Abstract

The invention provides a motor and an air conditioner, and relates to the technical field of the air conditioner. The motor is used for driving a fan of the air conditioner; a rotor of the motor is arranged in a stator; the gap between the outer wall of the rotor and the inner wall of the stator is 0.23-0.27mm; two end rings are arranged on the two end planes of the rotor respectively; and the endrings adopt trapezoidal sections, and the trapezoidal bottom edges are connected to the end planes of the rotor. By adoption of the structural dimension, the harmonic noise resistance of the motor isimproved, motor harmonic noise can be eliminated, drone generated when the motor is applied to the air conditioner is avoided, and noise quality is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a motor and an air conditioner. Background technique [0002] At present, the air conditioners sold on the market always make a humming sound during use, and the customer experience is poor. For this reason, air conditioner sellers or manufacturers often receive complaints from customers. For this reason, the air-conditioner manufacturer has failed to effectively solve the problem of reducing the noise of the air-conditioner. [0003] Therefore, how to reduce the noise of the air conditioner is a technical problem to be solved urgently at present. Contents of the invention [0004] The object of the present invention is to provide a motor and an air conditioner, which aims at at least partially solving the technical problem of the existing air conditioner with relatively high noise during use. [0005] The first technical scheme provided by the present invent...
