Abstract: A hybrid electric machine includes N phases (N?1), each phase having first and second assemblies movable relative to one another and each having a set of teeth made up of a number of teeth that are equally distributed according to a plurality of periods, in which: a. the first assembly is made up of two magnetized parts, each including a magnet magnetically coupled with two toothed yokes, the magnet of one of the magnetized parts being polarized along the same axis but in the opposite direction to the polarization of the magnet of the second magnetized part; b. the second assembly including at least two toothed zones with pitches identical to the pitch of the toothed yokes; c. one of the assemblies has at least two sets of teeth in phase, and the other assembly has at least two sets of teeth which are out of phase by a half-period.

Abstract: The invention relates to an electric motor including a rotor (2) including a magnetised part (3) defining a plurality of rotor poles, and a stator (4) including a plurality of coils (8) and a magnetic armature (6) defining a magnetic circuit. Each coil comprises a coil core (14) in the form of an attached part made of a magnetic material fastened to the magnetic armature, the coil core including a tooth defining a magnetic pole of the stator. The tooth comprises extensions (6a, 16b) extending in an axial direction, a height H? of the tooth and a height H of the coil being comparable to a height H? of the magnetised part of the rotor.

Abstract: A hydraulic control valve system comprising a hydraulic valve block with a plurality of control valve segments arranged in a juxtaposed manner, each control valve segment comprising a first line, for example a pump line, a second line, for example a return line, and a displaceable valve rod adapted to open and close the first line, respectively close and open the second line to varying degrees depending on a position of the valve rod. The valve system further has a plurality of actuators arranged in a juxtaposed manner, one actuator for each valve segment, each actuator comprising an electrical motor connected to a respective said valve rod through a coupling mechanism.
