Abstract

The effects of compression on the magnetic properties of a steel alloy used in electromagnetic devices is investigated. The results of a case study on a switched reluctance motor are presented. It is demonstrated that compression affected the winding inductance profiles as well as the performance characteristics of the motor. The simulated performance results are verified by comparison to experimental data. The switched reluctance motor winding inductances were determined from a series of nonlinear magnetic field solutions in conjunction with an energy perturbation approach. A comparison of the inductance values with measured data, as well as the performance characteristics of the machine, revealed that, in cases of high stress conditions due to casing force fitting, the compression effects on the magnetic characteristics of the stator laminations should be taken into account
