Abstract: In order to achieve the design goal of super premium efficient induction motor, the design scheme was put forward. For proposed design scheme, the stator double stacked winding was first designed into singledouble layer unequalturn low harmonic winding, and the copper rotor was used, then, taking IM efficiency, start torque multiples and start current multiples as the optimization objectives, the Taguchi algorithm was used to determine the optimize design variables, and then, the reasonable subspace division was integrated with the response surface method to implement subspace optimization of IM based on differential evolution algorithm. Moreover, the design and analysis calculation of 22 kW 4pole threephase IM is implemented to validate the effectiveness of proposed design scheme of super premium efficient IM.
