Description

Technical Field

[0001] This utility model relates to the field of motor rotor testing technology, and more specifically, to a motor rotor dynamic balancing machine that is easy to pick up and put down. Background Technology

[0002] A dynamic balancing machine is a type of balancing machine. It is used to measure the magnitude and location of the imbalance of a rotating object (rotor). The main performance indicators of a dynamic balancing machine are the minimum achievable residual imbalance and the reduction rate of the dynamic balancing machine. The former is the minimum residual imbalance that the balancing machine can achieve on the rotor, and it is an indicator of the balancing machine's maximum balancing capability; the latter is the ratio of the reduction in imbalance after one correction to the initial imbalance.

[0003] Currently, any imbalance in the existing rotor will cause fluctuations in the air gap between the motor rotor and stator, which will affect the smoothness of motor operation and even lead to major equipment accidents. The rotor core is generally made of stacked magnetic steel sheets and has strong magnetism, while the dynamic balancing machine is mostly made of steel. Therefore, there is an attraction between the rotor and the relevant components of the dynamic balancing machine during the dynamic balancing test, which also affects the accuracy of the dynamic balancing test data and the production quality of the rotor.
