Mathematical model of stepped rotor type 12/14 bearingless switched reluctance motor based on maxwell stress method
The stator of the stepped rotor type bearingless switched reluctance motor has two kinds of wide and narrow stator teeth. The wide stator teeth provide suspension force, and the narrow stator teeth provide torque, so the decoupling control of torque and suspension force could be realized. The rotor...

| description | The stator of the stepped rotor type bearingless switched reluctance motor has two kinds of wide and narrow stator teeth. The wide stator teeth provide suspension force, and the narrow stator teeth provide torque, so the decoupling control of torque and suspension force could be realized. The rotor consists of 14 rotor teeth, and the surface of each rotor tooth has a stepped structure, so that the motor can self-start from any rotor position. Although the motor with this special structure has certain performance advantages, it also leads to the complex distribution of air gap magnetic field, which brings difficulties to the establishment of mathematical model. In this paper, the integral path suitable for the stepped rotor structure is proposed and the mathematical model of the stepped rotor type bearingless switched reluctance motor is established according to Maxwell stress method. Finally, the finite element method is used to verify the correctness of the established mathematical model. |
