Abstract

Modern motor needs high speed, high efficiency, high power density and low pulsating torque, traditional rare earth permanent magnet motor manifests its limitation. Halbach motor is a novel permanent magnet motor. Analysis of Halbach motor based on ANSYS proves its merits: sinusoidal field, higher air gap flux and lower rotor yoke flux, which can reduce pulsating torque and improve power density, efficiency of the motor, these merits can improve its dynamic characteristics greatly.
