Магнитная опора по п. 1, которая имеет измерительное устройство для измерения параметра магнитной связи между статором (3) и ротором (6), на основании которого с помощью устройства (10) управления может снижаться относительная скорость между статором и ротором.4. Магнитная опора по одному из пп. 1-3, при этом ротор (6) выполнен с зубцами, так что на поверхности ротора имеются каналы охлаждения.5. Магнитная опора по одному из пп. 1 - 3, при этом катушки электромагнитов статора (3) соединены по меньшей мере с �1. A magnetic support (9), including a stator (3), which has electromagnets, a rotor (6), which rotates at a certain speed in the stator (3) or around the stator, and - a control device (10) for adjusting the stator electromagnets (3) so that the rotor (6) is mounted on a magnetic support in the stator (3) or on the stator, while it is possible to control the stator electromagnets (3) using the control device (10) so that the they rotated the magnetic field, essentially, with the same speed as the rotor (6), exl which means that some of the stator electromagnets serve to compensate for the rotor's weight, while other stator electromagnets serve to position the rotor, and the stator electromagnets (3) are used to compensate for the weight, connected to the first current rectifier, and the stator electromagnets for positioning the rotor a second current rectifier, while the second current rectifier has a higher regulation accuracy than the first rectifier. 2. A magnetic support according to claim 1, having a synchro sensor, with which it is possible for the control device (10) to determine the rotor speed (6) .3. A magnetic support according to claim 1, which has a measuring device for measuring a magnetic coupling parameter between the stator (3) and the rotor (6), based on which the relative speed between the stator and the rotor can be reduced with the help of the control device (10). 4. Magnetic support according to one of paragraphs. 1-3, while the rotor (6) is made with teeth, so that there are cooling channels on the surface of the rotor. 5. Magnetic support according to one of paragraphs. 1 to 3, while the stator electromagnet coils (3) are connected to at least �
