1. A fuel supply circuit of an aircraft engine connecting a fuel reservoir to a combustion chamber of a turbomachine, comprising:
a low-pressure centrifugal pump mechanically coupled with an engine shaft; and
an electromagnetic pump comprising a 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 a plurality of coils annularly distributed inside the stator face-to-face with the plurality of magnets,
wherein the rotor is connected to the engine shaft by a one-way clutching element,
wherein an inlet of the low-pressure centrifugal pump and an inlet of the electromagnetic pump are connected to the fuel reservoir such that the turbomachine can be supplied with fuel by the low-pressure centrifugal pump, by the electromagnetic pump, or by both the low-pressure centrifugal pump and the electromagnetic pump simultaneously, and
wherein the rotor comprises an inner pinion interacting with an outer ring with an inner toothing, the magnets of the plurality of magnets being retained on the inner pinion, the coils of the plurality of coils being face-to-face with the magnets along an axial direction.
