Love it

Sep 14, 2021

I love these motors on my mbs comp95. Climbs any hill like a candy(well im 70kg hahaha)
Read somewhere comments that they are noisy on big speeds, but so far at 30miles it works like a small east side gang of bees and didn’t experience that big noise that was said. Maybe 30mph still not as fast to hear it.
Overall I’m super happy!!

Great motor for reasonable price

Oct 28, 2019

Used it on my E-scooter for quite some time now(over 500km) and can verify that this is real deal. Running at 53A FOC on 12S battery with modded Vesc 4.12. Annoying thing that at higher speeds motor is quite loud, small bearings... I hope they won't fail soon as this motor is almost non-repairable. Screws will strip before loosening. Cannot use heat to burn loctite off as there is magnets on the rotor outside.

Quality and Price perfect combo

Jul 31, 2019

Great overall motor. Quality/Price it is excellent. Using them on Vesc6+, 55 max amp (At 80amps stator get overload), but increasing the exponential throttle to 30 positive to accelerate and 0.10s positive ramping, make them great for my DIY Hybrid build. Wish they made a version with bigger stator. Very happy with my purchase.

Overall Powerful Motor for good price

Mar 13, 2019

I'm using this Motor now in my Lathe. Because of high max voltage (I use 48V now) and low KV it's a strong BLDC that can push out some power at lower speeds.
Some comments: when I wanted to find out which sensor wire corresponded to which motor wire, I noticed that opening this motor is not a good idea. Most screws will be destroyed before they come loose, they are glued in place. So repairing it yourself if probably not an option. Fortunately I was able to find out the wiring without fully opening the motor.
Works well with VESC in FOC mode. On high speeds it's still a bit loud for my taste, on lower speed it's very quiet. For the rated power, I find it has small bearings, I would have preferred bigger ones, that might also help with the noise on higher speed. But overall it's a very powerful motor in a small package that is a very good fit for my mini lathe.

Awful quality control and shipping

Jun 29, 2018

The package I received was destroyed and there was nothing protecting the motors. The motors look like they’ve been through war. They are also have spots of sticky gunk all over them. I don’t know if that’s from something leaking in the destroyed packaging or if I was sent a return. Cosmetically these “new” motors are a 4 out of 10. 10 being what a new product should look like.
I haven’t hooked them to power yet as I’m hoping someone gets back to me about the damage first.
100% disappointing.
