| 20110260566 | ROTATING ELECTRICAL MACHINE - A rotor disc is disclosed for an axial flux permanent magnet rotating electrical machine. The rotor disc ( | 10-27-2011 |
| 20110241460 | AXIAL FLUX MACHINE - An axial flux rotating electrical machine is disclosed, which comprises a stator sandwiched between two rotors. The machine comprises retention means for retaining magnets on the rotor, the retention means comprising a back plate with a plurality of protrusions which define a plurality of pockets for accommodating the magnets. The retention means is arranged such that the magnets can be inserted into the pockets and held therein, and the retention means with inserted magnets can be fixed to a rotor so as to retain the magnets axially and tangentially. A cooling jacket for the stator, and techniques for securing the stator to the machine, are also disclosed. | 10-06-2011 |

| 20100039077 | LOAD ANGLE MEASUREMENT AND POLE SLIP DETECTION - Apparatus for measuring load angle in a synchronous generator is disclosed. The synchronous generator is of a type comprising a main machine, an exciter for exciting the main machine, and a permanent magnet machine for exciting the exciter. The apparatus comprises means for sensing a waveform produced by the permanent magnet machine, means for sensing a waveform produced by the main machine, and means ( | 02-18-2010 |
| 20100013340 | ROTATING ELECTRICAL MACHINE - A rotating electrical machine is disclosed, the machine comprising a stator | 01-21-2010 |
| 20100007313 | METHOD AND APPARATUS FOR CONTROLLING EXCITATION - Excitation control circuitry for a synchronous generator is disclosed. The synchronous generator is of a type comprising a main machine ( | 01-14-2010 |
| 20090096212 | POWER GENERATION SYSTEM - A power generation system is disclosed for supplying power to an electrical grid. The system comprises a synchronous machine and coupling means for coupling the synchronous machine to a prime mover. Control means are provided to control the system such that the system is selectively operable in two modes. In the first mode, the synchronous machine is coupled to the prime mover and acts as a synchronous generator to supply power to the grid. In the second mode the synchronous machine is decoupled from the prime mover and acts as a synchronous condenser. This can allow parameters of the grid, such as power factor and voltage, to be adjusted. | 04-16-2009 |
