrews and a rotary table with 75lbs of weight on it are completely different applications. Any thoughts or insight would be appreciated.
Stepper motor's run on step, and direction signals for precision control. DC motors in a scooter aren't applicable to precision robotic applications. Thank you, Vince
I'm about to start a Gerber Sabre 408 retrofit. Sounds like you've done a few of those. I'll be working on wood primarily. Any "standard" recommendations on motors for the X, Y, and Z axis. I really find your videos very informative!
Thank you for your support. You'll need to talk to your motor supplier to answer this questions as its based on specific motors torque curve with matched power supply. Thank you, and have a great weekend! Vince
Mr. Santiago thank you for your support. The load your wanting to rotate would require a Nema 42 with at least 2800oz/in motor for maximum stability for that application. Thank you, Vince
Question is can i mill aluminum using my nema23 or it depends on the spindle size what the best spindle to mill aluminum if so thank you for the amazing video
Eclipse, Thank you for your support. A Nema 23 is easily capable of machining aluminum. I designed my 600oz/in Nema 23's for metals, and softer substrates. Here's Nema 23's machining aluminum. ruclips.net/video/LLHbzmXAPps/видео.html Spindle size does matter, but effects your feed rate variable the most as it has to keep up with the motors motion to provide smooth cutting. Think in terms of a Dremel tool which can cut steel, but must move very slow to do it properly, so the tool will actually cut it. A well balanced system is key. A 2.2Kw (3HP) spindle is optimal for optimal feed rates. The motors you use should be as strong as possible in a Nema 23 frame. Thank you, and have a great Labor Day weekend! Vince
corvetteguy50 // so you mean i need to lower the speed of spindle to get accurate cut and more torque as the torque inversely proportional with the rpm .. my last question is if the 800w spindle 1hp is the only spindle available for now is that ok to mill aluminum as a beginning
@@yasirh2004 No you'll need to lower the feed rate of the systems axis, so the spindle can keep up with the cutting required. 800W was used in the video link I sent you in the previous reply. Start with a slow feed rate with proper lubrication on your endmill, and you'll be fine. Thank you, and have a great Labor Day weekend! Vince
corvetteguy50 // never heard of feed rate before but after you told me that I searched for it and i’m totally understand what it means thank you very very very much really appreciate these answers 🙏🏻

Balogun, thank you for your support. A 500+lb. gantry is only the units weight, but it will be mounted on bearings which will be supporting the load, so the actual force required to move the gantry is much less depending on the quality of bearings. Genuine HiWin is the best. I would recommend my Nema 23, or Nema 34 depending on the length of your chassis. Please tell me, and I'll direct you to the motor. Thank you, Vince

No you would require a gear box for acceleration on a chassis that size. I would recommend a Nema 34 do to your chassis length to allow the torque produced from it to allow for higher rapids. Unfortunately their are tom many variables to just recommend one for you without covering the details in your chassis. Please contact me via email to discuss engineering consultation.

Hi, I bought a Nema 23 with a 6.5mm shaft to turn my 150mm rotary table. I can turn the table by turning the 11mm shaft by finger and thumb but the stepper dose not have the torque to turn the table. I then purchased a much bigger Nema 23 with a 10mm shaft but it still won't turn the table. Any help appreciated thanks
Berty, thank you for your support. Who did you purchase the motors from? The vendor you purchased from should have matched their torque to your application pending you explained it to them. Thank you, Vince
Thank you for your support. This can't be calculated without knowing the transmission you're using in conjunction with the motor.

Thank you for your support. You don't need Nema 34 motors for that size chassis. You should be using Nema 23's. I recommend using the motors by themselves with a ball screw transmission. If you need more support please contact me to setup a consultation. Thank you, Vince
@corvetteguy50 Thank you a lot for your reply. I have already bought the stepper motors, and I'm using a gear rack to move the axis along. I choose the nema 34 as they are closed loop motors, and i have found your video too late. I can't send them back now, so i have to use them. Firstly, i taught i need a gear reduction for them as they are really powerful.
I have a nema 23 on my Z axis on my Lathe and when it comes to doing a peck cycle it misses steps needs more torque, if I lower the acceleration will that give me more Torque ?
Thank you for your support. It may help, but usually missed steps are do to EMI, and overdriving the motor out of their operating envelope. Reducing the motors speed would help with this as well. Thank you, and have a Happy safe New Year! Vince

Joshua, You didn't specify if your using a transmission that the motor will rotate to turn the shaft, or if your using direct drive? A 30 lb shaft would require a Nema 34 based on their available torque output. Thank you, Vince
A 30lb shaft which is rotated easily by up to 100in/lbs of torque using the video tutorial above. Your shaft's weight is only 30% of the rotational torque put out by my 1700oz. All Nema 34's put out roughly 80-100in/lbs of torque. Thank you, Vince

For the love of Christ compels us, because we judge thus: that if One died for all, then all died; 15 and He died for all, that those who live should live no longer for themselves, but for Him who died for them and rose again. 16 Therefore, from now on, we regard no one according to the flesh. Even though we have known Christ according to the flesh, yet now we know Him thus no longer. 17 Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 18 Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, 19 that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. 20 Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. 21 For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. 2 Corinthians 5:14-21

Max center weight i would have is 20 lbs. Can you please suggest me a stepper motor, Not sure if i should go with Nema 23 or 34. Also i would be adding an wormgear to the motor.
Varun, Thank you fro your support. Your application would require my Nema 23 600oz motor as it produces 3.5in/lbs of torque. If your adding a a worm gear for gear reduction the motor will produce even more torque, but reduce its available rotational speed. Thank you, Vince
@@corvetteguy50 also, if it is not a lot to ask , what would be the maximum rpm of such motor. Because I want the robot to move at reasonable speed (10-15km\h or even more) and does the motor accelerate fast ?Thanks!
@@ivankolev5279 Steppers aren't designed for speed, their designed for torque. If you want speed incorporate a gear transmission, and you can have it accelerate to high RPM efficiently. Thank you, Vince
I have heard that using smaller motors results in more torque at higher speeds because of lower inductance. Is this true? I look at torque charts and do indeed see how nema 32's drop off quicker than nema 23's, but at 1000 rpm's, the 32 still has more torque. This idea seems to be repeated a lot on CNC forums. Any idea?
Digital, thank you for your support. the thing to keep in mind is steppers are designed for low end torque, and not speed. I see this discussed all over forums. The truth is if you use a stepper with more torque the more it has a buffer to move a load at a higher speed. This is because the motor has an extra surplus of torque available. Inductance is a technical term to say electrical resistance, and forum guys preach this everywhere. You should never be selecting a motor just by its inductance, but rather the transmission its supporting as its what actually provides the speed of the system. Thank you, Vince
Prasad, Thank you for your support I really appreciate it. I need to know what substrate your surface grinding, and the the transmission your machine uses that you intend to do this with to answer your question. Thank you, Vince
Hey bud, this big motor, standing upright, can this turn a 250lb person left or right with no problems? I'm looking to build a motorized platform and connect to a Arduino UNO to control it. I say 250lb as a max load. Thanks for any reply.
Virtual, Thank you for your support. I really appreciate it. The Nema 34 with a gear reduction would be fine for that application as I have a few clients using motion control for simulators. Thank you again, Vince
@@corvetteguy50 Thanks for the quick reply, 1 more question which may be of help, I'm having someone coding to a Arduino to control the motor to my liking, would it be better to use a open loop motor or a closed loop motor for my project. Thanks again, and love the channel
@@Michael-hr5wf , for your application an open loop stepper is fine as they provide the same accuracy as a servo as reflected in this previous video I made here ruclips.net/video/Exk7ORteS0o/видео.html Thank you, Vince
My application is going to be to drive an 16mm diameter extrusion screw as a part of my capstone project and from the calculations I have done it seems that I may need the 34 but do you think diffferently?
Yes, but the length depends on the specific manufacturer. I would contact the particular one your looking at a motor from for exact dimensions. Thank you, and have a great weekend! Please be safe. Vince

@@corvetteguy50 I keep seeing these great concrete 3D printer projects, but I haven't seen build details anywhere. Considering the small houses they're building are always charity projects, it's a bit odd that there are no printer build instructions in the public domain. Do you see any problems using a NEMA 42 or 34 in a geared rotary-type printer with an aluminum arm that telescopes, say, ten feet from the center? On second thought, now that I've written it out like this, I suppose the math is straightforward. Just the same, have you happen to have seen any information on the internals of those enormous printer builds? Thanks for any guidance.
@@Chocolatchips , Thank you for your support. I believe those printers are strictly proprietary to the manufactures of them. This is of course not to say they can't be replicated, but the engineering is required to be done by the end user of the project. A Nema 42 gear reduced motor would be the only possible solution for such a robot, or custom made motor.
Large scale production robots like these take ample amounts of engineering knowledge, and money to accomplish, which discourages many of them.

Ran across this video in doing research for a new project. Have some questions, thought I would ask here.
Long story short, I am in need of building a rotary table of sorts to polish a telescope mirror.
Normally, mirror grinding machines like this are built with ~1hp 3 phase induction motors using a VFD for speed control.
The tables can be run anywhere from 0 to 60 RPM and gearing is done via belts/pulleys or reduction gearboxes.
Table diameter would be around 18-24 inches and the mirror diameter would be 12-16 inches.
Load placed on the table is typically weight of the mirror + polishing tool + 20-50lbs of weight to help with grinding/polishing.
Let's assume a load of 75 lbs total max, real world scenario probably isn't even close to this. The load will generally not be on center and will overhang the edge of the table at times.
The problem with the 3 phase 1hp motor is that I really don't want something that big so I was thinking of going with a NEMA 34 (1600oz/in) plus a 10:1 reduction NMRV40 worm gearbox as the footprint would be much smaller.
So questions are:
Is NEMA 34 overkill for this? I'm worried about stalling the motor, skipping steps, not having enough torque, etc...
Is a stepper motor even a feasible way forward for this even at NEMA34 size?
Would NEMA 23 suffice? I get the feeling no.
I have experience with NEMA23 ClearPath steppers on my CNC machine I built, they are quite powerful and perform like a champ on the machine. I've tried to stop the gantry from moving forward using my hands but im pretty sure the earth just rotates underneath rather than the gantry stopping. It's pretty strong.
That said, a CNC machine driven by ballscrews and a rotary table with 75lbs of weight on it are completely different applications.
Any thoughts or insight would be appreciated.
Thank you for your support.
Please contact me through my videos description to setup a half hour engineering consultation.
Thank you,
Vince
This helped alot , my gantry is about 80 lbs on the 4x8 table, so that 600 oz motor will do what I need to do on this plasma. Thanks Sir!!

Question is can i mill aluminum using my nema23 or it depends on the spindle size what the best spindle to mill aluminum if so thank you for the amazing video
Eclipse, Thank you for your support. A Nema 23 is easily capable of machining aluminum. I designed my 600oz/in Nema 23's for metals, and softer substrates. Here's Nema 23's machining aluminum. ruclips.net/video/LLHbzmXAPps/видео.html
Spindle size does matter, but effects your feed rate variable the most as it has to keep up with the motors motion to provide smooth cutting. Think in terms of a Dremel tool which can cut steel, but must move very slow to do it properly, so the tool will actually cut it.
A well balanced system is key. A 2.2Kw (3HP) spindle is optimal for optimal feed rates. The motors you use should be as strong as possible in a Nema 23 frame.
Thank you, and have a great Labor Day weekend!
Vince
corvetteguy50 // so you mean i need to lower the speed of spindle to get accurate cut and more torque as the torque inversely proportional with the rpm .. my last question is if the 800w spindle 1hp is the only spindle available for now is that ok to mill aluminum as a beginning
@@yasirh2004 No you'll need to lower the feed rate of the systems axis, so the spindle can keep up with the cutting required. 800W was used in the video link I sent you in the previous reply. Start with a slow feed rate with proper lubrication on your endmill, and you'll be fine.

If you drive each y-axis with a separate motor do the torque ratings add linearly. For example 2 x 2nM = 4nM?

How would I increase torque for a stepper motor? Do i buy geared stepper motors?
hi i am thinking of building a epoxy granite plasma cutter 8 x 4 what stepper would u recommend for this project manly worryed about the y axis also so would you use a lead screw or a rack and pinion thanks
Stephen, thank you for your support. A stepper motor for a plasma system is generally no larger that 400oz/in as there's no load on the cutter. I highly recommend a ball screw transmission over a R&P as its much more precise, and virtually maintenance free. Thank you,

how to calculate running torque(normal) from holding torque
Shoaib, thank you for your support. Holding torque is the torque rating that will stall the motor if exceeded. Normal running torque is anything the motor produces under this rating as that's considered usable torque. Thank you,
Vince
it would have been nice with metric system (Nm)
ingDemurtas thank you for your support. Here's a converter to make it simple. www.convertunits.com/from/oz-in/to/N-m Thank you,

Can you easily measure the torque that the motor is producing?
I need to build a test bench to know the max amount of force the product can take / find the breaking point
Hey Brent, Thank you for your support. Unfortunately when it comes to engineering seldom are things easy when dealing with measurement accuracy. There are designs on RUclips, but the accuracy is based on the equipment, and the knowledge of the end user performing the measurements. Thank you,

What stepper motor would work in a sewing machine? I am wanting to swap motors for better control of my speed.
Tina, thank you for your support. I suggest removing, or reviewing the one installed in the machine to know its current size, and ratings so you then would know the size you require to replace it with. You can then get the same size motor with more torque for faster production. Thank you, and please be safe.

If I want a stepper motor to rotate a 30 lb shaft, how do I determine how much torque is required to do so? Can't seem to understand what equation or even what exact variables I need to solve this problem. I need to buy a motor but I want to know exactly what I need so I don't overspend.
Joshua, You didn't specify if your using a transmission that the motor will rotate to turn the shaft, or if your using direct drive? A 30 lb shaft would require a Nema 34 based on their available torque output. Thank you, Vince
corvetteguy50 hey Vince, thanks for your reply. I will be using a direct drive. How did you determine i would need a Nema 34?
A 30lb shaft which is rotated easily by up to 100in/lbs of torque using the video tutorial above. Your shaft's weight is only 30% of the rotational torque put out by my 1700oz. All Nema 34's put out roughly 80-100in/lbs of torque. Thank you,
Vince
Thanks for this vid!
just bought a nema 23 with 8mm shaft, and I'm looking for a reduction gear, even a simple spur gear.
Not only that I found nearly nothing on eBay and aliexpress, but the very few I did find weren't design the 8mm D shaft.
Any recommendations?
Ofir, thank you for your support. The most common solution is to purchase a gear with a bore of 6.35mm, and open it up to 8mm with a drill, or a lathe pending it has enough material available which most do. Thank you,
Vince
1700oz/in means 12n*m so this kind of motor can be used for construction of a electric scooter? What will be a nice battery for it based on your knowledge?

John, thank you for your support. Motor torque has nothing to do with table length. The torque of a motor dictates the machining capacity its able to handle while under load.

I have heard that using smaller motors results in more torque at higher speeds because of lower inductance. Is this true? I look at torque charts and do indeed see how nema 32's drop off quicker than nema 23's, but at 1000 rpm's, the 32 still has more torque. This idea seems to be repeated a lot on CNC forums. Any idea?
Digital, thank you for your support. the thing to keep in mind is steppers are designed for low end torque, and not speed. I see this discussed all over forums. The truth is if you use a stepper with more torque the more it has a buffer to move a load at a higher speed. This is because the motor has an extra surplus of torque available. Inductance is a technical term to say electrical resistance, and forum guys preach this everywhere. You should never be selecting a motor just by its inductance, but rather the transmission its supporting as its what actually provides the speed of the system. Thank you,
