Abstract
"Permanent Magnet Synchronous Machines are a class of machines that are attracting more attention in recent years; particularly in automotive and aerospace applications where the machines employed need to have certain qualities that include high power to weight ratio, reliability, low maintenance cost and easy controllability. Due to design and application changes in the recent years, there have been drastic changes in the magnetic behavior of the machine that could be explained only by using a three-dimensional (3-D) analysis. Effects worth mentioning are the end coil impact and the effects caused by the flow of eddy currents in the laminations that become predominant at high frequencies of excitation. These frequencies reach to the order of a few kilohertz for super high-speed applications.
This thesis investigates the effects of end coils and effects due to eddy current upon parameters like electromagnetic torque, force densities, operational inductance, ohmic losses and induced voltage using 3-D Finite Element Analysis. A commercially available transient FEA solver has been used and a method to simulate skin effect at high frequencies is described. Finally, the impact of these effects on performance of the machine has been discussed"--Abstract p. iii
