Abstract
A motor assembly includes an electric motor with an output shaft. A motor frame houses the electric motor so that the output shaft protrudes from an end of the motor frame. A plate assembly is coupleable about the output shaft to the end of the motor frame. The plate assembly has a cavity that houses motor drive electronics. The plate assembly further defines a duct that extends between a central opening and one or more openings on an outer radial wall of the plate assembly. A fan is configured to flow air over one or more surfaces of the plate assembly and causes to flow through the duct to inhibits heat transfer between the electric motor and the motor drive electronics.
