One is the characteristic of overload. Its speed is not affected by the size of the load, unlike ordinary motor, when the load increase would be a drop in speed, stepping motor when using all has the strict request to the speed and position. Second, the control is convenient. Stepper motor is a 'step' as the unit of rotation, the obvious features of digital. 3 it is the whole machine structure is simple. The traditional mechanical speed and position control structure is more complex, adjustment difficulties, using stepper motor, makes the whole machine structure is simple and compact. Speed motor speed is converted into voltage, and passed to the input as a feedback signal. Speed motor is a kind of auxiliary type, installed at the end of the common dc motor speed motor, by speed motor feedback voltage to the dc power supply, to achieve the purpose of the dc motor speed control. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
