Abstract

The invention discloses a permanent magnet synchronous motor drive control system based on an IPM module. The permanent magnet synchronous motor drive control system based on the IPM module comprises a microprocessor module, an isolation drive module, a sensor module, the IPM module, an encoder and a battery pack, wherein the isolation drive module and the sensor module are connected with the microprocessor module; the IPM module is connected with the isolation drive module; the encoder is connected with the sensor module and is arranged in cooperation with a permanent magnet synchronous motor; the battery pack is connected with the IPM module; the battery pack, the IPM module and the permanent magnet synchronous motor are connected in sequence; the sensor module is further connected with the IPM module and the isolation drive module. The permanent magnet synchronous motor drive control system based on the IPM module can overcome the defects that the energy utilization rate is low, the stability is poor and the reliability is low in the prior art, and has the advantages of being high in energy utilization rate, good in stability and high in reliability.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to an IPM module-based permanent magnet synchronous motor drive control system. Background technique [0002] Compared with hybrid electric vehicles and fuel cell vehicles, pure electric vehicles have the advantages of no pollution, low noise; The future development direction of new energy vehicles. The motor drive system is a key component of electric vehicles. Its output characteristics determine the dynamic characteristics of electric vehicles. At the same time, its efficiency will directly affect the efficiency of electric vehicles. [0003] At present, the driving motors of electric vehicles at home and abroad mostly use induction motors and permanent magnet synchronous motors. Compared with induction motors, permanent magnet synchronous motors have the advantages of high power density and torque density, high efficiency, high power factor, high reliability and easy mai...
