Abstract
A method and an apparatus of winding a wire for a stator core in which, in order to wind a wire on a plurality of poles provided along an outer periphery of a stator core, a tension acting on the wire during the time when the wire between a pole on which the wire is wound and a wire support passes on each of side formers is made lower than a tension acting on the wire from the time when the wire between the pole on which the wire is to be wound and the wire support has passed on one of the side formers to the time when the wire starts to come into contact with the other thereof. Therefore, even a relatively thick wire can be wound while being prevented from getting bend marks, whereby a quality as a stator can be improved.
