The matching driver HBS57 is a new type of closed-loop stepper motor driver developed by our company based on more than ten years'experience in stepper and Servo Research and development. It adopts the latest special motor control dual-core DSP chip and applies vector-type closed-loop Control Algorithm Thus completely overcome the problem of open-loop stepping motor lost step, but also can significantly improve the high-speed performance of the motor, reduce the degree of heating motor and reduce the motor's high, medium and low-speed vibration So as to improve the processing speed and accuracy of the machine and reduce the energy consumption of the machine. In addition, in the motor continuous overload, the driver will output alarm signal, with the same reliability as AC servo system. Of course, the motor installation size and the traditional two-phase 42-57 series stepper motor is fully compatible, the traditional stepping drive scheme is easy to upgrade, and the cost compared with the open-loop stepper motor increase is not much, only equivalent to the traditional AC servo system 30-50% .
