STATOR CORE OF AN OUTER ROTOR-TYPE MOTOR FOR MINIMIZING THE LOSS OF MATERIAL BY BLANKING A CORE PIECE STEEL SHEET IN A LINEAR TYPE

摘要

PURPOSE: A stator core of an outer rotor-type motor is provided to make a core value part arranged in two columns to be missed to each other in a shape of being engaged with a slot part and to be blanked at the same time, thereby improving the efficiency of blanking processing.;CONSTITUTION: A yoke part(21) has the strip shape of a straight line. A bonding recess(26a) and a bonding protrusion(26b) are formed to be coupled to each other in both-sided end portions of the yoke part. A bending cutout part(25) is formed in the yoke portion. A core value part(22) is spaced in the longitudinal direction of the yoke portion. The core value part comprises a slot part(23). A gap(g2) between the end portions of the core value part is formed to be minimized.;COPYRIGHT KIPO 2010
