[0002] The reduction motor is suitable for realizing the function of deceleration and torque increase. The three-in-one direct-angle reduction motor is composed of three parts: motor, electromagnetic brake and gear reduction box. The right-angle shaft assembly refers to a gear reduction box with an input shaft and an output shaft perpendicular to each other, and the transmission is realized through bevel gears inside. The three-in-one direct-angle reduction motor is equipped with an electromagnetic brake at the tail of the motor.
