Abstract
A cooling assembly includes an electric motor 10 for driving a fan 16. At least one spoke structure 18 is coupled to and extends generally radially from a periphery of the motor body so as to be exposed to airflow caused by rotation of the fan 16. An electronic component 24 of the motor is operatively associated with the spoke structure 18 such that heat of the electronic component is conducted to the spoke structure and to a spoke extension 22.
Claims20
A motor assembly comprising:
- an electric motor for driving a fan, the motor having a main body,
- at least one spoke structure coupled to and extending generally radially from a periphery of the main body so as to be exposed to airflow caused by rotation of the fan;
- and
- an electronic component of the motor operatively associated with the spoke structure such that heat of the electronic component is conducted to the spoke structure.
