Abstract

The latest developments in high energy product permanent magnet materials have led to renewed interest in the permanent magnet (P.M.) synchronous motor. This is primarily due to the high efficiencies and power factors which may be obtained from the P.M. motor. If this device is to find its way into widespread industrial use, it is important that sufficient analytical skills be developed and detailed design information be transmitted to the motor design engineer, such that the inherent advantages of a P.M. motor are recognized and utilized. -- This work, then, presents a detailed analysis of both the transient and steady state behavior of the P.M. motor. Included, as well, are the derivations of three of the important parameters of P.M. motors, namely direct axis reactance, quadrature axis reactance and open circuit voltage. The analysis is then used to predict transient and steady state performance with reasonable accuracy. Tested results of four prototype P.M. motors are presented in order to provide correlation with, and verification of, the analytical results. -- Finally, a number of important parameter variations are undertaken, and important conclusions to the design, manufacture and testing of P.M. motors are presented.
