SINGLE MAGNETIC CONDUCTIVE PLATE STRUCTURE FOR FORMING SINGLE POLE PLATE BRUSHLESS DC MOTOR, PUNCHED TO FORM POLE PLATE, POLE PLANES, AND AXIAL HOLE

摘要

PURPOSE: A single magnetic conductive plate structure is provided to simplify the structure, and reduce manufacturing costs and overall thickness of the plate. CONSTITUTION: A single magnetic conductive plate comprises a pole plate(11) made of a single magnetic conductive sheet(10), wherein the pole plate serves as a base plate to be coupled with a coil; a plurality of pole planes(12) protruded in a vertical direction from the pole plate; and an axial hole(13) formed at the center of the pole plate. The pole plate, pole planes, and the axial hole are integrally formed in the single magnetic conductive plate. The pole planes are spaced apart from each other at constant intervals along the circumference of the axial hole.
