20100186592 | Air Cleaners for Electrical Machines - The present invention provides an air cleaner suitable for forced air open-ventilation systems used to cool electrical machines. The air cleaner comprises an air chamber with a first end where air is drawn in from the surroundings, via an inlet, by the open-ventilation system and a second end, opposite the first end, where air is drawn out of the air chamber, via a first outlet, by the open-ventilation system. A rotating means is contained within the air chamber and may be driven to rotate about an axis that extends between the first end and the second end of the chamber. When driven to rotate, the rotating means applies a centrifugal force to any particles contained in the air entering the air chamber and throws them radially outwards from the central axis. These particles are then drawn out of the air chamber, via at least one second outlet formed adjacent to a radially outer edge of the rotating means, by a high-velocity outlet stream of the open-ventilation system. | 07-29-2010 |
20100168877 | Electronic system with component redundancy, and control chain for a motor implementing such system - An electronic system with component redundancy includes a first processing unit, connected to a first board, and a second processing unit redundant with respect to the first unit, and connected to a second board redundant with respect to the first board. Each processing unit and each board include a first communication port, the first communication ports of the first unit and of the first board, and, respectively, of the second unit and of the second board, being interconnected by a wired communication link. Each processing unit and each board include a second communication port, the second port of the first board being connected to the second port of the second unit by a wired communication link, and the second port of the second board being connected to the second port of the first unit by a wired communication link, each communication port able to be activated or deactivated by a corresponding software command. | 07-01-2010 |
20100117476 | ELECTRICAL MACHINES WITH REDUCED COGGING - An electrical machine has at least two separate groups of at least two circumferentially adjacent magnet poles. One of the circumferentially outer magnet poles in one of the groups of magnet poles is defined as being in its reference position. The reference position of each other magnet pole is defined as the position each other magnet pole would occupy if all the magnet poles were equally circumferentially spaced around the first or second body and the one circumferentially outer pole was in its reference position. At least one of the circumferentially outer magnet poles in each group is sited in its reference position. At least one magnet pole in each group is a displaced magnet pole and is sited in a position that is displaced from its reference position by an amount that is not equal to an integral multiple of the reference angular pitch of the winding slots. The displacement of the magnet poles provides a pronounced reduction in cogging. | 05-13-2010 |
