Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator structure for solving motor resonance. Background technique [0002] The motor is generally composed of a stator and a rotor. The stator is fixed in the casing of the motor. The rotor is supported by a rotating shaft and separated from the stator by an appropriate distance. When the coil on the stator conducts current, it can generate a magnetic field. The basic operation mode of the motor is to use the magnetic field and the magnetic force of the magnet on the rotor to repel each other to make the rotor rotate and output power. When the rotor is rotated under force, the coil on the stator can be excited to generate current and output power. For the operation of the generator, the stator structure is the main part of the motor. [0003] The existing stator structure has the following problems: 1. The electromagnetic vibration noise of the motor is related to the natural ...

AI Technical Summary

Problems solved by technology

[0003] The existing stator structure has the following problems: 1. The electromagnetic vibration noise of the motor is related to the natural frequency of the motor itself, and the stator structure is the main part of the motor. In order to reduce the vibration and noise of the motor, the two frequencies should be staggered to prevent resonance. Therefore, it is of great significance to study the natural frequency characteristics of the stator structure to reduce electromagnetic vibration and noise; 2. Most of the existing stator structures on the market are injection-molded integrated structures, which are inconvenient to disassemble and install, resulting in reduced service life of the stator
