Abstract

The invention discloses a low-harmonic winding, the pole number p of an axial flux motor is equal to 5 * k, the slot number z of the axial flux motor is equal to 9 * k, the low-harmonic winding is a centralized winding and comprises a main winding and an auxiliary winding, and each of the main winding and the auxiliary winding comprises three phase windings. Each phase winding of the main winding comprises 2k coils, each phase winding of the auxiliary winding comprises k coils, and k is an even number. The low-order harmonics generated by the main winding and the auxiliary winding are the same in order, the same in frequency and close in amplitude, and the initial phase angle difference is close to 180 degrees. Therefore, the low-order harmonics generated by the main winding and the auxiliary winding can be counteracted mutually, so that the use performance of the axial flux motor is improved. In addition, by adopting the low-harmonic winding in the invention, a fundamental wave with a relatively large amplitude can be obtained, and the fundamental wave is a useful wave. The invention further discloses an axial flux motor and a winding method of the low-harmonic winding.

Description

technical field [0001] The present invention relates to the technical field of axial flux motors, and more specifically relates to an axial flux motor, a low harmonic winding, and a winding method for the low harmonic winding. Background technique [0002] The concentrated winding of the axial flux motor is: the two effective sides of the coil are placed in two adjacent stator slots. Concentrated windings are easy to mass-produce, but the harmonics of the armature magnetic field of concentrated windings are abundant. Harmonics, especially low-order harmonics, will increase the eddy current loss and iron core loss of the motor, and deteriorate the vibration and noise. [0003] However, problems such as eddy current loss, iron core loss, vibration and noise of the centralized winding have not been given sufficient attention in the prior art. On the one hand, it is due to the fact that the motor has low requirements on eddy current loss, core loss, vibration and noise in most...
