Problems solved by technology

For the current motor, when the motor has high-frequency electromagnetic resonance and the electromagnetic noise is too high, it is necessary to disassemble the motor, redesign the electromagnetic scheme of the motor to change the electromagnetic frequency of the electromagnetic rotational force wave, and replace the motor with a different number of slots. The rotor is used to reduce the noise of the motor, and the processing process is complicated

Abstract

The invention provides a motor and a method for controlling the motor to perform noise reduction. The motor comprises a pedestal, a stator iron core and at least two connecting pieces; wherein each connecting piece is connected with the pedestal and the stator iron core respectively, and the stator iron core is fixed in the pedestal. The rigidity of each connecting piece is adjustable, and adjustment is realized through external force acting on any one of the connecting pieces. According to the scheme, the rigidity of the connecting pieces of a motor is adjusted through external force, noise reduction processing can be carried out on the motor, and the implementation mode is simpler.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a motor and a method for controlling the motor to reduce noise. Background technique [0002] Electromagnetic noise is one of the main noise sources of electric motors. The direct cause of electromagnetic noise is that when the motor is running, there are electromagnetic rotating force waves of a specific frequency. When the electromagnetic frequency of these force waves is the same as the mechanical frequency of the high-frequency vibrating stator core, high-frequency electromagnetic resonance is generated, resulting in electromagnetic The noise is too high. [0003] At present, the stator core of the motor and its base are usually welded. For the current motor, when the motor has high-frequency electromagnetic resonance and the electromagnetic noise is too high, it is necessary to disassemble the motor, redesign the electromagnetic scheme of the motor to change...
