STATOR, ELECTRIC MOTOR, COMPRESSOR, AND REFRIGERATING/AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/138866
Kind Code:
A1
Abstract:
Provided is a stator (100) comprising a first iron core (10A) and a second iron core (10B). The first iron core (10A) comprises: a first yoke (12A) extending in a circumferential direction having an axis (C1) at the center thereof; and first teeth (11A) extending toward the axis from the first yoke (12A). The second iron core (10B) comprises a second yoke (12B) adjacent to the first yoke (12B) in the direction of the axis (C1) and second teeth (11B) adjacent to the first teeth (11A) in the direction of the axis (C1). The first iron core (10A) is configured from a layered body of electromagnetic steel plates and the second iron core (10B) is configured from a thin band of a layered body of an amorphous metal or a nanocrystalline metal, or from a compression-molded body of a powder of an amorphous metal or a nanocrystalline metal. When the width of the first yoke (12A) in a radial direction having the axis (C1) at the center thereof is denoted by Y1, the width of the second yoke (12B) in the radial direction is denoted by Y2, the width of the first teeth (11A) in the circumferential direction is denoted by T1, and the width of the second teeth (11B) in the circumferential direction is denoted by T2, at least one of Y1 < Y2 and T1 < T2 is satisfied.
