One of the major causes of global warming and climate change is the production of green house gas associated with thermal power generation. Over 60% of generated electric power is consumed by electric motors. For many years, the applicant has been developing high efficiency interior permanent magnet (IPM) motor technology. High efficiency reduces consumption of electric energy which helps in the fight to counteract global warming by reducing gas emission. Over the previous 5-year grant period, the applicant focused on solving the basic design issues of standard line start IPM motors. This has resulted in significant contributions. The published research results have aroused considerable industrial interests and international collaborations. The applicant has received five major IEEE Awards, which indicates that his work is considered very significant by his peers and by industry. However, the demand of fast and precision control of speed is spearheading the design and development of advanced new electric motor drive systems. Thus, the objectives of the proposed research for the coming 5-year period are: a) Development of interior permanent magnet (IPM) traction motor drives for electric and hybrid electric vehicles having highly efficient performances, (b) Design and build energy efficient motor drives using intelligent controllers, c) Design and test innovative new technology for power inverters utilizing new wavelet modulation techniques. These objectives will be achieved in both software and hardware developments. Three Laboratory prototypes will be built and tested. These will be realized with the help of 8 undergraduate, 4 Masters and 9 PhD students and 5 post doctoral fellows. The scientific approaches will involve detailed analysis, design and development of system models and associated power electronics and control interfaces. High performance and efficient motion control technology will dominate the specific applications market worldwide including Canada. The topics of the proposed research on advanced electric machines and power electronics system are significant for economic exploitation in Canada. A five-year grant of $67,000 per year is requested to achieve the objectives of the proposed research.
