Abstract: The present disclosure discloses a rotor of an induction motor comprising a rotor body (1), alternating rotor teeth (2) and rotor slots (3) arranged along a circumference of the rotor body (1), and a plurality of grooves (4) provided at an end of the rotor teeth (2) or a plurality of voids (5) provided within the end of the rotor teeth (2) that are provided symmetrically about a center line (10) of the rotor teeth (2). The rotor and the induction motor having the rotor of the present disclosure can, for example, reduce the radial force of the stator caused by the slotting effect by about 50%. Therefore, the user's comfort can be greatly improved, while the efficiency of the induction motor can be improved, and the life of the induction motor can be prolonged.

Abstract: The present disclosure discloses an electric-machine housing, which effectively solves the technical problem in the prior art that electric machines have high NVH level. The electric-machine housing is circumferentially provided with a plurality of axial tunnels, and the tunnels are empty or are filled with a damping medium. The structure in which the tunnels are empty or the tunnels are filled with the damping medium can weaken the excitation to the electric-machine housing by the stator vibration, increase the damping coefficient of the electric-machine housing, weaken the transfer paths of vibration and noise, and reduce the amplitude of electromagnetic force waves, thereby inhibiting vibration and noise, to effectively reduce the overall NVH level.

Abstract: The present disclosure discloses an electric-machine stator lamination, an electric-machine stator iron core and an electric machine, which effectively solves the technical problem in the prior art that electric machines have high NVHs. The yoke of the electric-machine stator lamination is circumferentially provided with a plurality of axial tunnels, and the tunnels are empty or are filled with a damping medium. The electric-machine stator iron core is formed by laminating a plurality of the electric-machine stator laminations or is integrally manufactured. The electric machine includes an electric-machine housing and the electric-machine stator iron core, the outer circumference of the electric-machine stator iron core and an inner wall of the electric-machine housing have gaps therebetween, and the gaps are empty or are filled with a damping medium. The structures in which the gaps/tunnels are empty or the gaps/tunnels are filled with a damping medium can weaken the vibration energy generated by the stator to the electric-machine housing, increasing the damping coefficient of the electric-machine housing, reduces the response amplitude/frequency of the electric-machine housing, weaken the paths of the vibration/noise transmission, and reduce the response amplitudes, thereby inhibiting vibration and noise, to effectively reduce the overall NVH level.
