Abstract
The paper is based on the presentation of active magnetic bearings (AMB) which, in the world of technology, more and more overtake a leading position. AMB are increasingly used in all areas in which we have a rotation of one element in relation to others. Special emphasis is placed on integrating AMB in the production process, primarily the possibility of using these bearings on assembly lines and machine tools. Various manufacturing processes require very high accuracy and almost minimal vibration during transportation of products at production line. The automotive industry is such an example. Anywhere welding is performed, such as, during transportation of a car at assembly line, AMB can contribute to increase accuracy, reduce maintenance costs and increase lifetime of bearings. AMB have almost unlimited lifetime, which would mean that the manufacturing process can work almost without stopping. We know that we must stop the production when replacing the classic rotating bearings. From the main spindle bearings of machine tools is required less tolerance and vibration, but for classic roller bearings today is very difficult to fulfill that requirements. Therefore, designers are increasingly deciding to use AMB.
