| 20120133229 | ELECTRIC DEVICE ROTOR AND METHODS FOR MANUFACTURE | 05-31-2012 |
| 20110316468 | HYBRID MACHINE COMPRISING A SYNCHRONOUS MOTOR AND AN ASYNCHRONOUS MOTOR - A rotating electrical machine to be connected to a polyphase power grid, having: a polyphase synchronous motor including a rotor with permanent magnets and a polyphase asynchronous motor axially coupled together, and a switching system arranged so as to electrically connect the asynchronous motor to the grid during the machine starting phase in order to bring the synchronous motor to a speed that enables the motor to operate while connected directly to the grid, and to electrically connect the synchronous motor to the grid during a subsequent phase. | 12-29-2011 |
| 20110175468 | ELECTRIC ROTATING MACHINE - An electric rotating machine including a rotor rotating relative to a stator, the rotor rotating a first fan placed at a first end of the stator, and a second fan placed at a second end of the stator opposite to the first end, the first and second fans being configured to generate an air flow from the first fan to the second fan through the rotor and the stator, the first fan comprising an external ring connecting the radial ends of blades together. | 07-21-2011 |
| 20110121668 | PERMANENT MAGNET ROTOR, AND ROTATING MACHINE COMPRISING SUCH A ROTOR - A rotor for rotating an electric machine having permanent magnets and flux concentration, including a shaft extending along the rotational axis of the rotor, a rotor body placed on the shaft, the rotor body having a central opening for the mounting thereof on the shaft; radially oriented recesses wherein the permanent magnets are placed; and in at least one angular space separating two consecutive recesses, at least one cavity leading neither to the central opening nor to the two consecutive recesses, the cavity or cavities located in the space occupying an angular area around the rotational axis of the rotor greater than or equal to half of the angular area of the space. | 05-26-2011 |
| 20110037330 | ELECTRIC MACHINE INCLUDING A MULTI-CHANNEL FAN - The present invention relates to an open rotary electric machine having a rotor mounted to rotate relative to at least one stator and co-operating with the stator to define at least one airgap, the rotor being suitable for rotating at least one fan having at least two channels, said fan including a first channel generating a first cooling air stream passing through the stator, and a second channel generating a second cooling air stream passing through the rotor, the fan including a solid web separating the first and second air streams. | 02-17-2011 |
| 20110001372 | ROTORS FOR ELECTRIC ROTARY MACHINES - The present invention provides a rotor for a rotary electric machine, the rotor extending along a longitudinal axis and comprising: | 01-06-2011 |
| 20100207465 | STATOR FOR ROTARY ELECTRIC MACHINE - A stator for a rotary electric machine, the stator including a jacket and a stack of stator laminations placed inside the jacket, subassemblies of laminations of the stack having extensions with flow channels for passing a cooling fluid therethrough, the subassemblies being disposed in such a manner that fluid flowing along the stack is subjected to a succession of passes within the channels and of passes through wide zones extending between the channels, the stack laminations being arranged in such a manner that for at least one extension, and better for the majority, or even all of the extensions of a subassembly, the flow section made available to the flow of cooling fluid within the extension is greater than the flow section defined by the space extending radially between the extensions and the jacket. | 08-19-2010 |
| 20100200338 | ELECTRIC MOTOR - A motor provided with a secondary driving system including: a casing; a dented wheel permanently rotating during the normal operation of the motor together with the rotor inside the casing; an endless screw that can be brought into a clutch engagement position in which the screw meshes with the dented wheel and in which the rotation of the screw drives the dented wheel in a non-reversible manner and that can be removed from said position in order to allow the normal operation of the motor; a driving member for manually rotating the endless screw, the driving member rotating about the same rotation axis as the endless screw and rotating the latter by direct engagement | 08-12-2010 |
