ABSTRACT:
A baffle and lead guide is provided for an electric motor with a reverse air flow cooling system for the motor. The motor includes a shell housing a stator assembly and a rotor assembly, the rotor assembly including an axially extending shaft. A first end shield closes one end of the shell and a second end shield closes the second end. The shaft is rotatably journaled in at least one of the first and second end shields and extends through at least one of the first and second end shields. A fan is fixed to the shaft between the rotor and the second end shield to rotate with said shaft. Leads extend to the second end shield through the motor shell from the stator assembly. The baffle is positioned axially adjacent the fan. Preferably, the baffle is annular in shape and includes at least one axially extending leg which defines a lead chute radially outboard of the fan to guide the lead wires past the fan.
