摘要
本文在介绍汽车转向泵用无刷直流电动机结构的基础上,用有限元法分析计算了该永磁无刷电动机的磁场分布和静态特性,并利用静态计算所得参数分析计算了电动机起动和负载突变时的动态特性,得到的磁密分布波形和静态转矩特性为该种电动机设计使用提供了理论依据。
The brushless DC motor used in turning pump of automobile is introduced in this paper. Magnet field distribution and static characteristic of permanent-magnet brushless DC motor are calculated by finite element methods. Dynamic characteristic is simulated during starting and transient load changing. The flux density distrubtion and the static torque characterstics offers the theoretic for the design of the motor.
