A rotor for a rotary electric machine has permanent magnets defining magnetic poles of the rotor, i.e. a first pole and a second pole adjacent to the first pole, the first and second poles having different polarities; permanent magnets assigned to the first pole contribute only to the polarity of the first pole, and at least one shared permanent magnet contributes in part to the polarity of the first pole and in part to the polarity of the second pole.

The invention relates to an electrically insulated conductive wire comprising an electrically conductive core and an insulating structure that covers the core and comprises at least: one layer of a first electric insulation material; and one layer of a second electric insulation material. The first electric insulation material layer and the second electric insulation material layer are separated by at least one layer of a third electric insulation material that is different from the first and second electric insulation materials. At least one of the first electric insulation material and second electric insulation material layers is located inside the insulating structure. The first electric insulation material and the second electric insulation material comprise polyesterimide and/or polyester.


The present invention relates to a brake (20) for an electric motor (10), comprising: a yoke, at least one brake disc intended for being rotated with the shaft of the electric motor, at least one armature axially movable relative to the yoke between a braking position in which said armature is applied against the brake disc and an inactive position at a distance from the brake disc, at least one retaining element (50) axially movable with the armature, at least one spring tending to maintain the armature in braking position, an electromagnet biasing the armature into the inactive position when supplied with current, and a system for locking the armature in the inactive position, the locking system comprising a locking member (70) movable between a locked position in which said member engages with the retaining element (50) such as to retain the armature in inactive position against the return action of the spring and an unlocked position for releasing the armature allowing the armature to be returned into the braking position, the retaining element (50) comprising a rod (51) sliding in the yoke, the locking member (70) being rotatable about an axis of rotation parallel to that of the motor, the brake comprising an electrical actuator making it possible to move the locking member.

A system for controlling and regulating a generating set including an alternator that is mechanically coupled to a drive motor, the alternator including a terminal box borne by a casing and containing electric connections connected to the windings of the alternator. The system includes a controller part for controlling the motor of the generating set and a regulator part for regulating an output voltage of the alternator, the voltage regulator part being positioned outside the terminal box and solidly connected to the controller part of the set.


Motorized system for holding and driving at least one solar energy collector, said system including: a supporting structure for the panel, movable at least in part in relation to the ground, so as to allow controlled displacement of the collector, notably about at least two axes of rotation, at least one blocking member, fixed in relation to the ground, at least one coupling member, movable with the collector and adapted to cooperate with the blocking element in at least one locking position of the collector, in order to hold the collector in the event of extreme winds, the coupling member being able to be moved into the locking position or locking positions as a result of a predefined movement of the collector, from a usual operating position where the coupling member is remote from the blocking member.

The invention relates to an electric machine comprising a stator, this stator comprising a set (10) of magnetic laminations which is made up of at least one first subset (50) and of at least one second subset (60) adjacent to the first the laminations of the first and second subsets having parts which become superposed, each comprising at least one closed channel formed within the laminations, the laminations being identical but angularly offset from one another by an angle 360/n about the axis of the machine, where n is a non-zero integer, the laminations being without symmetry in a rotation by 360/n so that the parts of the laminations thus offset which become superposed are nonidentical and create the said perturbation in the flow at the transition between the channels of the first and second subsets.


The present invention relates to a rotating electrical machine including at least one stator and at least two rotors, which are arranged on either side of the stator along an axis of rotation of the machine,
