Product Detail

Product Tags


This motor is a 35mm diameter high torque decelerating stepping motor with a body height of 35.8mm. The output shaft of the motor can be customized to install gears and synchronous pulleys. After the stepping motor is equipped with a gearbox, the step angle is further subdivided to increase the load torque and control more accurately
Conventional gear reduction ratios include 3.7, 3.82, 5.2, 5.36, 13.7, 14.62, 19.2, 20.51, 26.85, 28.77, 51, 71100139. Suitable gear reduction ratios can be recommended according to customer needs,
The output part of the motor is usually a connecting line, or a customized socket
The mission of the motor is more than 10,000 hours, and the life of the gear is more than 2000 hours.
