There are a few things which I think you forgot to mention: 1. Because of the circular shape of the NXT motor, a J-beam fits very snugly around the end of the motor, and I often use this because it is easier to fix the motors at an angle this way. 2. The price, of course. NXT motors are a lot cheaper than EV3 motors, although prices vary by region. 3. Another minor difference is that you might notice on slightly more used NXT motors is that their shafts tend to wobble a tiny bit. Nothing major, but it may cause problems where accuracy is of the utmost priority. This can be easily fixed by fixing to beams on either side of the shaft with the help of the peg holes on the motor. Otherwise, great video, keep up the good work :D
Great video! Thank you for making a video like this, all of my questions have finally been answered. Most other videos didn't explain as well as this one. Again, thank you!
Loved the video. The only thing I think you missed, perhaps by intent, is price. For a pure engineer price may not be an issue, but for most ordinary folks it is. At the moment I have one EV3 brick which powers four NXT motors, why? Simply because the NXT motors are so much cheaper when buying them second hand. I bought those motors for 7 euro a piece. So 28 euro in total for the motors. Had I bought EV3 motors I would have been able to buy just one for that amount of money. I don't think that the benefits of the EV3 motor justifies the current market price difference. Of course prices vary, while the basic properties you discussed remain constant. Which is probably the reason you left the price undiscussed.
Due to its "Form Factor", the EV3 Large Motor cannot directly drive the common "Wheel 61.6mm D. x 13.6mm Motorcycle, with Black Tire 81.6 x 14.2 Motorcycle Z Racing Tread (2903 / 6596)" combination like the NXT motor can. Instead, the EV3 Large Motor must utilize the larger (and rarer) "Wheel Technic Street Bike (8420) with Black Tire Technic Street Bike (8420) - Narrow, Front (51378 / 51380)" combination.
Yup, when i was younger my mentor made me use nxt motors for competitions and i was like, why? We have EV3 motors after all! Now i know that they are stronger.
This is true, and I have explored this in more recent tutorials. The purpose of the extra sensor is to have a consistent way of measuring speed for both, because it allows me to use the same instrument to measure the speed of both motors (to get the best comparison).
This video was very helpful, thanks!! I use your tutorials every now and then and they are always helpful and they work. Could you make a tutorial on how to make an rpm program for an ev3 L motor using the built in encoders? I have made one that works but glitches out when displaying the data, it seems to forget to reset some digits to zero but when I have it plugged in and debugging it shows all the data fine. I think it is a bug on the p brick, I'm not sure.
he said nxt motors have higher driving/walking torque, but on the chart it said that ev3 motors had higher driving/walking torque, so he said that wrong. but pull torque, or whatever the other torque was, was better with NXT.
The rechargeable batteries are not compatible and they are very expensive If you want to use the NXT battery in the EV3, there is a solution, but it will no longer be usable in the NXT. The charger is the same. The tutorial is here: ruclips.net/video/-v08-6jZXGo/видео.html
Thanks for sharing! I already knew the core was the same, and I figured that they changed the gearing a bit to fit into the slightly different-shaped housing.

I still don’t get it wich motor is stronger next motor or ev3 motor
This was great! I'm definitely suggesting my friends watch this! It was really helpful!
You perfectly answered my questions about the differences. Thanks!

Thanks for sharing this information! That's exactly why I have left price out; the price of NXT motors as I have found, varies wildly.
This video was very helpful! I have always wondered at the finer differences between them. Thanks a heap!
do you have a 4 motor on 2 wheel, 2 eye ev3 program?
what is that sensor?the one you used to count the moter rotation?
HiTechnic Angle Sensor (hitechnic.com).
The motors have a rotation sensor included. No need to use an extra sensor to measure the speed...
@@thomasl.4081 it is not counting the rotations per minute though

Thanks for sharing! That was my reasoning behind using the NXT motors for Sirius 1.2.
I wish they weren't so awkwardly shaped, they're such a pain to build with compared to other motors
I agree... just wait until you see the motors that come with the new MINDSTORMS Robot Inventor!
Hi! I have a NXT but not The EV3....HOW CAN I MAKE IT RUN??? Which pins makes it run?
Great video! one question though: where'd you get that cool rpm sensor?
That is a HiTechnic Angle sensor. I am not sure if they are still available.
could u make a video for making a box robot or linear motor
can you do a video of a very fast car out of a ev3 home edition set
i use an ev3 but with an
nxt motor

i love ur channel it helps me a lot

I'll look into it.
Great video!
I always thought EV3 large motors were more powerful in torque.
he said nxt motors have higher driving/walking torque, but on the chart it said that ev3 motors had higher driving/walking torque, so he said that wrong. but pull torque, or whatever the other torque was, was better with NXT.
I'm waiting for a video about the sensors!!!!!
As far as I'm concerned, the NXT/EV3 sensors aren't worth comparing, as they are not interchangeable.
The rechargeable batteries are not compatible and they are very expensive If you want to use the NXT battery in the EV3, there is a solution, but it will no longer be usable in the NXT. The charger is the same. The tutorial is here: ruclips.net/video/-v08-6jZXGo/видео.html
The nxt motor is an SERVO motor
They are both servo motors.
Thank you!
for my parents pf xl are already not happy
EV3 motor wins!!!
wtf nxt motors win 2-0
I had e dead one of each motor and the torque speed difference is do to a slite difference in gearing the "core" is the same
PS I took the 2 dead units apart
Thanks for sharing! I already knew the core was the same, and I figured that they changed the gearing a bit to fit into the slightly different-shaped housing.
Builder dude your voice has changed a lot since your introduction video
nxt is heavier than ev3
The ev3 motors are more broakable
