Technical classification of vibration controllers: differences between active and passive

Vibration controllers are divided into active and passive types according to their principles: active vibration controllers monitor vibration in real time through sensors and compensate in reverse, suitable for ultra-low frequency (<10Hz) and high-precision scenarios; Passive vibration controllers rely on material damping to attenuate vibrations, with low cost and simple maintenance, suitable for isolation at medium to high frequencies (>10Hz).

When selecting, it is necessary to make a comprehensive judgment based on the equipment vibration frequency, load weight, and accuracy requirements, and choose the appropriate type of vibration controller.

Ultra low frequency scenario: The six degree of freedom decoupling advantage of VCM-D600 vibration controller

In heavy-duty confocal microscopes or nanoprocessing equipment, the environmental vibration frequency is often below 5Hz, and traditional isolators are difficult to effectively suppress.

LeadTop's VCM-D600 active isolation strip, as a professional vibration controller, uses six degrees of freedom decoupling compensation technology to control the lateral to longitudinal ratio error within<0.5%, isolation efficiency>95% @ 10Hz, and 20ms response speed to quickly counteract sudden vibrations.

Its 500-600kg load-bearing capacity and dynamic load correction function make it the preferred vibration controller for ultra-low frequency vibration control in the field of precision manufacturing.

Mid to high frequency scenario: Balancing damping and convenience of POT-G series vibration controllers

Microscopes, optical detection equipment, etc. are sensitive to mid to high frequency vibrations (10-100Hz), but do not require ultra-low frequency control. LeadTop's POT-G series rubber isolators, as passive vibration controllers, adopt a hollow cone structure with a natural frequency of 4-8Hz and a damping ratio of 0.2-0.3, which can effectively shorten the recovery period and reduce the resonance peak.

The product supports load adjustment of 50-700kg, equipped with precision horizontal adjustment feet and optional casters, balancing stability and mobility, making it a cost-effective vibration controller for medium and high-frequency vibration control scenarios.

Summary: The selection of vibration controllers should take into account both performance and cost

The core goal of a vibration controller is to achieve a balance between "vibration isolation" and "cost optimization". LeadTop covers the full range of requirements from nanometrology to optical manufacturing through the combination of active VCM-D600 and passive POT-G series.

Users can choose the most suitable vibration controller solution based on the device's vibration characteristics, budget, and installation space, achieving maximum accuracy improvement with minimal investment.
