Computer-aided design and experiment research of new type permanent magnet synchronous motor

Modern motor needs high speed, high efficiency, high power density and low pulsating torque; Halbach motor is a novel permanent magnet (PM) motor: one-sided and sinusoidal field is produced by special distribution of permanent magnets. The field can increase air-gap flux while decrease rotor-yoke flux and air-gap harmonic, which can improve power density and efficiency, reduce volume and pulsating torque of motor. Halbach motor design software based on MATLAB and finite element analysis software based on ANYAS reduce period of motor design greatly; Finite element analysis and experiment results prove Halbach motor has much more advantages than traditional permanent magnet motor.
