Notice: Data in this typical specification sheet are for other certain customers. Voltage, rated torque, speed, current, power and shaft extension feature & dimension can be customized to meet customer specific requirement.

Remark:

Gear Motor Torque=Driving motor torque*Reduction ratio*Gearbox efficiency;

Gear Motor Speed=Driving motor speed/Reduction ratio

Motor detailed config can be customized according to customer's requests,
like voltage, speed, as well as shaft length and shape...
