Experimental Verification of High Winding Factor Model of a Motor with Two Controllable Rotors

Abstract

A number of machines have been fitted with electric motors and their inverters. To reduce the space of the motors and inverters, motors with two controllable rotors using a six-phase inverter have been proposed. However, the winding factor of three-phase and six-phase rotors in a conventional winding arrangement are 0.87 and 0.50, respectively. In order to improve the winding factor of the motor, we propose a novel winding arrangement and verify its effectiveness using finite element analysis.
