Under high-speed operation conditions, the torque motor is like a precise "power engine", but the vibration problem generated during its operation is like the noise in a symphony, which not only affects the accuracy of the equipment, but also endangers the operation stability. The dynamic balancing correction technology is the ingenious "tuner".
From the essence of mechanics, high-speed operation causes centrifugal force to be generated in the motor rotor and other parts. When the mass is unevenly distributed, the magnitude and direction of the centrifugal force change with the rotation, causing periodic vibration. Based on this, dynamic balancing correction achieves "force harmony" through precise measurement and compensation. Professional instruments first detect the rotor under high-speed simulation state, capture the vibration amplitude and phase information caused by small mass eccentricity, and construct an imbalance "portrait".
The correction means are divided into weighting and deweighting methods. Weighting is to accurately add mass blocks on the light side, like adding weights to the light end of an unbalanced "seesaw", and calculate the required mass and position based on the imbalance data, so that the synthetic center of mass is close to the rotation axis, so that the centrifugal force is close to zero; deweighting is the opposite, and the appropriate amount of material is removed on the heavy side by milling and drilling. This is just like carving a work of art, with fine operations between millimeters and grams of weight to reshape the ideal mass distribution.
In terms of deep mechanism, the centrifugal force is uniform and symmetrical after correction, which greatly reduces the "cause" of structural resonance. From the vibration transmission path, the vibration is suppressed from spreading to the equipment through the bearing and base to avoid the "amplification effect" of resonance. At the control level, stable operation reduces interference, sensor feedback is more accurate, and the closed-loop control accuracy soars, ensuring that the motor is "as stable as Mount Tai" at high speed, and the positioning accuracy jumps to the micron level.
In short, dynamic balancing correction puts on "shock-absorbing armor" for high-speed torque motors, "intensively cultivates" micro-quality reshaping, macro-mechanical regulation and system coordination, tames vibration, unlocks the potential for efficient and precise operation, and enables high-end manufacturing equipment to "leave the dust behind" on the high-speed track.
