Analytical and FEM Modeling of Electormagnetic Radial Force for Switched Reluctance Motor

This paper bases on the magnetic method combining the tensor maxwell in considering magnetic saturation method, in considering magnetic saturation effect and actual switched reluctance motor stator and rotor under the premise of very wide, deduces and sets up a analytical models of radial force which can apply directly to switched reluctance motor stator and rotor with unequal extremely arc equal two circumstances analytical models of radial force. This model conforms to the actual switched reluctance motor structure and operation characteristics and structure optimization design for switched reluctance motor, electromagnetic vibration and noise prediction and control provides theory basis. With a prototype as an example, this paper calculated results and the analytical model of the finite element analysis of the results compared to verify the correctness of the analytical model built.
