A stator for a simultaneous concentrated winding motor includes a core having 3&#xd7;m teeth, and 3&#xd7;m windings. The windings include at least a Uwinding and a Uwinding that belong to a U phase, a Vwinding and a Vwinding that belong to a V phase, and a Wwinding and a Wwinding that belong to a W phase. First lead wires of the Uwinding, the Vwinding, and the Wwinding extend, respectively, from the teeth on which the Uwinding, the Vwinding, and the Wwinding are arranged.

Stator, motor using stator, and method for manufacturing stator

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.
