Description
Summary:Propulsion architectures within current electric vehicles do not exploit the versatility and potential of electric motors as they are implemented on axle and require mechanical drivetrain components. These transfers generate torque from the motor to wheels and result in large number of complex components, space utilization and energy losses due to several moving parts. A direct driven in-wheel motor, placed inside the rim of a vehicle, exceeds such designs. Recent development in electromagnetic research enabled usage of direct driven electric motors for passenger vehicle operation, ensuring adoption in the largest segment of automotive industry. Production technologies differ vastly when comparing these with traditional high-speed electric motors and the following paper introduces production methods to meet low manufacturing costs.
