Halbach motor is a novel permanent magnet (PM) motor. One-sided and sinusoidal field is produced by the special distribution of permanent magnets. The field can increase air-gap flux and decrease the rotor yoke flux, which can improve power density, efficiency and reduce volume and pulsating torque of motor. It accords with automated guided vehicle system's need: high efficiency, high power density, low pulsating torque. Full-digital drive system of AGV based on ADSP2188 is designed according to Halbach motor's distinguishing feature, Experiment results prove that Halbach motor has much more advantages in the AGV system than with traditional permanent magnetic motor.
