An electric motor having a reverse air flow cooling system that eliminates the need to extend lead wires past the fan. The electric motor includes a fan positioned on the lead-end of the motor to move air through a housing of the electric motor in a direction generally defined from the shaft-end of the motor to the lead-end of the motor. Lead wires can extend from the stator windings radially through the housing for connection to an electric start switch. The electric start switch can be positioned in a control box that is coupled to the housing. The electric start switch can be operable to remove an auxiliary circuit from a stator circuit after startup of the electric motor.

Electric motor having a reverse air flow cooling system

An apparatus comprising a driven element, a driving element operably coupled to the driven element, and a shield coupled to the driving element such that the shield at least partially covers at least one of the driven element and the driving element. The driven element includes a housing with an outer surface. The outer surface has a first raised portion and a first non-raised portion, the first non-raised portion at least partially surrounding the first raised portion, the first raised and first non-raised portions define a first surface pattern. The shield has an outer surface with a second raised portion and a second non-raised portion. The second non-raised portion at least partially surrounds the second raised portion, defining a second surface pattern substantially similar to the first surface pattern.
