Abstract

A Permanent Magnet Synchronous Motor (PMSM) was modeled using three-dimensional (3-D) dynamic motional finite element electrodynamic software. Accurate 3-D modeling of a PMSM is beneficial in studying the electromagnetic frequency (EMF), revolutions per minute (RPM), thermodynamics, torque, and stress of the PMSM. There is a linear relationship between the electromotive force (induced voltage), or “back EMF,” and the RPM of the PMSM. By using this simulation, the relationship between back EMF and RPM was determined. An experiment was performed to determine the back EMF using a 22-pole PMSM motor as a generator and a separate driving motor on a common shaft. Theoretical back EMF results were in good agreement with experimental back EMF results.

Summary of research results to be presented

Theoretical 3-dimensional electromagnetic motor modeling using rotational analysis indicated that the motor's rated flux was 0.03 V/Hz. Two methods of experimental data and subsequent data interpretation demonstrated that the rated flux was approximately 0.03 V/Hz (Webers), consistent with theory.
