Title:
固定子構造及び平角線モータ
Document Type and Number:
Japanese Patent JP7423710
Kind Code:
B2
Abstract:
A stator structure and a flat wire motor are provided. The stator structure comprises a stator core (11,31), stator windings (12,32) and an avoidance layer (13,33). The stator core (11) has an inner cylinder cavity (111), and a plurality of iron core slots (112) arranged at intervals in a circumferential direction on an end face of the stator core (11). The iron core slot (112) is communicated with the inner cylinder cavity (111) via a slot opening (113). The stator windings (12) have a plurality of layers of flat wire conductor (121) wound in the iron core slots (112). The avoidance layer (13) is located between the slot opening (113) and a first layer of flat wire conductor (121) in a radial direction of the stator core (11). During the operation of the flat wire motor with this stator structure, the skin effect caused by the high-frequency change of the magnetic field will act on the avoidance layer (13), thereby reducing the skin effect generated at the first layer of flat wire conductor (121), weakening the influence of the slot leakage flux on the first layer of flat wire conductor (121), reducing the eddy current loss of the first layer of flat wire conductor (121), and further reducing the eddy current loss of the whole motor, and thus achieving the technical effect of improving the motor efficiency.
