摘要
介绍了三相异步电动机的调速原理,并设计一台单绕组双速三相异步电动机。介绍了该电机的绕组连接方法,利用Maxwell 2D模块建立其二维有限元模型,然后分析了该电机不同极数的磁场分布情况以及转矩特性,验证了该电机性能的合理性。
This paper introduces the speed control principle of three-phase induction motor and describes the design of a single-winding two-speed three-phase induction motor.And it gives the windings connection method of the motor.The two-dimensional finite-element model of the motor is established by using Maxwell 2 D module,and then the magnetic field distribution and torque characteristics of the motor with different polesare analyzed.It verifies the reasonability of the motor performance.
