Claim 10:
11. A motor drive electronics assembly configured for use with an electric motor, the motor drive electronics assembly comprising:
a first end configured to be removably mounted to a non-drive end of a motor frame of an electric motor;
a second end opposite the first end and having a cooling duct inlet;
an outer radial wall with one or more cooling duct outlets;
a cooling fan positioned to blow air on the second end;
motor drive electronics within a cavity, the cavity defined at least in part by the outer radial wall; and
a cooling duct extending from the cooling duct inlet to the one or more cooling duct outlets, wherein, during operation of the cooling fan, air blows on the second end of the motor drive electronics assembly, and air blows through the cooling duct by entering the cooling duct inlet and exiting the one or more cooling duct outlets, and
wherein the cooling duct is in fluid communication with the cooling fan via an axial channel defined in the motor drive electronics assembly about a rotor shaft of the electric motor.
