Abstract

A new method for CAN-based multi-motor synchronous system is presented. A PMSM driver with CAN interface was designed, and the software with the function of synchronous control is also completed. The communication protocol is designed, and effective anti-interference measures are adopted to ensure good electromagnetic compatibility. The clock synchronization of different devices in the system is implemented by sending synchronization packets. The experimental results show that the system has good performance, and is worthy of being used abroad.
