20120268049 | System for Driving Elongated Electric Machines - Complete drive system, called motor-drive unit, for use in remote locations with limited radial space like downhole, narrow tunnels, pipelines and other applications with similar conditions. Given the spatial limitations the unit must have elongated shape. It includes a number of motors connected mechanically in series and a lower number of inverters, driving groups of the motors so that load is equally distributed along axis of the unit. Motors within each group can be electrically connected in series or in parallel. The motor-drive unit is supposed to be fed by DC voltage via a cable with length up to several km; therefore, it includes a buck converter for stabilization of voltage inside the unit and a power-line communication module to be controllable from the surface. | 10-25-2012 |
20120267971 | Electrical Machine, Rotor for Such Machine and a Method for Its Manufacturing - The purpose is to accommodate large axial channels in a slim electric machine without sacrificing its torque density and radial dimensions. This is possible with a rotor ( | 10-25-2012 |
20110309805 | METHOD FOR OPERATING A DOUBLY FED PERMANENT MAGNET SYNCHRONOUS MACHINE, AND A SYSTEM COMPRISING SUCH A MACHINE AND A CONVERTER - A method for operating a doubly fed permanent magnet synchronous machine and a system including such a machine and a converter for feeding and withdrawal of power. The machine has two or more winding groups where at least one winding group is connected directly to a grid and at least one winding group has the possibility to be connected to the grid via a power electronics converter or directly. | 12-22-2011 |
20110241453 | ELECTRICAL MACHINE AND METHOD FOR THE MANUFACTURE OF STATOR SECTIONS THEREFOR - Electrical machine with a rotor with magnets carried by an annular carrier, in which a magnetic field is created over an air gap between two rotor parts, at which an ironless stator with windings is arranged. A space saving machine is achieved with a stator which is assembled of sections with channels for circulation of coolant, and which has windings with an annular, compact central part providing the active part of the stator. A method for manufacturing stator sections for such electrical machines is described, where a winding is embedded in an electrically insulating casting material for providing a rigid element. A coil is arranged in one part of a bisected shell housing or a bisected casting mold, and the shell housing or mould is closed, casting material is introduced through an opening and the inner part of the housing or mould is subject to underpressure and possibly vibration. | 10-06-2011 |
