Title:
ROTATING ELECTRIC MACHINE STATOR MANUFACTURING METHOD AND ROTATING ELECTRIC MACHINE STATOR MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/080097
Kind Code:
A1
Abstract:
Disclosed is a rotating electric machine stator manufacturing method including: a step for bringing the leading end portions of one coil piece and another coil piece for forming a stator coil of a rotating electric machine into contact with each other; and an irradiation step for irradiating a laser beam having a wavelength of 0.6 μm or less toward one side on the exposed side of the contact surface of the leading end portions. The irradiation step involves scanning the laser beam in a loop shape while moving the laser beam in the travel direction, which includes a directional component along which the one side extends. The amount of movement in the travel direction per scanning loop is less than or equal to the diameter of the laser beam.
