The embodiments of the present invention disclose a rotating electrical machine. The rotating electrical machine comprises a stator and a rotor, the rotor comprises a rotating shaft and magnetic poles fixed to the rotating shaft, a chamfer being provided on the radial outer surface of at least one of the magnetic poles; the stator comprises a stator core, the stator core being located on one side of the magnetic poles far from the rotating shaft, the chamfer overlapping with the stator core in the axial direction of the rotor. For the rotating electrical machine provided by the embodiments of the present invention, the harmonic reluctance is changed by providing a chamfer on the radial outer surface of the magnetic poles of the rotor and allowing the chamfer to at least partially overlap with the stator core in the direction of the rotor shaft, which reduces the resultant air gap field of the motor and thus the electromagnetic force of the motor, achieving the objective of reducing electromagnetic noise and improving user experience.
