Title:
STATOR, ELECTRIC MOTOR, COMPRESSOR, REFRIGERATION CYCLE DEVICE, AND METHOD FOR PRODUCING STATOR
Document Type and Number:
WIPO Patent Application WO/2024/009350
Kind Code:
A1
Abstract:
The present invention comprises: a cylindrical stator core (34); a first coated wire including a first conductor wire which, between a first conductor wire and a second conductor wire having different hardnesses, is harder than the second conductor wire, and an insulating coating covering the circumference of the first conductor wire; and a second coated wire including the second conductor wire and an insulating coating that covers the circumference of the second conductor wire and has a thicker thickness than that of the insulating coating covering the circumference of the first conductor wire. The first coated wire and the second coated wire are wound in an intermingled manner around a plurality of teeth sections (36) provided along the circumferential direction of the stator core (34). As a result, it is possible to suppress the occurrence of short circuits and burnout in a coil (35).
