Simulation and Analysis of Electromagnetic Performance of Permanent Magnet Synchronous Motor Based on Electro-Hydrostatic Actuator

Electro-Hydrostatic Actuator (EHA) is the mainstream actuator studied abroad in the field of multi electric actuator. It combines the advantages of flexible electrical control and high hydraulic output density, representing the development direction of multi-electric actuator. As the core component of EHA, permanent magnet synchronous motor is very susceptible to external disturbance, which makes its dynamic performance more complicated. To solve this problem, this paper studies the permanent magnet synchronous motor, establishes the finite element simulation model, explores the dynamic characteristics, which lays a foundation for the optimization design of the permanent magnet synchronous motor in the future.
