The article based on Ansoft 14 Maxwell 2 d software for motor respectively in the air gap is 2.3 mm and the air gap is 1.8 mm under the situation of the simulation analysis, augmenting the gap is appropriate, can reduce the air gap permeance, weaken the harmonic magnetic field in air gap, so as to make the motor noise decreasing. The conclusion is verified by typical examples, this paper has certain reference significance to improve motor noise.
