Frequently Asked Questions
What voltage range can I use safely with this motor?
The motor is rated at 3 V DC. You can operate it between 2.5 V and 3.5 V for short periods, but best performance and longevity occur at the nominal 3 V.
How do I attach a wheel or pulley to the output shaft?
The gearbox shaft is D-shaped with a 3 mm diameter and 9 mm length. Use a matching bore wheel hub or pulley with a set screw or E-clip to secure it onto the flats of the shaft.
Can I stall this motor without causing damage?
Thanks to its metal gearbox, the motor tolerates occasional stall conditions with high torque output. However, continuous stalling can heat the motor windings—avoid prolonged stalls to maintain performance.
