Summary: Brushless (safe, reliable), low-cost, low-distortion, efficient speed control of AC induction motors is required for fan and pump drives in mining, industrial and agricultural applications, over a speed range 100% to 75% in sizes 1.5 kW to 1500 kW at the most common rated speed of 1500 rev/min. Present drives are either expensive or brushed. The project will extend the work of Varispeed and UTS on a low-cost, brushless, twin-stator induction motor with speed variation by mechanical phase control, to develop new optimised, brushless, electronic, speed control using a novel rotor construction. 1. A new, efficient, brushless AC motor drive will be researched, proven and prepared for commercialisation. 2. A mathematical description of the drive will be developed. 3. Design methods for optimum design of the motor and controller will be prepared. 4. Design software for the drives will be completed. 5. The designs will be validated using full power tests on motors of commercially significant size.
