Beschreibung
Zusammenfassung:	A radial load of a drive shaft is supported by only a plurality of bearingless motors. Maximum values of the radial load acting on the plurality of bearingless motors are not uniform. The bearingless motor, the maximum value of the radial load acting on which is the largest, has a greater maximum value of supporting magnetic flux generated to generate an electromagnetic force for supporting the radial load, compared with the bearingless motor, the maximum value of the radial load acting on which is the smallest. This configuration allows a reduction in size of a rotary system including a load and a drive shaft in an electric motor system.
