The vast improvements made in the development of rare earth magnets, power electronics and micro-electronics over the last two decades can claim to be the major driving forces behind the rapid growth of permanent magnet (PM) brushless motor drives. The state of the art in PM motor technology is the PM universal motor, i.e. a combination of a PM synchronous and a PM brushless direct current (DC) motor. The PM universal motor has the capability to operate as a variable speed DC shunt motor with high torque at low speeds, and also as a synchronous motor at constant speed with high efficiency. The literature on synchronous and PM brushless motors is very extensive, although no studies have dealt with the concept of a PM brushless universal motor in any detail. The objective of this thesis is to develop an energy efficient, high performance, reliable and inexpensive electrical motor to replace induction motors, in the 21st century. Initial research of different AC motors highlighted the importance of correctly designing electrical motors. The different PM synchronous motors used in this study revealed that a sound knowledge of the motor's performance characteristics, at the design stage, is crucial to the successful and optimal design of any PM motor. 2014-11-10T08:54:55Z 2014-11-10T08:54:55Z 1996 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/9473 eng application/pdf Department of Electrical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
