Abstract
Efficient use of energy is an important issue in the electrical engineering. Core loss comprise of eddy-current losses and hysteresis losses and directly affect motors performance. A Finite Element Method analysis of hysteresis effects in ferromagnetic materials was developed along with experimental procedures. An optimized cogging-torque model for a Surface Mounted Permanent Magnet Machine was derived. Analysis of the effects of hysteresis losses on the cogging torque was performed. Results yielded significant influence.
