| Zusammenfassung: | The invention discloses a brushless motor. The brushless motor comprises a stator assembly, a rotor assembly and a fan blade, wherein the rotor assembly is arranged in the stator assembly, the fan blade is fixed on a shaft core of the rotor assembly, a straight-line knurling part is formed on the shaft core, and a through hole of the fan blade is in interference fit with the straight-line knurlingpart so that the fan blade is fixed on the shaft core. Compared with the prior art, the straight-line knurling part is formed on the shaft core of the brushless motor, and the through hole of the fanblade is in interference fit with the straight-line knurling part so that the fan blade is fixed on the shaft core; by interference fit of the fan blade and the straight-line knurling part, radial rotation of the fan blade can be prevented, axial displacement of the fan blade can be effectively prevented, so that the fan blade is prevented from falling off from the shaft core, and the working stability of the motor is imp |
