Abstract

The present invention provides a winding device of a divided type stator core. The present invention can continuously carry out winding at each magnetic pole part of a stator core under the condition that iron core components are assembled into a whole, even if the divided type stator core increases claw parts in the iron core components divided by magnetic pole up to the hilt to make gaps between the claw parts diminished. On one hand, the winding device conveys a magnetic pole to the stator iron arranged on a driving shaft by the driving shaft step-by-step; on the other hand, a copper wire passes through the claw parts. The magnetic pole part is orderly continuously wound by a coil. The winding device is provided with a mechanism making the stator iron dilate partly, orderly and outwards. The iron core components are mutually movably combined and assembled into a whole along a circumferential direction in a preset range synchronous with the rotation of the driving shaft.
