- Abstract
- This paper proposes a novel rotor strategy for the spoke-type IPM machine (STIPMM) with four surface-mounted
ferrite magnets to increase torque density and decrease torque ripple. An asymmetrical rotor structure concept is used during
the design process to increase the efficiency of the two torque compositions of the STIPMM, the reluctance torque and the
magnetic torque. In this design, the torque is improved by ensuring that the maximum value points of the magnetic torque and the
reluctance torque are closer to each other. In order to excavate the greatest potentiality of the initial model, the Kriging method
and genetic algorithm are used to obtain the optimized model. To verify the analysis result, the frozen permeability method
(FPM) is employed to provide feasible insights into the separation of the torque components based on a 2-D finite element
method (FEM). To highlight the superiority of the initial model, a conventional STIPMM with symmetrical rotor structure is
adopted for comparison under the same magnet amounts, machine size and operating conditions.
