Abstract

This paper presents a complex study of the performance developed by an outer rotor induction motor with multipole stator winding. The novelty of the proposed structure consists in the replacement of the regular lap winding with a ring type one, which allows a higher flexibility in changing the number of pole pairs. The purpose is mainly to obtain a superior torque capability by changing the synchronous speed. This study is based on FEM, Simulink analyses, and experimental tests. A startup strategy for the reduction of starting time, current, and electric power consumption is developed as well.
