Embodiment Construction

[0025] Figure 1~4 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~4 The present invention will be further described.

[0026] Such as Figure 1~2 As shown, a hub motor with low harmonic content for an electric vehicle includes a stator and a hub 9 fitted on the outer ring of the stator. The hub 9 is made of non-magnetic material.

[0027] The inner ring of the hub 9 is provided with 8X (X is an integer) slots, and a magnetic block 1 made of a magnetic material is mounted in each slot. The cross-section of the magnetic block 1 is flat shovel-shaped. The outer ring of the magnetic block 1 is provided with a block that matches the shape of the card slot. The inner ring is an arc-shaped surface. , the stator is placed within the circumference.

[0028] The stator includes a stator fixed block 5 with a circular cross section. The stator fixed block 5 is made of non-magnetic material. A stator shaft 6 is installed at the axis of...

Abstract

The invention discloses a wheel hub motor with low harmonic content for electric vehicles, which belongs to the technical field of automobile electric appliances. It includes a stator and a rotor, and is characterized in that: the rotor includes a hub (9) and a magnetic block (1) on its inner surface; the stator is located inside the hub (9), and the stator includes a stator fixing block (5) and several parts of its outer ring The stator core (4), each stator core (4) includes two stator poles, the auxiliary winding (3) and the armature winding (8) are wound on the stator pole of the stator core (4); the stator core (4) A permanent magnet (2) is arranged in the middle obliquely; the armature winding (8) is arranged with multi-phase, and the multi-phase armature winding (8) is sequentially wound on the stator poles of different stator cores (4). In the wheel hub motor with low harmonic content of the electric vehicle, by setting the auxiliary winding in the stator core, the defect of non-adjustable excitation of the permanent magnet brushless wheel hub motor in the prior art is solved, and the economy is improved.

Description

technical field [0001] The invention discloses a wheel hub motor with low harmonic content for electric vehicles, which belongs to the technical field of automobile electric appliances. Background technique [0002] The hub motor integrates the motor and the transmission device into the hub, which greatly simplifies the transmission mechanism of the electric vehicle, and at the same time can make the design of the electric vehicle flexible and diverse. At the same time, the in-wheel motor has the characteristics of independent drive of a single wheel, so it can be realized relatively easily whether it is front-wheel drive, rear-wheel drive or four-wheel drive. Full-time four-wheel drive is very easy to implement on a vehicle driven by a wheel hub motor. [0003] At present, electric vehicles mainly use permanent magnet brushless hub motors, which have significant advantages such as simple structure, reliable operation, small size, less loss, and flexible shapes and sizes of ...
