High torque-density machines

There is considerable research activity into the development of hybrid and full-electric automotives to replace conventional internal combustion engine technologies. The motivation is driven by significant environmental concerns relating to air pollution and to the reduction of our overall carbon footprint.

One of the key components in hybrid and full-electric vehicles is the electric motor that drives the vehicle and ultimately removes the need for an internal combustion engine. As such there has been a lot of interest in different motor technologies and topologies optimised for this application.

The objective of this research is to examine the design of conventional induction motors for automotive drive applications. These machines have been rather overlooked because they have been designed for standard industrial applications for which cost is the key factor. They have some particular advantages for vehicle applications: reliability, robustness and good mechanical and temperature performance. The key objective is to take a radical look at the conventional design process for induction machines and to develop new designs that are fully-optimised in terms of torque and power densities for automotive drives.
