Stepper motor stepper motor under what circumstances use reducer? To look at the now: (1)Stepper motor stator phase current switching frequency, such as change the input pulse stepper motor drive circuit, make its slow movement, stepper motor at low speed when the step by step instructions the rotor in a stop state, when low speed step by step, the speed will shake a lot, at this point as to the high speed, can shake problem processing speed, but lack of torque and that would shake torque at low speed, but lack of high speed and torque. (2)Small (Below 50 mm)Step type PM stepping motor is apart from the Angle of 7. 5°, the electricity opportunities present azimuth change control precision problem. (3)Stepper motor output shaft and the use of direct driving load method, when the load inertia big, will speed up the phenomenon of lack of torque. (4)Expecting the low speed high torque braking. The above situation should consider using the gear reducer, step motor using the reducer, require small backlash, impact resistance, high strength of tooth surface.
