Abstract:
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, including 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, whereby forming the stator core and the back yoke at the same time reduces working hours and saves material.
