  • Patent number: 10804777
    Abstract: 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.
