Head of Tirius, Dr Tim Allen, explains: “We are helping the university’s research team develop electric drive train technology typically found in ‘A-Class’ cars like urban runabouts and small family hatchbacks. Specifically we are currently looking at permanent magnet traction motors in a number of sizes and configurations, with a view to optimizing electronic control for each motor type.”
The research involves running each motor on a test rig through its full output range and mapping its torque output at many points to build up a performance profile. The design of the controller can then be matched to the motor characteristics. This should be able to ensure that the motor runs in its optimum operating zone as much as possible, maximizes motor life and regenerative braking, minimizing wear, and is as energy efficient as possible.
The design of the test rig is fairly simple, thanks to the TorqSense torque sensor from Sensor Technology.
“We are pleased to endorse TorqSense and the guys at Sensor Technology,” says Tim. “We have been using their devices for many years and in many different roles. The bottom line is that they are easy to use, accurate and great value - partly because they can be re-used once their original project has been completed."
