Embodiment 1

[0036] Such as figure 1 The shown permanent magnet harmonic motor comprises: a rotor mechanism 1, which is provided with several permanent magnets 2; the shape of the permanent magnets 2 can be many kinds, wherein, it is preferably rectangular; the permanent magnets 2 and There are many connection relationships of the rotor mechanism, among which, it is preferably embedded in the rotor mechanism. When the rotor rotates at a high speed, the permanent magnets are not easy to fall; in addition, the distribution of the permanent magnets 2 can have There are many kinds, among which, it is preferred to be V-shaped distribution, and every two adjacent V-shaped permanent magnets 2 have opposite magnetic poles; the harmonic motor also includes a stator mechanism 3, which cooperates with the rotor mechanism 1, wherein the stator mechanism There is an air gap between 3 and the rotor mechanism 1; a support mechanism 8 is provided, and a bearing assembly 10 is provided on the support mecha...

Embodiment 2

[0048] Such as Figure 5 and Figure 6 The difference between the permanent magnet harmonic motor shown in this embodiment and the motor in Embodiment 1 is that the rotor mechanism is an inner rotor mechanism, and the stator mechanism is an outer stator mechanism.

[0049] see Figure 6 , in this embodiment, the outer stator, the support mechanism 8 and the end cover 9 are respectively fixed on the outer ring of the bearing assembly 10 . The rotor is fixed on the shaft 11, and the supporting mechanism may be a cylinder.

Abstract

A permanent magnet harmonic motor comprises: a rotor mechanism (1) with several permanent magnets (2) disposed thereon, a stator mechanism (3) fitted with the rotor mechanism (1), and a support mechanism (8) with a bearing assembly (10) disposed thereon. The rotor mechanism (1) is connected to the support mechanism (8) through the bearing assembly (10); magnetic regulating teeth (4) are circumferentially formed at a part of the stator mechanism (3) close to the rotor mechanism (1), and distributed windings (6) are arranged on the magnetic regulating teeth (4). The number of parts in the permanent magnet harmonic motor is reduced; the permanent magnet harmonic motor has a simpler structure, and an assembly process is simple. In addition, the weight of the whole motor is reduced, and the size of the motor is reduced, which facilitate the reduction in the unsprung mass of an electric vehicle, thereby improving the stability and riding comfort of the vehicle.

Description

technical field [0001] The invention relates to a permanent magnet harmonic motor. Background technique [0002] In order to solve the world's energy shortage and environmental pollution problems, electric vehicles have become a research hotspot for automobile manufacturers and research institutions due to their significant advantages of high efficiency and low emissions. State-of-the-art drive methods. [0003] The motor is the core component of the wheel drive vehicle, and the high-performance motor determines the rapid development of electric vehicles. At present, there are mainly two types of electric motors for hub-driven electric vehicles: outer rotor motors and inner rotor motors. In order to meet the actual speed requirements of the wheels, the inner rotor motor needs to be matched with a complex planetary gear reduction mechanism, which greatly increases the volume and weight of the entire transmission system, and the investment cost increases accordingly. In add...
