Abstract: A method for fitting a ring coil in a channel formed in the inner circumference surface of a hollow cylindrical member comprises a step of deforming the ring coil by applying a force to one or more portions thereof radially outwardly. The deformation of the ring coil causes a reduction of the circumscribed circle diameter facilitating its insertion into the member.

Subsequently, the deformed coil is sequentially pressed to the bottom surface of the channel are around so that the deformed coil is returned to its original shape and the whole of the coil is perfectly fitted in the channel.

Abstract: An apparatus reduces the insertion-required force in a coil inserting apparatus. A coil and an insulating material piece are automatically inserted into the groove of a stator core by the operation of a coil pusher.

When the insertion pressure has suddenly increased, the current stops to keep fundamentally the coil wrapping jig synchronous to the motion of the coil pusher.
