Overview

YMC MS-20 Modal Shaker Kit

The YMC MS Series Modal Shakers are engineered for high-performance modal testing and vibration analysis applications. Built with permanent magnet technology, these shakers deliver precise, stable, and reliable excitation for a wide range of experimental scenarios.

Designed with high-quality materials, rugged construction, and stringent quality control, the MS Series ensures long-term durability and consistent performance. With an optimized force-to-weight ratio, these shakers provide efficient excitation while minimizing setup complexity and time.

The MS-20 model is a compact, lightweight permanent-magnet shaker delivering ≥20 N peak force across a DC – 6 kHz frequency range — ideal for general mechanical mobility measurements, experimental modal analysis (EMA) and structural dynamics investigations on small to medium structures.
