Abstract: An electric cycle with a frame that may include a tube and an opening. The tube may extend from a first end to a second end and may define a tube interior volume in fluid communication with the opening. An electric power unit may be mounted to the frame proximal the second end of the tube and may have a cooling air inlet and an exhaust port. A cooling path may be defined through the tube interior volume and at least a portion of the electric power unit. The cooling path may be in fluid communication with the opening so that air may flow into the opening, through the tube, into the cooling air inlet and out of the exhaust port of the electric power unit.

Abstract: An electric motor includes a rotor and a stator. The stator surrounds the rotor, has a top half, a bottom half, and wire windings, and is fixed with respect to the drive-unit housing. The stator is cooled by gravity feed via a fluid supplied by an external source and flowing onto and past the top half. The motor also includes a fluid dam fixed relative to the stator. The fluid dam is configured to guide the fluid around the stator and shield the rotor from the fluid flowing past the stator thereby limiting an amount of the fluid between the rotor and the stator such that spin losses in the electric motor are controlled. An electro-mechanical drive-unit employing the above described electric motor is also disclosed.

Abstract: A transmission-mounted electric machine includes an integrated rotational position sensor. The rotational position sensor includes a rotor element and a stator element. The stator element is attached to a stator element of the transmission at a plurality of mounting points and includes an alignment adjustment mechanism. The rotor element of the sensor is slip-fit against a shoulder of a rotor hub and held in place using a wave spring.
