Planar Ferrofluid Bearings: Modelling and Design Principles

A ferrofluid is a fluid with paramagnetic properties while having a colloidal stability. This can be used to obtain a hydrostatic type of bearing that distinguishes itself from other bearings by its compactness, inherent stability, low (viscous) friction, absence of pumps and absence of stick-slip. These properties, together with its low price,...
