Patent ID: 8661651

Claim:
A method for manufacturing a stator for a rotary electric machine, comprising: an annular stator core that is formed by laminating and integrating magnetic steel plates; and concentrated winding coils that are mounted to respective teeth of said stator core, said method for manufacturing a rotary electric stator comprising: a bobbin installing step in which bobbins each including a trunk portion and a pair of guide portions that are disposed so as to protrude from two longitudinal ends of an upper surface of said trunk portion are installed such that longitudinal directions of said trunk portions are oriented in a radial direction of said teeth, and so as to place bottom surfaces of said trunk portions alongside two axial end surfaces of said teeth; and a concentrated winding coil mounting step in which a conductor wire is wound a predetermined number of times around said teeth so as to pass through a concave space that is formed by said trunk portions and said pairs of guide portions at two axial ends of said teeth; a tension supporting arm insertion portion is formed in advance so as to pass longitudinally through said trunk portion of said bobbin; and a tension supporting arm is inserted through said tension supporting arm insertion portion prior to said concentrated winding coil mounting step such that a winding tightening force of said conductor wire is borne by said tension supporting arm in said concentrated winding coil mounting step.
