A guide member includes a first diametrically directed side guide section and a second diametrically directed side guide section formed by bending a single member at a bent portion. The first diametrically directed side guide section guides predetermined portions of electric conductors on a diametrically directed side of a slot. Further, the second diametrically directed side guide section guides predetermined portions of the electric conductors on a diametrically directed side of another slot adjacent to the slot. The bent portion is supported by a supporting body.

An assembling device () includes a first arranging section (), a second arranging section (), eighteen support arms () for supporting coil segments (), a feeding part (), and a controller (). When the controller () drives a motor () to rotate the feeding part () in a counterclockwise direction D, a pressing roller () rolls in the direction Dalong a first guide portion (), and presses a base part () of the eighteenth support arm () in the direction D. Thus, the first to eighteenth support arms () are rotated in the direction Dto insert the base parts () of the first to eighteenth support arms () sequentially in a second guide portion () of the second arranging section (), so that the first to eighteenth support arms () are rotated in a clockwise direction Dto assemble the coil segments () while overlapping with one another.

Assembling device and method

The present invention pertains to a stator manufacturing method and a device therefor. All of segments are twisted in order to obtain a stator, the linear sections of the segments being inserted into slots in a stator core. The segments on the inner peripheral side are subsequently twisted after the segments on the outer peripheral side are untwisted. In order to achieve this, e.g., a fourth spindle that is positioned on the outermost peripheral side and is one of the first through fourth spindles for twisting the segments is disconnected from a fourth motor and brought to a non-rotatable state. The following is then performed in sequence: the third spindle is disconnected from a third motor and twisted, and the second spindle is disconnected from the second motor and twisted.

Stator manufacturing method and device therefor

A stator manufacturing apparatus is equipped with spindles as twisting and bending jigs, an inner guide having a first supply flow path and a suction flow path formed in the interior thereof, and an outer guide having a second supply flow path formed in the interior thereof. Further, the spindles have receiving members in which insertion recesses are formed. Through holes are formed in the receiving members, and the receiving members are formed with lateral holes therein which allow the interiors of the insertion recesses to communicate with each other.
