Customers are satisfied with the torque of the electric motor. They mention that it works well, and has stood up to testing so far. Some say that it performs well when used with a pulse wave modulator and power supply. The motor starts up and runs fine every time, and it works great with pwm motor controller. Overall, most are happy with their purchase and recommend it to others.

I will be using this 12vdc 5RPM with a concentric shaft (not the offset shaft), for a pool water solar heater unit on a gimbal that will track the sun. The gimbal will be virtually frictionless on bearings but fairly heavy. Purchased this motor as a test and am VERY happy with its power and construction. Hopefully the output gear and shaft are bonded fairly well (did not check). Greartisan specs 10 kgcm which translates to 0.72 ft-lbs btw, and 0.16A but no load shows 0.062A @12.0vdc with the rotation being CW with labeled polarity, and reverse polarity works fine and CCW. I wish ALL sellers would actually provide ALL the information, and in that I have provided photos of the internals.
Thank you for your feedback
