The Department of Electrical Engineering is organizing one day seminar on "Electronically Operated Special Motors" on 24th May 2012 at 2:00pm in S-07. A lecture on said topic will be delivered by eminent academician Dr. Tahir Izhar, UET Lahore, in the field of Electrical Engineering. The abstract of the topic is given below:
Electronically Operated Special Motors
Due to the recent development in permanent magnet materials, efficient high power semiconductor devices, and high power micro-controllers, there has been an emerging growth of Electronically Operated Special motors in numerous applications. The use of electronically operated special motors is increasing due to safety, comfort, and better performance. Drive-by-wire and intelligent cruise control systems with Electric Power Assisted Steering (EPAS) could be realized in future. These motors offer improved response, long life, and high reliability, lower cost and higher efficiency which is required in many servo-drive applications.
These machines are highly suitable for servo-drive applications due to their characteristics. Elimination of brushes, commutator and slip rings makes the design compact and robust. Simple, light weight and lossless rotor construction lead to low inertia and high efficiency. Low rotor inertia leads to quick dynamic response.
The lecture will include permanent magnet Brushless DC, Switched Reluctance, and stepper motors. The physical design, operation and characteristics of these motors will be introduced. The applications, pros and cons will be discussed. The issues related to the problems, future trends and research areas will also be identified.
