摘要

本文介绍了一种无轴承绕线转子感应电动机。采用旋转电机模型的瞬态有限元法计算了无轴承异步电动机径向力和转矩的瞬态响应。结果表明，可以同时产生稳定的径向力来支撑轴重和独立于轴承电流的恒定转矩。将无轴承绕线转子异步电动机与无轴承鼠笼式异步电动机在径向力和转矩的瞬态响应方面进行了比较。提出了一种实现悬浮与旋转结合的控制系统。

Transient FEM computation of radial force and torque for bearingless wound-rotor induction motors

This paper presents a bearingless wound-rotor induction motor. The transient responses of radial force and torque in bearingless induction motors are computed with the transient finite element method (FEM) with rotating machine models. It is shown that a steady radial force to support the shaft weight and a constant torque independent of the bearing currents can be generated at the same time. The bearingless wound-rotor induction motor is compared to the bearingless squirrel cage induction motor with respect to the transient responses of radial force and torque. A control system is proposed to implement the combination of levitation and rotation.
