Description
Summary:The use of in-wheel motors, often referred to as hub motors, as a source of propulsion for pure electric or hybrid electric vehicles has recently received a lot of attention. Since the motor is housed in the limited space within the wheel rim, it must have high torque density and efficiency and survive the rigors of being in-wheel in terms of environmental cycling, ingress, shock and vibration, and driver abuse. Finally, to ensure that adequate levels of functional safety are met, it is essential that failures do not lead to the loss of control of the vehicle. This paper presents studies of a fault-tolerant concept for the design of in-wheel motors. The study focused on achieving a high torque density and the ability to sustain an adequate level of performance following a failure. A series of failures is simulated and then compared with experimental tests on a demonstrator motor.
