The Principle of Operation of the Magnetic Bearing

A Magnetic Bearing is an electro magnetic device, which maintains the relative position of a rotating assembly (rotor) with respect to a stationary part (stator). The electro magnetic forces implemented for this are controlled by an electronic control cabinet. An active Magnetic Bearing is, therefore, made up of three distinct parts:

• the bearing itself
• the electronic control system
• the auxiliary bearings (known as RDS, Rotor Delevitation System).
