Abstract
The present invention relates to an in-wheel motor comprising: a motor assembly including a rim, a cover, a shaft, a stator, and a rotor, a magnetic type encoder including a ring-shaped magnet rotating together with the cover, and an encoder sensor for sensing a magnetic flux of the ring-shaped magnet; and a shielding unit coupled to the cover.
Claims21
1-20. (canceled)
An in-wheel motor comprising:
- a rim that has a cylindrical shape, the rim having a first opening and a second opening that face each other;
- a cover that is coupled to the rim and covers the first opening and the second opening to thereby define a sealed space inside the rim;
- a shaft that is disposed at a center of the rim and extends in an axial direction of the rim;
- a motor assembly disposed inside the rim and configured to provide rotational force to the rim, the motor assembly comprising (i) a stator that surrounds the shaft and is coupled to the shaft and (ii) a rotor that surrounds the stator and is configured to rotate about the shaft;
- a shielding portion detachably coupled to the cover;
- a ring-shaped magnet disposed in the shielding portion and configured to rotate together with the cover, the ring-shaped magnet being replaceable;
- and
- a magnetic encoder located axially between the shaft and the cover, the magnetic encoder being connected and fixed to the shaft in the axial direction,
- wherein the magnetic encoder comprises an encoder sensor configured to sense a change of magnetic flux of the ring-shaped magnet.
