Title:
STATOR, ELECTRIC MOTOR, COMPRESSOR, AIR CONDITIONER, AND METHOD FOR MANUFACTURING STATOR
Document Type and Number:
WIPO Patent Application WO/2020/188733
Kind Code:
A1
Abstract:
A stator (3) comprises: a stator core (31); a three-phase coil (32) attached to the stator core (31) in a distributed winding; a first lacing member (331) for holding a first-phase coil (321) and a second-phase coil (322); a second lacing member (332) for holding the second-phase coil (322) and a third-phase coil (323); and a third lacing member (333) for holding the third-phase coil (323) and the first-phase coil (321). At a coil end (32a) of the three-phase coil (32), the first-phase coil (321), second-phase coil (322), and third-phase coil (323) are arranged in that order in the circumferential direction of the stator core (31). At the coil end (32a), the third-phase coil (323) is positioned closer to the center of the stator core (31) than the first-phase coil (321). There are more second lacing members (332) wound around the three-phase coil (32) than there are of at least one of the first lacing member (331) and the third lacing member (333).
