【Abstract】 In this paper, we use the finite element method to calculate the static magnetic field of permanent magnet oscillation motor, and apply the method of Maxwell force to calculate detent torque of the motor. We work out the magnetic field and detent torque of stator teeth for different sizes, analyse the effects on detent torque when change the size of stator teeth, and compare the calculation values with the method of magnetic circuit. The results match well with the experiments.更多还原
