Offers Reliable Damping and Accurate Performance
A stepper motor operated at its natural frequency may experience excessive settling time, vibration and acoustic noise. A Ferrofluidic damper relies on ferrofluid to absorb the motion energy by a shearing effect which produces a torque that opposes the unwanted oscillatory motion. A Ferrofluidic damper is hermetically sealed and has a non-magnetic housing that attaches to the motor shaft. Inside the housing is an inertial mass which levitates on Ferrotec’s ferrofluid, thus eliminating the need for bearings to support the mass.
A Ferrofluidics damper offers reliable damping and accurate performance with no losses in speed or accuracy, and no reduction in torque. Other performance benefits include:
- Increased positional accuracy
- Reduced settling time
- Reduced torsional oscillations
A Ferrofluidic inertia damper is easily attached to the motor shaft and has no maintenance requirements. It can be custom tuned to your system for optimum results. Typical applications include X-Y-Z Plotters, Printers, Optical Scanners, Robotics and Milling Machines.
A range of sizes and damping coefficients is available.
