Problems solved by technology

Equipment without high-quality dynamic balance has defects such as easy wear of equipment parts, high noise, and short service life of equipment.
For ultra-high-speed asynchronous motors, since the rotor is in a state of high-speed rotation, if the dynamic balance of the rotor cannot be adjusted, it will have a more serious impact on the motor components

Abstract

The invention discloses a rotor dynamic balance debugging method for an ultra-high-speed asynchronous motor. Advanced design and analysis ways, test instruments and technological ways are adopted; a rotor dynamic balance basic characteristic and a balance tray to-be-jumped position are determined in the design stage; and then by taking test data before dynamic balance debugging as guidance, a dynamic balance debugging scheme of the system is implemented. The dynamic balance debugging method for the ultra-high-speed asynchronous motor has the main characteristics of a technological process of designing, design analyzing and optimizing, testing and verifying, dynamic balance debugging and new design guiding, and a dynamic balance debugging idea.

Description

technical field [0001] The invention relates to a rotor dynamic balance debugging method of an ultra-high-speed asynchronous motor used in the field of motor manufacturing. Background technique [0002] The dynamic balance debugging of the electric motor is a key technology. Equipment without high-quality dynamic balance has defects such as easy wear of equipment parts, high noise, and short service life of equipment. For ultra-high-speed asynchronous motors, since the rotor is in a state of high-speed rotation, if the dynamic balance of the rotor cannot be adjusted well, it will have a more serious impact on the motor components. Contents of the invention [0003] The purpose of the present invention is to provide a rotor dynamic balance debugging method for ultra-high-speed asynchronous motors, which can debug the rotor dynamic balance level of ultra-high-speed asynchronous motors, improve the efficiency and success rate of dynamic balance debugging, and is an important...
