Title:
STATOR, MOTOR, COMPRESSOR, AND REFRIGERATION AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/026431
Kind Code:
A1
Abstract:
A stator (3) comprises a stator core (31) and a plurality of segment coils (32) fixed by wave winding to the stator core (31). The stator core (31) comprises first teeth (341) and second teeth (342) adjacent to the first teeth (341). The first teeth (341) each comprise a first main body (341a) and a first distal end part (341b). The second teeth (342) each comprise a second main body (342a) and a second distal end part (342b). The stator (3) satisfies θ1 > θ2, where: θ1 is the angle between a straight line L1 and a straight line L3, and θ2 is the angle between a straight line L2 and the straight line L3; L1 is the straight line that passes through a center (C1) of an outer end section of the first main body (341a) and an axis (Ax); L2 is the straight line that passes through a center (C2) of an outer end section of the second main body (342a) and the axis (Ax); and L3 is the straight line that passes through a center (C3) between the first distal end part (341b) and the second distal end part (342b) and the axis (Ax).
