Bearingless motor
A bearingless motor is a combination of a magnetic bearing and an electric motor . The term bearingless is intended to indicate that no mechanical roller or plain bearings are used. The radial stabilization of the rotating motor shaft is completely contactless with the help of active magnetic forces. In contrast to a conventional drive with magnetic bearings, the motor and magnetic bearing components are combined in a bearingless motor. The bearing winding and the motor winding are integrated either as combined or separate winding systems in a common sheet metal section, which means that very compact magnetic bearing drive systems can be implemented.
In addition to the typical areas of application for magnetic bearings, they are also often used in the field of hermetically sealed pumps.
