Since the bearingless flux switching permanent magnet motor has a doubly salient pole structure of conventional flux switching permanent magnet motor, there are many problems, such as high cogging torque, high torque ripple, and the magnetic flux leakage produced by PMs, which affect the characteristics of the electromagnetic torque and suspension force. To overcome the shortcomings above, a novel method-right angle chamfering scheme, is investigated to reduce the cogging torque. Firstly, based on the given rated speed and rated power, the parameter ranges of the angle variables at both ends of the permanent magnets are designed by the empirical formulas. Then, under the condition that the torque and the power are reduced in allowable ranges, the electromagnetic characteristics, such as cogging torque, harmonic, electromagnetic torque, radial suspension force, and decoupling, are simulated and analyzed in detail. Based on the proposed design method, the compromise design of the above design objectives is considered and realized. Finally, the scheme of stator and rotor component is built, and the experimental results show that the effectiveness and feasibility of the scheme are verified. |
