Tips: What causes vibration or resonance in a servo motor at low speed?
Low-speed vibration or resonance in a servo motor is usually caused by improper servo gain tuning, load inertia mismatch, mechanical instability, or encoder feedback interference. When the position loop, speed loop, or current loop parameters in the servo drive are set too aggressively, the AC servo motor may continuously overcorrect during low-speed operation, creating oscillation, shaking, or resonance. Mechanical factors such as loose couplings, weak mounting structures, shaft misalignment, worn bearings, or insufficient system rigidity can also amplify vibration frequencies. In addition, unstable power supply, electrical noise, or incorrect encoder signals may affect servo motor feedback accuracy and lead to jitter or unstable motion. Proper PID parameter adjustment, optimized acceleration/deceleration settings, stable motor installation, and high-resolution encoder feedback are commonly used to improve low-speed smoothness and reduce servo motor resonance in industrial automation systems.
