Paper Title:
Cogging Torque Reducing in Dual-Rotor Motor by Suitable Selection Inner and Outer Slot Opening Widths
  Abstract

In order to reduce the cogging torque in dual-rotor permanent magnet (PM) ring torque motor, the expression of cogging torque is deduced on the motor, and the influence rules of the resulting cogging torque are analyzed with change the inner and outer slot opening widths. According to the dual-rotor PM ring torque machine, the method for reducing the cogging torque amplitude and leading a reverse phase torque curve by suitable selection of the inner and outer slot opening widths is proposed. The results of simulation show that selecting the appropriate slot opening widths can effectively reduce cogging torque by the finite element simulation method.
