ABSTRACT:
A direct current (DC) brushless motor for automotive and HVAC applications utilizes a single angular contact bearing assembly to rotatably couple an exterior rotor to an interior stator. The single angular contact bearing assembly can be a double horizontal row ball bearing, a four point contact bearing, and a crossed cylindrical roller bearing. The rotor is staked to the bearing assembly by a hub-shaft. A cooling fan is disposed on the top of the rotor to cool internal control circuitry within the motor. The stator includes a winding set connector which is slideably engaged within a cavity of a deep draw support member.
