BRUSHLESS DC MOTOR WITH A SLOTLESS STATOR IN WHICH A COIL WINDING PROTRUSION IS FORMED ALONG THE CIRCUMFERENCE OF THE OUTER CIRCUMFERENCE OF A BOBBIN BODY PART AT A CONSTANT INTERVAL

摘要

PURPOSE: A brushless DC motor with a slotless stator is provided to supply the large output of a direct current motor by winding a large amount of coils around a bobbin to the longitudinal direction of a rotary shaft.;CONSTITUTION: A body part(220) forms a through hole(210) and inserts a rotor. A plurality of coil winding protrusions(230) is formed to be projected along the outer circumference of the body part at a constant interval. A coil is wound. A fixing protrusion is projected in both sides of the coil winding protrusion and fixes a groove(410) which is formed in a second insulator(400a) and a first insulator(400).;COPYRIGHT KIPO 2012
