Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0025] Preferred embodiment:

[0026] The preferred embodiment discloses a permanent magnet synchronous hub motor. like figure 2 As shown, the permanent magnet synchronous hub motor includes a stator core 7, a magnetically conductive material 4 sleeved outside the stator core 7, a rotor outer ring 1 sleeved outside the magnetically conductive material 4, and a rotor outer ring 1 sleeved outside the rotor outer ring 1. The hub 8. A plurality of embedding grooves are arranged on the magnetic permeable material 4 , and a permanent magnet 5 is embedded in each embedding groove, and the magnetic poles between adjacent permanent magnets 5 are opposite (that is, the arrangement of NSNS is adopted). The embedding groove is a structure recessed inward from the surface of the magnetically permeable materi...

Abstract

The invention discloses a permanent magnetic synchronous wheel hub motor and an electric vehicle, and belongs to the field of electric vehicles and parts thereof, aiming at addressing the problem of unstable installation of permanent magnets in current structure. According to the invention, the permanent magnetic synchronous wheel hub motor includes a stator core, a magnetic conductive material which sleeves the outside of the stator core, a rotor outer ring which sleeves the outside of the magnetic conductive material and a wheel hub which sleeves the outside of the rotor outer ring. The magnetic conductive material is provided with a plurality of embedded grooves thereon, each embedded groove is embedded with one permanent body, and the adjacent permanent magnetic bodies have opposite magnetic poles. According to the invention, the electric vehicle includes the permanent synchronous wheel hub motor. According to the invention, the permanent magnetic synchronous wheel hub motor and the electric vehicle herein are more secure and reliable compared with current surface-mounted structures, and does not cause the permanent magnet to have displacement even the torque output is increased. Further, the wheel hub motor has the characteristics of stable working status in terms of the entire motor, long service life, higher cost performance and lower manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicles and their accessories, in particular to a permanent magnet synchronous hub motor and an electric vehicle including the permanent magnet synchronous hub motor. Background technique [0002] Electric two-wheeled vehicles (mainly including electric bicycles and electric motorcycles) mostly use hub motors. The existing wheel hub motor mainly adopts the outer rotor structure, such as figure 1 As shown, the outer side of the stator core 7 is sequentially provided with a magnetic material and the rotor outer ring 1, and the permanent magnet 5 (magnetic steel) is surface-mounted on the surface of the magnetic material, forming a gap between the stator core 7 and the magnetic material. air gap6. [0003] The structure in which the permanent magnet 5 is pasted on the surface of the magnetically permeable material with anaerobic adhesive is poor in firmness. When the torque output reaches a certa...
