Design of CAN board circuits based on SJA1000 for vehicle motor drives systems

This paper presents a motor drive circui that is to provide motion control for DC motor which is designed to connect the computer's series port with the CAN fieldbus. The principles of design and the program flow chat are also introduced. The interfacing to the motor drive system is described. The system shows the control and configuration of the motor drive using H-bridge system and the CAN bus for the electric vehicle.
