Abstract:

Switched Reluctance Machines (SRMs) are receiving significant attention from industries in the last decade. They are extremely inexpensive, reliable and weigh less than other machines of comparable power outputs. Although the design principles of the machine are available as a concatenation of many different sources, the need for a unified, step-by-step design procedure from first principles of electromagnetics is an absolute requirement. This dissertation discusses a procedure that can be applied by engineers with a basic background in electromagnetics. Subsequent to the design of the machine

Abstract:

Brushless dc motor drives have become increasingly popular, following recent developments in rare-earth permanent-magnet materials and the semiconductor devices used to control the stator input power and to sense the rotor position. They are now frequently used in applications such as flight control systems and robot actuators, and for drives which require high reliability, long life, little maintenance and a high torque-to-weight ratio. In many motor drives the presence of torque and speed ripples, especially at low speed, is extremely undesirable. The mathematical model developed in this the

This thesis describes a development of a high power density, high-speed 3-phase permanent magnet brushless dc motor developed specifically for use in aircraft and defence applications. The drive is essentially intended for low power, high-speed application and it incorporates an integral electronic controller. Special attention is paid to the geometry of the rotor assembly. The development of high power density permanent magnet machines has had several unsuccessful attempts by distinguished researchers. These past attempts made use of the concept of flux focusing technique which provides the a

Robust fault analysis (FA) including the diagnosis of faults and predicting their level of severity is necessary to optimise maintenance and improve reliability of Aircraft. Early diagnosis of faults that might occur in the supervised process renders it possible to perform important preventative actions. The proposed diagnostic models were validated in two experimental tests. The first test concerned a single localised and generalised roller element bearing fault in a permanent magnet brushless DC (PMBLDC) motor.

The work presented in this thesis is aimed at improving single phase permanent magnet brushless DC motors; including their operation, design, efficiency and smoothness.

The first of these areas concentrates on the improvement of the open circuit torque for a single phase BLDC motor. The open circuit torque is not only due to the slot openings, but is also contributed by the uneven airgap which is conventionally used to solve s

ABSTRACT The project work involves the performance evaluation of the Permanent Magnet Brushless DC Motor in different modes of operation. The Controlled electric motors play a vital role as the heart of the industrial automation. Therefore, the performance of the automated industry largely depends on the high performance motion control system. The performance is defined in terms of accuracy, smooth operation and also the simplicity of controlling scheme. In this work, the PMBLDC motor is operated in open loop mode and closed loop mode and the performance in both modes have been analyzed

碩士<br>國立臺灣科技大學<br>電機工程系<br>95<br>This thesis is focused on the application of three-leg buck dc-dc power converter for the adjustable dc-link voltage. As to the drive of permanent-magnet synchronous motors, system control is conducted by voltage space vector pulse-width modulation (VSVPWM). Current and rotor-flux-orientation under synchronous frame are introduced to promote the dynamic performances of starting and load variation. Voltage and current closed-loop control with three-leg buck dc-dc power converter is achieved. Interleaved pulse-width modulation is used to control dc-link voltage.

碩士<br>國立臺灣大學<br>電機工程學研究所<br>105<br>The Brushless Direct Current Motor(BLDCM) has attracted more and more attention because of its advantages such as small size, high efficiency, easy maintenance, and good speed performance. Because the BLDCM uses permanent magnet excitation, the interaction between the rotor magnets and the stator teeth of the machines will produce cogging torque. It is a kind of torque that is caused because of its own structure. It will be generated even when there is no armature current. Cogging torque will cause parasitic ripples which further leads to mechanical vibration
