Title:
STATOR CORE, STATOR UNIT, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/075275
Kind Code:
A1
Abstract:
The present invention obtains a stator core in which iron loss can be more reduced than a conventional one and dimension accuracy control is facilitated. The stator core (16) is formed by laminating a plurality of core plates (24) and housed in the case (14) of a motor (10). The plurality of core plates (24) include an elastic projection-attached core plate (24A) in which a plurality of elastic projections (28) are provided side by side in the circumferential direction, said elastic projections (28) extending from the outer circumference portion toward the radial-direction outside and bending in the axial direction. The stator core (16) is then supported by the case (14) in a state in which the plurality of elastic projections (28) make contact with the inner circumferential surface of the case (14) and bend elastically.
