With the all-digital AC servo-systems, hub motor controller is also increasingly used in digital control systems. In order to meet the development trend of digital control, motion control systems they use stepper motors or full digital hub motor controller as executive motor.
As an open-loop stepper hub motor control systems, and modern digital control technology are intrinsically linked. In the current domestic digital control system, the stepper motor is widely used. With the all-digital AC servo-systems, hub motor controller is also increasingly used in digital control systems. In order to meet the development trend of digital control, motion control systems they use stepper motors or full digital hub motor controller as executive motor. While both are similar in the control (pulse train and direction signal), but the performance and applications in use there is a big difference.
