| titleOfInvention | Inner rotor structure of brushless motor |
| abstract | The utility model discloses an inner rotor structure of a brushless motor, which comprises a rotating shaft and a rotor sleeved on the rotating shaft; the rotor comprises a chip part and an outer magnet part, the outer magnet part is in a hollow cylindrical shape, the outer magnet part is sleeved outside the chip part, the chip part is sleeved outside the rotating shaft, and the chip part is arranged into a cylindrical body with a cross section being a regular polygon. Compared with an inner circular magnetic ring and an outer circular magnetic ring, the magnetic ring saves more materials on the premise of keeping the outer diameter and the inner diameter unchanged; the outer magnet part adopts a shape of a regular polygon in the outer circle and the inner circle formed by a plurality of magnet sheets, so that the material can be saved, and the production cost can be reduced. The chip part is arranged into a polygonal column with a regular polygon cross section, and when the chip part is assembled with the outer magnet part, the friction force between the chip part and the outer magnet part is increased, the cogging torque of the inner hole of the outer magnet part is low, when the inner rotor rotates, the vibration and noise of the inner rotor are low, and the rotation efficiency is high. |
