Abstract
An electric motor having a rain baffle which is supported relative to and within the motor housing to prevent rain or the like which may enter ventilation outlets in the housing from contacting the rotor shaft bearing and the electrical components positioned within the housing. The rain baffle is also supported relative to and within the motor housing to allow air used to cool the motor to pass around the perimeter of the baffle and out the ventilation outlets in such a way as to substantially minimize the exhaust air from being recirculated back into air inlet vents in the housing.
