Ferrofluid rotational damper for stepper motors

At resonance frequency, a stepper motor can cause increased settling time, vibrations and noise generation. A Ferrofluidic^® damper works with a Ferrofluid as a damper medium that dissipates vibration energy to heat by viscous drag. Such a damper is hermetically sealed. It has a nonmagneetic housing that is attached to a motor shaft. Inside the housing there is a seismic mass, freely suspended with Ferrofluid. The Ferrofluid couples by viscous drag the mass to the housing.

A Ferrofluidic^® damper is an extremely reliable and precise damping element that causes no loss on the motor torque.

The mounting of a Ferrofluidic^® damper is very easy. It's operation is free of maintenance. It can be adapted to specific requirements. Typical applications are X-Y-Z plotter, printer, optical scanner, robots and small machines.

A variety of sizes is available.
