SURFACE COOLING STRUCTURE FOR FRAME OF MOTOR

摘要

PURPOSE: A cover surface cooling structure of an electric motor frame is provided to form a cooling pin on the frame and arrange a trip wire on the cooling pin, thereby improve the cooling performance. CONSTITUTION: A rotator is supported by a shaft(11) and rotates. A stator is positioned and fixed to be facing with the rotator. A frame(10) protectively supports the rotator and the stator by surrounding it. A cooling pin(20) is protruded to the outside of an exterior circumference of the frame. A trip wire(30) perpendicularly intersects in a front and back surface of the cooling pin, in a flowing direction of the fluid.
