Optimal design of a bearingless switched reluctance motor

摘要

This paper presents a method of optimizing number of turns of the main and radial force winding for a bearingless switched reluctance motor (BSRM) with 12/8 teeth configuration based on its mathematical model. The radial force and torque of BSRM are analyzed on condition of different combinations of the magnetomotive force of two kinds of windings. The winding configuration has a strongly influence on the performance of BSRM. Effects of two kind of winding arrangements on mutual inductances for BSRM are analyzed, and its optimal winding structures are proposed.
