A system for the supplemental generation of energy from the operation of a vehicle operation, and specifically to the generation of energy in connection with a vehicle's drum brakes in combination with brushless electric motor-generators. The system includes a rotational conveyor that operatively connects the drum to a coupler member attached to a generator so that rotation of the drum rotates the coupler member to create energy. A frame member may position and retain the generator in place relative to the drum.

A wheel support bearing assembly includes a wheel support bearing and a power unit. The power unit is that of an outer rotor design in which a stator is located at an outer periphery of the wheel support bearing and a rotor is located radially outward of the stator. A radial extension of the entire power unit is sized to be radially inward of a peripheral section of a brake rotor. An entirety of the power unit, excluding a mount part thereof to a hub flange, is sized to be situated in an axial range between the hub flange and a mount surface, on an inboard side of the wheel support bearing. The rotor includes an outer shell magnetic body, which is made from soft magnetic material and forms an outer shell of the power unit, and permanent magnets that are provided to the outer shell magnetic body.

The present disclosure relates to mechanical braking mechanisms used in electric motor applications. The present braking mechanisms may be configured as non-back-drivable mechanical brakes and provide immediate braking of the motors. According to one embodiment, a mechanical brake assembly for an electric motor may include a female disk including a groove and an abutment and a male disk including a projection, the male disk being in mechanical communication with a rotor of the electric motor. When the electric motor is energized, the projection of the male disk is configured to rotate with the rotation of the rotor of the electric motor, but when the electric motor is de-energized, the projection of the male disk is configured to travel within the groove of the female disk and abut the abutment of the female disk, thereby reducing the rotation of the rotor of the electric motor.
