Cooling apparatus for motor means to protect commutator from dust and moisture in cooling air |
摘要 |
Cooling air is introduced through an opening in a wall portion of the motor housing radially opposing the commutator. A deflecting surface is provided for deflecting the cooling air entering the motor through the opening away from the commutator and toward the armature so as to prevent direct contact of dust and moisture in the cooling air with the commutator.
