Embodiment 1

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

Embodiment 2

[0048] Such as Figure 5 with Image 6 In the permanent magnet harmonic motor shown, the difference between the motor of this embodiment and the first embodiment is that the rotor mechanism is an inner rotor mechanism, and the stator mechanism is an outer stator mechanism.

[0049] See Image 6 In this embodiment, the outer stator, the supporting 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

The invention discloses a permanent magnet harmonic motor, which comprises a rotor mechanism, a stator mechanism and a support mechanism, wherein a plurality of permanent magnets are arranged on the rotor mechanism; the stator mechanism is matched with the rotor mechanism; bearing components are arranged on the support mechanism; the rotor mechanism is connected with the support mechanism through the bearing components; and magnetic regulation teeth on which distributed windings are arranged are circumferentially formed at a part of the stator mechanism close to the rotor mechanism. By the design, a magnetic regulation ring structure is eliminated, so that the number of parts in the harmonic motor is decreased, the harmonic motor has a simple structure, and an assembly process is simple; and in addition, the independent magnetic regulation ring structure is eliminated, so that the weight of the whole motor is decreased, the size of the motor is reduced, reduction in the unsprung mass of an electric vehicle is facilitated, and the stability and riding comfort of the vehicle are improved.

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, especially electric vehicles with high-efficiency, high-power-density in-wheel motor drive systems are considered to be the most advanced 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 i...
