Description

Technical Field

[0002] The motor rotor is affected by materials, manufacturing processes and assembly processes during its manufacturing process, resulting in an initial imbalance. Based on this, after the motor rotor is processed, workers usually test and correct the imbalance of the motor rotor to ensure product quality.

[0003] The existing balance detection mechanism usually includes two detection components, which are respectively carried at the two ends of the rotor and used to detect the imbalance of the rotor. When facing rotors of different specifications, it is necessary to adjust the positions of the two detection components so that the distance between the two detection components matches the corresponding rotor. In the prior art, the distance between the two detection components is generally determined by experienced workers through visual inspection. However, the distance determined by visual inspection will inevitably have errors, resulting in the inability of the two detection components to be accurately carried at both ends of the rotor and detect the imbalance of the rotor, which greatly reduces the detection efficiency of the rotor.
