Claim 8:
9. An electric motor assembly, the electric motor assembly comprising:
an electric motor having a rotor shaft that extends along a rotor shaft axis of the electric motor, the electric motor being operable to rotate the rotor shaft;
a motor frame that houses the electric motor, the rotor shaft protruding from the motor frame;
a cooling fan; and
a motor drive electronics assembly removably mounted to a non-drive end of the motor frame between the motor frame and the cooling fan, the motor drive electronics assembly having a cavity that houses motor drive electronics, the motor drive electronics assembly further defining a duct that extends, from a inlet formed on an end surface of the motor drive electronics assembly that is distal to the motor frame, to one or more outlets formed on an outer radial wall of the motor drive electronics assembly,
wherein, during operation of the cooling fan, air blows on the end surface of the motor drive electronics assembly, and air blows through the duct by entering the inlet and exiting the one or more outlets, and
wherein the duct is in fluid communication with the cooling fan via an axial channel defined in the motor drive electronics assembly about the rotor shaft.
