摘要： An electric drive comprises a bearingless electric machine (103), a converter (116), and a control device (101). The stator of the electric machine has a cage winding (106) comprising bars connected to a conductor ring. The control device controls the converter to supply torque generating current components to the bars so that torque is generated in accordance with electric machine control and to supply levitation current components to the bars so that the rotor of the bearingless electric machine is levitated in accordance with levitation control. The cage winding allows the currents of the bars to be controlled so that different current sheet distributions can be generated so as to generate desired torque and magnetic force.

摘要： A magnetic actuator comprises interconnected actuator elements (101-104) each comprising a core element (109) that comprises a center tooth section (110), side tooth sections (111, 112) on both sides of the center tooth section, and a yoke section (113) connecting the center and side tooth sections. Each actuator element further com- prises a winding (105) around the center tooth section. The magnetic actuator further comprises permanent magnets (114-117) in gaps between the yoke sections of adjacent ones of the core elements. The direction of magnetization of each of the permanent magnets is across the gap where the permanent magnet is located. As there are three teeth in each core element, decoupling is achieved so that magnetic flux caused by electric current in one actuator element does not significantly flow to other actuator elements. The permanent magnets generate bias magnetic fluxes which make the operation of the magnetic actuator more linear.
