High Speed Switched Reluctance Machines

As consumers and governments push for more energy efficient vehicles, design of light weight, low cost, high efficiency powertrains has become a necessity to meet increasing performance requirements.  The objective of this research initiative is to investigate the suitability of high speed switched reluctance machines as a solution to current challenges in the automotive industry.

Switched reluctance machines are magnet-less motors renowned for their robust structure, fault tolerance, and large torque density. These advantages make reluctance machines a low cost piece of equipment capable of enduring the harshest and most rigorous environments.  These advantages also make switched reluctance machines a prime candidate for high speed applications.  High speed operation generally reduces weight, and in some cases, can even reduce costs compared to other motors of similar power capacities operating at lower speeds. For these reasons, SRM’s are expected to become more prevalent in the automotive and aerospace sectors in the future.

Applications of ongoing research include primary traction drives for bus or utility vehicles, starter motor-generators for gas turbines, flywheel energy storage systems, and large machine tool drives.

This research was undertaken, in part, thanks to funding from the Canada Excellence Research Chairs Program.
