Patent ID: 8549729

Claim:
A method for fabricating a stator core and a back yoke of an outer rotor type BLDC motor in a direct coupling type washing machine, comprising the steps of: providing a base metal of a circular electric sheet having a predetermined diameter; and punching the base metal to form a back yoke at a periphery of the base metal, and divisional cores on an inside of the back yoke of the base metal at the same time, wherein the step of punching includes the step of forming the back yoke and the stator core, wherein the back yoke and the stator core have a predetermined distance therebetween, where the predetermined distance in formation of the back yoke and the stator core is a sum of a thickness of a magnet to be attached to an inside surface of the back yoke and a gap required to be maintained between the rotor and the stator in fabrication of the rotor.
