“…Unlike ordinary motors, high-speed motors have the benefits of high rotational speed, little volume, and high capacity density, which are widely used in the fields of flywheel energy storage, blowers, compressors, circulating refrigeration systems, ship power supply systems, and aerospace engines [1][2][3][4] . High-speed permanent magnet motors are increasingly applied for high-speed fields because of their outstanding benefits with high efficiency and high-capacity density level, as well as the advantages of stator and rotor diversified structure and good control features [5][6][7] .…”

In this paper, a 30 kW and 60, 000 r/min high-speed permanent magnet synchronous motor (HSPMSM) was studied. We use the knowledge of motor design to determine the structural dimensions and materials of each part of the machine to create the electromagnetic design of the motor. The FEM model of the motor was created by finite element software, and the no-load and load characteristics for the motor were modeled and analyzed, which verifies the reasonableness of the design of the motor. A genetic algorithm was applied to carry out multi-objective optimization of the motor to obtain the optimized design solution, and the performance of the high-speed motor before and after the optimized design was compared. The simulation results indicate that the rated torque of the motor has been increased through the optimization, while the torque pulsation and the groove torque of the motor have been decreased, which effectively enhances the magnetic characteristic of the designed machine.
