Abstract: The invention relates to an aircraft thruster (30) comprising at least a first propeller (32) provided with a plurality of radial blades (34) extending about an axis (A) of rotation of the said first propeller (32), which is driven in rotation by a first electric motor (36), the electrical supply means of which comprise power circuits (42) carried by a fairing of the thruster characterised in that the power circuits (42) are arranged in an annular manner in an annular part (40) integral with the fairing of the thruster (30), this annular part (40) being arranged around the said first propeller (32).

Abstract: An assembly including a winding and a cooler in contact with conductors of the winding, the cooler including a container forming a heat dissipator and including a phase change material having the ability to absorb a surplus quantity of heat when the conductors of the winding are subject to an increase in their current density and the heat dissipator is composed of at least two hollow parts separate and nestable with one another and intended to house the phase change material.
