This is now one of my favorite channels. You give the kind of details I like on everything. I watch all of each video to the end every time. Have a good day sir.
Best robotics series on YT! Thank you.🙏 Especially appreciate your RPi controller & Python instructions. Now, I understand why you don't use stepper motors. Okay, so I'm playing catch-up, but only 2 years behind. Best regards, stay safe, & keep up the good work!😎
I have learned how to use the ODrive controller. I will use it for the future robotic arm with brushless motors. If you don't want to miss it subscribe to my channel.
Very helpful. A video showing how to set up and configure O-drive using the AS5047P absolute encoder (through the SPI connection) with Windows and position, torque, velocity control through Arduino. Happy to make a donation to support such a video.
thank you so much for this! i asked if you'd make a simple tutorial for setting odrive up on a Rpi or arduino a long while ago, and i've only just found this video!!! it's been such a help i've already ordered an odrive and motor and encoder and i've not even got to the arduino bit! thank you so so much. no i can have a good play once i follow your steps :) cheers Julian
Thank you for the first clear video to show how to set up the ODrive! Looking forward to setting this up. Do you think you will do a video on using the ODrive with hoverboard wheels?
This is very helpful. Thanks for taking the time to make this video. I am looking forward to making a type of robotic arm and you videos look like they will be quite helpful. Thanks!
I do not want to upset you, but you are mistaken. Stepper motors work differently. The passport shows the torque holding the load in the locked position. With increasing speed, the torque drops. At 1200 RPM, the moment is much less than 60 RPM and the drop depends on the inductance of the windings. Thank you for the video!
can you provide me the link for the power supply and braking resistor. I'm using same motor, and drive for my project. Thank you If anyone have any idea about it as well can comment it as well.
This would be helpful! As well as vendors... Is it too risky to buy Odrive from Alibaba or banggood?

on the website of odrive, they have removed the usb permission code, which I consider very important since without that it does not recognize you that the odrive is connected. I was looking for that code on the internet, so I share, I will write to the odrive because they removed that important code. echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="1209", ATTR{idProduct}=="0d[0-9][0-9]", MODE="0666"' | sudo tee /etc/udev/rules.d/50-odrive.rules sudo udevadm control --reload-rules sudo udevadm trigger
it would be great to consider costs, as well as what larger motors and clearpath motors. With some suggestions of drawbacks

hi, the ODrive controllers (129USD) is only one for one brushless motor? and how much is the reduction that you use? do you recommend some reduction link?
Thank you sir for the informations, im trying to build a Ventilator using a Raspberry pi 4, two Brushless motors to drive the air pump and im wondering if your setup would work on my project. Can you please link the Resistor you are using
hello I have a question for you, is there a mistake in the calculations? Because i cant found the same resault with you. For example to odrive d5065 ; i found it 1.72 Nm torque with using your formul that below at the table. can you explain please?
Emrah Elzeren great question. The torque, which I put in table is maximum torque (at low, almost zero rpm). You calculated the torque at max rpm. To calculate maximum torque, at low rpm, you cannot use this formula (below the table).
@@Skyentific Am I correct that you got max torque by choosing 60 Amps instead of max 65 Amps from motor specs? MaxTorque=(60/(2*pi*Kv))* 60amps? How did you then calculate the power value? I have been stuck on this, Thank you
Hi! I am currently working on very similar project, and would like to know the type of connector that is on the end of the cords coming from the o drive motor. Thanks!
Hi! Did you run this or other BLDC at max power? Or at least 1 kwt? Does oDrive allow this? l made a DIY controller and burned some mosfets with a 1.5 kW motor:)

Hi i'm interested into buying the ODrive controller and i have a question: The ODrive site shows a list of some bldc motors and their characteristics. Does the ODrive works with any type of bldc motor or only the ones shown on the previous list?
Hi, i have a problem connecting the raspberry pi, when i run the odrivetool im not been able to recognized and connect the board, i tried ttyUSB0 port, ttyACM0 and its not connecting how did you manage to connect. please help me.
Good question. This driver is build and sold by ODrive Robotics. And the driver is open source, so you can find schematics: github.com/madcowswe/ODriveHardware/blob/master/v3/v3.5docs/schematic_v3.5.pdf. They use mosfets: NTMFS4935NT1G. Good luck with your project.
hi i have dc brushless motor 8 wire from orient japan vexta axhm5100-gfhk2 100w ...2500r/min is there any way to used it on cnc ? if not how can drive it ? thanks
I believe you got the power and torque values from your own testing actually? I think I followed your math backwards. So I assume one cannot entire trust values provided from manufacturers?
This is a gearbox which I bought on Aliexpress around 5 years ago for 400 or 500 dollars. It has flanged output, relatively low backlash, and the gear ratio is 32. It is made for Nema 23 motors. On aliexpress you can find other similar gearboxes, try to search for "flange output planetary gearbox reducer for NEMA23".
I disagree with comparing BLDC motors with stepper motor when only the BLDC has the torque advantage of a reduction gearbox. some of the comparison may hold true, but I walk away from an apples to watermelons comparison. Maybe that's why the channel is called Syyentific?

Kokot mKokot, I know. This make my point even stronger, meaning that the brushless motors more powerful than steppers.
@@Skyentific This is certainly true, but the comparison must be given correctly)
Kokot mKokot But for my application the rough estimation is enough.

What wire thickness did you use?

Nice one. Now, with the gearbox, all your holding-torque problems are gone.
This is true. But this reducer is very expensive... I think I should build something more affordable.
Can this be used for a robot arm?
Yes, of course! And for my next robot arm I would like to use ODrive controllers with the brushless motors.
y go through all this pain isn’t it easier to use a stepper motor?
