Abstract
A permanent magnet D.C. electric motor 36 includes a motor housing 29 having first and second ends. The second end 42 is substantially closed and has an end of a shaft 35 extending there from. The second end includes vent holes 20 therein. The first end 27 is substantially open. An end cap 31 closes the first end of the housing. The end cap 31 has venting holes 34 therein for permitting air to pass there-through to cool the motor. A splash shield 32 is integral with the end cap 31 and covers the venting holes 34 in such a manner to limit foreign matter from entering the venting holes while permitting air to flow through the venting holes.
