ABSTRACT:
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.
