1. Advantages: (1) high resolution than the three-phase motor, suitable for the purpose of the high precision requirements. Step (2) under the same from the Angle of HB! 。 Stepper motor in high speed running of the region's big torque. 2. Disadvantages: the number of motor stator main more than 10 extremely, drive circuit of power tube also has more than 10, the motor and drive the structure of the complex, high cost, more suitable than OA occasions for FA occasions. 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.
