Abstract

Halbach motor is a novel permanent magnetic (PM) motor. Sinusoidal field is produced by the special distribution of permanent magnets. The field can increase the air-gap flux while decrease the rotor yoke flux. The result can improve power density, efficiency and reduce volume of the motor. DTC control based on DSP2812 is brought forward which aims at Halbach motor special permanent magnet structure, experiment results prove it can control Halbach effectively.
