Abstract

In many areas of engineering, the improvements in material properties have enabled designers to create sophisticated and previously unrealizable geometries feasible. A new low cost integrated electric machine is designed, analyzed and characterized in this dissertation. The material properties and their effect on motor performance are discussed and examined, the motor design equations are developed and analyzed. The performance test results are compared to analytical expressions previously derived and verified by simulation. Due to the nature by which the machine develops torque, the machine requires an inverter with position feedback which is discussed in detail, additional motor geometries are also presented. In addition, an overview of Maxwell's equations and their applicability to the electromagnetic, magnetostatic and magnetodynamic problem is presented. Finally, a new method of solving the eddy current problem using the control-volume method is explained and numerical results are presented.
