Abstract: The disclosure relates to a rotor for an electrical machine having internal permanent magnets including a yoke consisting of a stack of sheets defining a plurality of recesses for receiving parallelepipedal permanent magnets, the recesses being surrounded by magnetically saturated external transverse isthmuses, by radial isthmuses, lateral isthmuses and oblique isthmuses, wherein the magnets are assembled in pairs of magnets magnetized in the same direction and perpendicular to the radial direction of the radial isthmuses arranged between the coupled magnets, the radial isthmuses having a thickness of less than 5% of the diameter of the rotor, and the perimeter of the cross section of the rotor is formed by a succession of curved profiles, between two consecutive pairs of magnets, and tangential linear profiles at the external transverse isthmuses. The disclosure also relates to the application of such a rotor for creating a motor, in particular a motor for a turbo compressor, or an electrical generator.

Abstract: The present disclosure relates to a mono- or polyphase electric motor including a stator carrying at least three coils and consisting of 12×N straight teeth extending radially, N being an integer greater than or equal to 1, and of an equal peak divergence alpha, measured at their end from the centre of the motor, and a rotor exhibiting P pairs of magnetized poles such that P=5+2×R, P being a non-multiple of three, R being an integer greater than or equal to 0, alpha lying between 360°(12×N)/3 and 360°(12×N)/2.

Abstract: An electric machine comprises a yoke supporting N toroidal coils and a central rotor comprising a permanent magnet. The yoke has a plurality of stator modules comprising at least one stator core made from a soft ferromagnetic material supporting at least one coil. The stator cores have, at their front ends, complementary coupling surfaces providing magnetic and mechanical continuity. The machine further comprises—a cylindrical outer casing made from a thermally conductive material, —a plurality of continuous and solid longitudinal ribs extending radially and positioned between the cylindrical outer casing and the stator modules, in order to ensure the mechanical positioning of the yoke relative to the outer casing and promote the thermal conduction of heat from the yoke toward the outer casing.
