Abstract
Applications of magnetic liquid technology to damping phenomenon are reviewed. Products utilizing ferrofluids, such as a rotary viscous inertia damper, linear damper, damper/seal assembly, and dashpot are discussed. The rotary dampers are used to enhance stepper motor performance. A magnetic liquid film sheared between a moving and stationary component forms the basis of these devices. The fluid is retained by magnetic forces and does not leak out. Examples of actual use of these dampers on operating systems, along with the test results, are presented.
