Embodiment Construction

[0029] The invention discloses a stator iron core of an axial magnetic field motor, which can reduce the notch harmonic wave of the stator slot of the stator iron core, and the stator slot can be applied to copper wire windings of different structures.

[0030] Such as figure 1 Shown is the stator core 1 of the axial field motor in the prior art, the stator slot 12 of the stator core 1 is provided with a notch (that is, the opening between two adjacent stator teeth 11), and the stator The harmonics at the notch position of the iron core 1 are very chaotic, and if not dealt with, the eddy current loss of the copper wire winding in the stator slot 12 will be relatively large. At present, in order to reduce the harmonic wave of the notch of the stator slot 12 , a method of reducing the width of the slot of the stator slot 12 on the stator core 1 is generally adopted. After reducing the slot width of the stator slot 12, the inside of the stator slot 12 is only suitable for round ...

Abstract

The invention discloses an axial magnetic field motor stator iron core. The axial magnetic field motor stator iron core comprises a lower iron core and an upper iron core which are stacked up and down, wherein the lower iron core is used for being provided with a copper wire winding, and the upper iron core is used for enabling a stator groove of the lower iron core to form a closed groove. According to the axial magnetic field motor stator iron core provided by the invention, the notch harmonic of the stator groove of the stator iron core is reduced, so that the stator groove can be suitablefor copper wire windings with different structures, and a motor with better performance can be provided.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an axial magnetic field motor stator core. Background technique [0002] The stator core 1 includes a stator yoke and a plurality of stator teeth 11, such as figure 1 As shown, between the stator teeth 11 is a stator slot 12 for placing copper wires. [0003] The magnetic field when the motor is running is divided into fundamental waves and harmonics. The harmonics at the notch position of the stator slot 12 are very chaotic. If not dealt with, the eddy current loss of the copper wire winding in the stator slot 12 will be relatively large. At present, in order to reduce the harmonic wave of the notch of the stator slot 12, the method of reducing the notch width of the stator slot 12 on the stator core 1 is generally adopted, that is, the notch width of the stator slot 12 is smaller than the width inside the slot, such as attached figure 1 shown in . The stator core 1 of this s...
