Background

The motor rotor is used as a core rotating component for realizing electromechanical energy conversion of the motor, and the running state of the motor rotor directly determines the overall performance of the motor. In the high-speed rotation process, if the rotor has uneven mass distribution due to material defects, processing errors or assembly deviation, periodic centrifugal force can be generated to cause vibration, noise and even damage to components, and the dynamic balance test of the motor rotor is a key technical means for solving the problem. From the definition, the method is based on the principle of rotor dynamics, detects parameters such as vibration amplitude, phase and the like when a rotor rotates through professional equipment such as a dynamic balancing machine and the like, accurately positions the position of mass unbalance and quantifies the unbalance amount, ensures stable operation of the motor at a rated rotation speed, has the test meaning of penetrating through the whole life cycle of the motor, and has the primary value of ensuring the operation stability and the operation precision of the motor, and secondly, can obviously prolong the service lives of the motor and related parts. In the aspect of energy efficiency, dynamic balance test is an important way for reducing energy consumption. Vibration caused by rotor imbalance produces additional mechanical losses, resulting in reduced motor efficiency, while it is critical to noise control. The periodic vibration of the unbalanced rotor can be transmitted through the shell to form high-frequency noise, so that the user experience of civil equipment such as air conditioners, washing machines and the like is affected, the hearing health of operators in industrial workshops is also endangered, and finally, from the perspective of safe production, dynamic balance testing is the key for preventing major accidents. For high-speed rotating motors such as turbo generators, large fans and the like, the overlarge unbalance amount can lead to bending of a rotating shaft and breakage of a rotor, and even cause a galloping accident;

The measuring of external vibration to the rotor can be reduced or isolated, the rotor is supported in a non-fixed mode, the influence of fixed force on the rotation of the rotor can be reduced, and the accuracy in dynamic balance is improved. The eccentric influence exerted on the rotor by the motor in a direct connection mode can be reduced by driving the rotor through the belt. The rotor is directly clamped and fixed after the rotor test is finished through the rotor clamp, so that the problem of positioning deviation of unbalance points after the rotor moves is avoided;

According to the technical scheme, although the measurement of external vibration on the rotor can be reduced or isolated, the rotor is supported in a non-fixed mode, the influence of the fixing force on the rotation of the rotor is reduced, and the accuracy in dynamic balance test is improved, the rotor clamp directly clamps and fixes the rotor after the rotor test is completed, so that the position of the rotor is difficult to change, the clamped rotor cannot be subjected to turning and milling at any position, the position of a turning and milling unbalanced point is not accurate enough, the coverage is insufficient, and further the dynamic balance re-inspection still has an unbalanced point, so that the detection effect and efficiency are influenced;
