Abstract: A turbomachine including a rotary body including a motor shaft supplying mechanical power, and at least one magnetic drive pump including at least: one stator delimiting an annular inner space and including a first and a second flange, a rotor arranged in the inner space between the first and second flanges and capable of driving fluid, the rotor being able to rotate about an axis of rotation, a pair of magnets having opposite polarities coaxially arranged on the rotor with the axis of rotation, a magnet arranged on the first flange in order to co-operate with one of the magnets of the pair of magnets of the rotor, a magnetic rotator for rotating the rotor arranged on the second flange, the second flange being non-magnetic.

Abstract: A fuel supply circuit of an aircraft engine includes a centrifugal pump mechanically coupled with an engine shaft delivering mechanical power. The circuit further includes at least one electromagnetic pump including at least one stator delimiting an annular internal volume in which is present a rotor able to drive a fluid, a plurality of magnets annularly distributed on the rotor and at least a plurality of coils annularly distributed inside the stator face-to-face with the magnets. The rotor is connected to the engine shaft by a one-way clutching element.

Abstract: A turbomachine comprises a rotating spool comprising a drive shaft delivering mechanical power. The turbomachine comprises an electromagnetic pump mechanically decoupled from the drive shaft. The electromagnetic pump comprises at least one stator delimiting an annular internal volume in which is present a rotor able to drive a fluid, a plurality of magnets distributed annularly on the rotor and at least one plurality of coils distributed annularly inside the rotor. The coils of the plurality of coils face magnets along an axial direction.
