A Software for analysis of permanent magnet AC motors

Bulgan, Deniz
Nowadays permanent magnet motors became very popular in almost every area of industry such as automotive, aerospace and automation due to having higher efficiency, better torque-speed characteristics, longer life, higher dynamic response, higher torque per volume when compared to brushed DC and induction motors. These advantages made PM motors very essential and the need of design and analysis of PM motors became more important with the need of specialized applications. In this thesis, a previously developed MATLAB based analysis approach will be improved to obtain an analysis tool for analysis of permanent magnet AC motors. The software will be tested with experimental data. As a result of this study, a software for analyzing surface mount permanent magnet motors is developed. By using the developed software user can obtain the solution of electrical and magnetic circuit solutions of the motor, see performance characteristics from graphics and see the lamination drawing from the machine dimensions and electrical limitations. The results of the software is compared with the experiment results of a manufactured motor and differences between results are explained.


A Novel Noise Reduction Technology for Switched Reluctance Motors
Bizkevelci, Erdal; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2008-07-24)
The conditions are sought at which an SIR motor can be operated with highest efficiency, while producing a desired torque output at low shaft torque ripple. The investigation is based on the simulation software that uses measured flux-linkage (V, 0, 1) and static torque (T, 0, 1) characteristics of a given motor. The variation of the shaft torque, torque ripple and efficiency of the motor Is investigated, while the control variables "advance angle" and "conduction angle" are swept over their range with a co...
Calculation of core losses of a six-phase induction motor with third harmonic current injection
Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
A control algorithm to minimize torque ripple and acoustic noise of switched reluctance motors
Bizkevelci, Erdal; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2008)
Despite its simple construction, robustness and low manufacturing cost, the application areas of SR motors are remained limited due to the high level of acoustic noise and torque ripple. In this thesis work, two different type of controllers are designed and implemented in order to minimize the acoustic noise and torque ripple which are considered as the major problems of SR motors. In this scope, first the possible acoustic noise sources are investigated. A sliding mode controller is designed and implement...

Permanent magnet synchronous motors (PMSM) and asynchronous induction motors (IM) are widely used in the industry for a diverse set of applications. Although the use of induction motors is increasing for industrial applications due to cost inconsistency in rare earth magnets, PMSM motors are still being used because of their compact size, high power density, and greater efficiency. In interior permanent magnet synchronous motor (IPMSM) and surface mounted permanent magnet synchronous motor (SPMSM), the non-...
