Motorized pulley
The present technique, in accordance with one exemplary embodiment, relates to a motorized pulley. The exemplary motorized pulley includes a rim or housing inside of which are disposed an electric motor and a gear assembly, which is configured to transfer torque of the electric motor to the housing. Thus, during operation of the motor, the exemplary pulley rotates the housing in relation to a support structure to which the motorized pulley is mounted. To improve the dissipation of heat generated during operation of the motor, the motor is thermally coupled to the frame. Additionally, the rotor shaft of the exemplary motorized pulley extends into the external environment surrounding the pulley, thereby facilitating the operation of a machine element located externally with respect to the pulley via the electric motor disposed within the pulley.

An electric-powered vehicle includes electric-powered drivers for driving wheels, a controller for controlling the electric-powered drivers to generate an assisting driving force in accordance with a vehicle operating force by an operator, and a brake-operation unit for applying braking forces on the wheels. The vehicle also includes a brake-operation detector for detecting a brake operation performed by the brake-operation unit. When the brake-operation detector detects the brake operation, the controller controls the drivers to reduce the assisting driving force. This structure solves a problem caused by simultaneous generation of the braking forces and the assisting driving force.
