感应型无轴承电机磁悬浮力解析模型及其反馈控制感应型无轴承电机磁悬浮力解析模型及其反馈控制 年珩，贺益康 （浙江大学电气工程学院，浙江 杭州 310027） ANALYTICAL MODELING AND FEEDBACK CONTROL OF THE MAGNETIC LEVITATION FORCE FOR AN INDUCTION-TYPE BEARINGLESS MOTOR NIAN Heng, HE Yi-kang (College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China) ABSTACT: Due to the load disturbance and detecting error of radial displacement, the centers of stator and rotor of a bearingless motor do not coincide with each other in practical operation, which will influence the control performance of stable suspension. Based on its operation principle, a relatively accurate analytical expression of the magnetic levitation force for an induction……
