ABSTRACT:
A recording disk drive motor is disclosed which is employed in a recording disk drive that retains a removable recording disk that has a diameter of 30 mm or less, as well as a method of manufacturing a stator core used in the same. The core back of the stator core in the motor has an arc shaped inner circumferential surface therein that is offset from the center thereof. The stator core is produced from a laminated body having a stator core, a chuck frame that is integral with and surrounds the stator core, and connector arms that connect the stator core and the chuck frame and integral therewith. After the windings are wound around the stator teeth, the stator core is cut from each connecting arm and the stator core is removed from the chuck frame.
