DESIGN OF A NOVEL CONCEPT OF SYNCHRONOUS MOTOR FOR TORQUE RIPPLE IMPROVEMENT

Abstract : In this paper, a novel design of synchronous machine is presented, the Multi-Stack Flux Modulating Machine (MSFModM). The MSFModM is made of 2 separate machines combined together into one multi-stack structure. The 2 combined stators share the same concentrated armature winding. A 2-D electromagnetic Finite Element Model (FEM) is built for a 3-phase 6/4 motor (6 stator teeth, 4 rotor teeth) and a Magnetic Equivalent Circuit (MEC) is used to evaluate the 3-D effect of the multi-stack machine and to correct the 2-D FEM flux linkage evaluation. The MSFModM concept is compared to a Biased Flux Permanent Magnet Motor (BFPMM). The two motors are supplied by three-phase sine wave currents and comparisons are carried out in terms of flux linkage, back-EMF and torque as the MSFModM exhibits a lower torque ripple.
