Abstract
It is an object of the invention to provide a technique for easily installing many turns of a coil winding on a stator. Representative method for manufacturing a motor includes preparing the coil wound into a ring-like form and tied, preparing the split core such that the spacing between the pair pole pieces in the circumferential direction of the split core corresponds to the inner dimension of the coil in the circumferential direction of the split core, inserting the tied coil into the two coil receiving parts through the openings and then, deforming the split core such that the spacing between the pair pole pieces is increased to be longer than the inner dimension of the coil.
