Small Vibrators, Modal Exciters

YMC VT series Permanent Magnetic VibrationVibrators is the high–quality, compact machine with a permanent magnetic field. Be designed for long, trouble–free operation, and has a force rating of from 10N to 1000N enabling relatively heavy loads to be excited to high g levels. The moving element is supported by a robust rectilinear guidance system consisting of grouped radial and transverse flexures in a unique construction. The flexures are made from a bonded sandwich of spring steel and a damping elastomer, providing a clean acceleration waveform with low cross motion and low distortion characteristics.
