This paper presents a CAN (Controller Area Network) Bus network elevator system of permanent magnet synchronous motor controller design, build, CAN Bus Network for the elevator control system and sent a car elevator system transmission medium, making the system work closely together for the elevator floor control transmission mode. Permanent magnet synchronous motor design is the elevator control system, the control system and the motor driving system with power protection systems design, brake positioning system, gated switching system, with each chain control system and adequate protection and operation, be used without machine room elevator structure create higher value in use.
