Madonna Akins –
Wow, this motor is awesome! I’m building a little robot and this thing gives it plenty of power. The encoder is spot on and works to keep my robot on track.🤝🤝
Phil Stewart –
Motor used to drive a re-spooler, opting for the 100rpm, 12v version because of its higher torque specification. I’m very happy with this purchase, especially after replacing a previous motor that couldn’t meet the required torque.The quality of the motor appears to be very good and the specifications match what was advertised.
