The invention discloses a motor system efficiency improving system and device, and a permanent magnet synchronous motor for a vehicle. The motor system efficiency improving system comprises a CAN communication receiving and transmitting module, a torque coordination module, a frequency conversion control module and a motor control module. Instruction information sent by a vehicle control unit is received through the CAN communication receiving and transmitting module, the instruction information is analyzed, then the analyzed instruction information is processed through the torque coordination module, target instruction information is acquired, the target instruction information is processed through a frequency conversion control module to acquire frequency information and current loop control parameter information, a motor control mode is switched through a motor control module according to the target instruction information, and the motor efficiency is improved according to the frequency information and the current loop control parameter information. Closed-loop control of the motor is realized through the motor control module according to the current loop control parameter information, and the motor efficiency is improved according to the frequency information.

    本发明公开一种电机系统效率提升系统、装置及车用永磁同步电机。电机系统效率提升系统包括CAN通信收发模块、转矩协调模块、变频控制模块以及电机控制模块,本发明先通过CAN通信收发模块接收整车控制器发送的指令信息,对所述指令信息进行解析,然后通过转矩协调模块对解析后的指令信息进行处理,获得目标指令信息,再通过变频控制模块对目标指令信息进行处理,获得频率信息和电流环控制参数信息,再通过电机控制模块根据目标指令信息对电机控制模式进行切换,并根据频率信息和电流环控制参数信息提升电机效率。本发明通过电机控制模块根据电流环控制参数信息实现电机的闭环控制,并且根据频率信息提高电机效率。
