Abstract
A cooling system is provided for an electric motor having control circuitry and including a motor housing surrounding the motor. The motor drives at least one radial fan at one end thereof for directing airflow through the motor housing across the motor. A fan housing encloses the cooling fan and defines a diverter chamber radially outboard of the fan that is sized to divert a portion of the airflow away from the electric motor. A control box contains the control circuitry and includes a base having a heat sink for contacting the control circuitry. The base defines a plenum in communication with the diverter chamber and a channel in communication with the plenum and the heat sink to direct the diverted airflow across the heat sink.
