Abstract

The invention discloses a motor fault diagnosis method and apparatus, and an electric appliance. The motor fault diagnosis method comprises: acquiring vibration signals operated by a motor; according to the preset matching algorithm, performing matching processing for the vibration signals operated by the motor to obtain the matching result; and according to the matching result, determining whether faults exist in the motor. The motor fault diagnosis method can improve the motor fault diagnosis efficiency.

Description

technical field [0001] The invention relates to the detection field, in particular to a motor fault diagnosis method and device and an electrical appliance. Background technique [0002] With the improvement of living standards, various household appliances are constantly integrated into people's lives, which brings great convenience to life. For example, range hoods, as one of the necessary facilities in electrical kitchens, are convenient for people to get rid of oily fumes when cooking, and are more and more valued by people. The huge market demand has brought unlimited business opportunities for the development of the range hood industry. At the same time, it also puts forward higher requirements for the stable operation and noise index of the range hood. For example, while the range hood meets the noise index, Has a large air volume. However, under the premise that the air volume of the range hood is consistent, when the motor of the range hood fails, the noise of the...
