Abstract
A split type stator core winding device which can continuously form windings on each of divided core elements assembled in a single stator core having a small gaps between large claws of adjacent core elements by stepwise feeding the stator core per magnet pole (core element) by rotation of the driving shaft and by passing a copper wire through a gap between claws of adjacent core elements and placing windings on each magnetic pole (core element), which is provided with means for expanding outward a part of the stator core assembled of core elements each being movable in a specified range in the circumferential direction in synchronism with rotation of the driving shaft holding the stator core.
