摘要:
A stator in which stator coils (10) are formed by a plurality of unit coils (4) arranged so as to be shifted from each other in the circumferential direction and each having: a first slot-accommodated portion (41a); a second slot-accommodated portion (41b); a first terminal wire (42a) extending from the first slot-accommodated portion (41a); a second terminal wire (42b) extending from the second slot-accommodated portion (41b) and shifted from the first terminal wire (42a) by one line of a conductive wire; a terminal-side coil end portion (42c); and first and second anti-terminal-side coil end portions (43a) and (43b), wherein the first terminal wire (42a) and the second terminal wire (42b) of the respective different unit coils (4) are joined with each other.
摘要:
A method for manufacturing a stator, the method comprising a step of winding one conductive wire to produce unit coils (404), a step of forming a coil basket (406) having an inner diameter of a terminal or an anti-terminal side greater than an inner diameter of the anti-terminal side, resp. the terminal side, wherein each unit coil and the other unit coil overlap each other, a step of inserting, from the terminal side or the anti-terminal side of the coil basket (406), an inner core (302a) formed by a plurality of teeth (321) radially arranged at regular intervals along the circumferential direction and connection portions (321a) connecting radially-inner-side ends of the adjacent teeth, a coil basket contraction step of applying a force from an outer circumferential side to the coil basket (406) in which the inner core (302a) is inserted and a step of pressing, into an outer core (302b), the inner core (302a) to which the contracted coil basket (406) is mounted.
