Embodiment Construction
[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0036] This embodiment provides an in-wheel motor, which relates to the field of electric vehicle manufacturing, such as figure 1 and figure 2 shown. The hub motor includes a motor shaft 4, a stator 3 arranged on the motor shaft 4, a hub body 1, and a rotor 2. The motor shaft 4 rotates and is installed in the hub body 1, and the stator 3 is arranged in the hub body 1, along the circumference of the inner wall of the hub body 1. There are a plurality of first clamping protrusions 11 protruding toward the interva...

The invention belongs to the field of electric vehicle manufacturing, and discloses a wheel hub motor. The wheel hub motor comprises a motor shaft, a stator, a hub body and a rotor, the stator, the hub body and the rotor are arranged on the motor shaft, the motor shaft rotationally penetrates through the hub body, the stator is arranged in the hub body, and a plurality of first clamping protrusions are arranged on the inner wall of the hub body in the circumferential direction at intervals in a protruding mode. The rotor comprises a plurality of silicon steel blocks and a plurality of magnetic steels; The silicon steel blocks are clamped to the first clamping protrusions in a one-to-one correspondence mode, and the magnetic steel is arranged between every two adjacent silicon steel blocks. The multiple first clamping protrusions are arranged on the hub body, the multiple silicon steel blocks are clamped to the first clamping protrusions in a one-to-one correspondence mode, clamping of the rotor and the hub body is achieved, the multiple first clamping protrusions are arranged in the circumferential direction of the inner wall of the hub body at intervals, the clamping effect is improved, and the silicon steel blocks are prevented from falling off.
Description
technical field [0001] The invention relates to the field of electric vehicle manufacturing, in particular to a hub motor. Background technique [0002] The hub motor is a motor installed in the wheel. Its biggest feature is that the power, transmission and braking devices are integrated into the hub, so the mechanical part of the electric vehicle is greatly simplified. The hub motor includes a hub body, a rotor core fixedly mounted on the hub body, a stator core matched with the rotor core, and a motor shaft. The stator core is connected to the motor shaft through an iron core bracket. [0003] The rotor core includes silicon steel blocks and magnetic steel arranged in a circle, and the magnetic steel is sandwiched between two adjacent silicon steel blocks to form a complete rotor. Colloid bonding is used between the silicon steel block and the magnetic steel, and between the silicon steel block and the inner edge of the hub body. Colloid bonding requires relatively high ...
