Description

Technical Field

[0001] The utility model belongs to the technical field of testing devices and relates to a fan motor rotor dynamic balance testing device. Background Art

[0002] The motor dynamic balancing test is a test for the dynamic balance of the motor rotor. It is an important step to ensure the stable operation of the motor and reduce vibration. The imbalance of the rotor can be determined by analyzing the vibration data. These imbalances may come from the manufacturing errors of the rotor itself, or they may be caused by the wear of impurities attached to the rotor. According to the imbalance obtained by the test, the mass can be increased or decreased on the rotor to offset the imbalance. The existing balancing test device places the rotor on a fixed operating table for rotation and vibration detection, but in order to facilitate installation and observation of the rotor, it is placed directly on the operating table. In this way, when the rotor is tested, it will rotate or vibrate excessively and burst out, causing collision with equipment or personnel, thereby increasing the danger and delaying the test results. Therefore, in view of the above problems, a fan motor rotor dynamic balancing test device is proposed. Utility Model Content
