Embodiment Construction

[0018] A noise control method for a permanent magnet motor, comprising the steps of:

[0019] Step 1: Install noise sensors at multiple positions of the permanent magnet motor;

[0020] Step 2: The noise sensor transmits the monitored noise signal to the central control unit;

[0021] Step 3: The central control unit analyzes the temperature signal to determine where the noise occurs;

[0022] Step 4: The central control unit issues an instruction to activate the noise reduction device at the position where the noise is generated.

[0023] Further, there are multiple noise reduction devices, which are evenly arranged at various positions of the permanent magnet motor, and each noise reduction device is connected to the central control unit.

[0024] Further, the noise reduction device is a partition structure made of attracting material.

[0025] Further, a comparison unit is provided in the central control unit, and the comparison unit compares the noise signal with a nois...

Abstract

The invention discloses a noise control method for a permanent magnet motor. The noise control method comprises the following steps that 1, noise sensors are mounted in multiple positions of the permanent magnet motor; 2, the noise sensors transmit monitored noise signals to a central control unit in real time; 3, the central control unit analyzes temperature signals, and determines positions where the noises are generated; and 4, the central control unit sends out an instruction to start corresponding noise reduction apparatuses which are located in the positions where the noises are generated. By adoption of the noise control method for the permanent magnet motor provided by the invention, the noises of the permanent magnet motor can be monitored in real time; the noise reduction apparatuses in different positions can be switched on or switched off according to different noises, so that noise control on the permanent magnet motor is performed effectively.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a noise control method for permanent magnet motors. Background technique [0002] After the motor is assembled, the motor often has noise problems caused by different reasons, such as electromagnetic noise, ventilation noise [0003] Noise, due to the noise caused by the resonance of the casing, the noise caused by the quality of the bearing, the vibration noise caused by the unbalanced rotor, etc., when the existing motor detects the noise, there are external factors such as the vibration noise of the motor body, which cause the motor noise detection error , so that the analysis is wrong, the use effect is not good, the anti-repair rate of the motor is increased, and the production effect is reduced. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a scientific and reasonable noise control metho...
