Description

technical field [0001] The invention relates to a noise reduction motor. Background technique [0002] The high rotation frequency of the existing motor directly leads to unstable operation, severe trembling, and great noise. Therefore, the actual use process will cause a bad use environment. [0003] Chinese patent 201010616543.8 discloses a motor rotor vibration reduction and noise reduction mechanism, which is suitable for small power or miniature induction motors. It includes a rotor and a rotating shaft. On the bearing and one end of which passes through the bearing to form an output shaft, the motor rotor structure also includes a vibration damping device, and the vibration damping device is symmetrically arranged between the rotor and the bearing, including a retaining ring and An elastic element, the retaining ring is sleeved on the rotating shaft, the elastic element is sleeved on the rotating shaft and has one end in contact with the retaining ring and the other e...
