Study on the Rotor Levitation of one High Speed Switched Reluctance Motor

One two-phase switched reluctance motor with a magnetic levitated rotor is presented for high speed applications. Firstly the lamination configuration and the rotor pole shape are optimized through electromagnetic field calculations. Then the production of radial forces is investigated and the characteristics are calculated. Based on the analysis, the motor structure for the levitation of the laminated rotor is proposed. And the radial forces with similar amplitude can be generated at any rotor angular positions, and are decoupled inherently in this structure
