The second inserted portion generates a stronger elastic force of recovery than the first inserted portion when the groove inserted portion is inserted into the insertion groove.

In a motor, a magnet is configured so that four pairs of S-poles and N-poles are formed at equal angular intervals, and a stator core has six salient poles formed thereon. Of the plurality of salient poles, when the first salient pole or the second salient pole faces a position between an S-pole and an N-pole, the other salient pole faces the center of an S-pole or the center of an N-pole. The radial-direction lengths of the first salient pole and the second salient pole among the plurality of salient poles are longer than the other salient poles, and the radial-direction length of the portion of the first coil wound around the first salient pole and the radial-direction length of the portion of the second coil wound around the second salient pole are longer than the radial-direction lengths of the other salient poles.

An apparatus is provided for winding a laminated core with a magnet coil for an electric motor in which a conductive, insulated coil wire is wound into one or multiple pole tip grooves of a winding surface of the laminated core. The apparatus comprises a holding device, a counter holding device, and one or multiple clamping elements. The holding device is configured to fix the laminated core to be wound during a winding process. The one or multiple clamping elements are configured to fix an insulating paper to one of the one or multiple pole tip grooves.

An arrangement for mounting a coil winding on a stator tooth, the arrangement comprising a mounting element having a first mounting arm for receiving a first stator tooth and a second mounting arm for receiving a second stator tooth, wherein the first mounting arm is movable relative to the second mounting arm between a first position and a second position; means for mounting an electrical conductor on the first stator tooth and the second stator tooth when the first mounting arm is in the first position relative to the second mounting arm to form a coil winding on the first stator tooth and the second stator tooth; and means for placing the first mounting arm in the second position relative to the second mounting arm when the conductor has been mounted on the first stator tooth and the second stator tooth to allow the first stator tooth and the second stator tooth to be removed from the first mounting arm and the second mounting arm respectively.

A stator for a motor of a compressor includes a stator core, insulator, coil, slot insulator, and inter-coil insulator. The stator core has a plurality of tooth portions arrayed circumferentially. The insulator is fitted to axial end faces of the stator core. The coil is wound on the tooth portions. The slot insulator is placed within slot portions that are spaces between circumferentially neighboring ones of the tooth portions, and which are interposed between the stator core and the coil. The inter-coil insulator is placed between circumferentially mutually neighboring windings of the coil. The inter-coil insulator is sheet shaped and folded over a width equal to double a sheet thickness at a folding-bottom portion extending along an axial direction. The folding-bottom portion is positioned on a distal end side of the tooth portions. Movement of the folding-bottom portion in a radial direction toward the rotor is restricted.
