Abstract
Motor needs high efficiency, high power density and low pulsating torque in hybrid electric vehicle, traditional motors have their limits; 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. Full-digital electric-driven system of hybrid electric vehicle based on DSP2407A is designed according to Halbach motor's distinguishing feature.Experiment results prove Halbach motor has much more advantages in the system than traditional permanent magnet motor.
