20080197718 | ELECTRICAL MACHINE WITH FERROFLUID COMPONENTS - An electrical machine includes a primary part and a secondary part which are spaced apart from one another by an air gap and capable of moving relative to one another. The primary part and/or the secondary part is/are constructed for generating magnetic or electromagnetic fields, with the primary part and the secondary part having flux-concentrating means for guiding a magnetic main flux. At least portions of the magnetic main flux are guided by a ferrofluid. | 08-21-2008 |
20080296427 | Method for Winding an Electrical Machine, and an Auxiliary Winding Body - In a method for winding an electrical machine, a winding auxiliary body is placed on at least one of the end faces of a base body such as to cover at least one of the slot end openings within a circumferential bridging area. Electrical conductors of a winding system are inserted in at least one of the slots whose slot end opening is on one side of the bridging area and passed through an uncovered slot end opening. Subsequently, the electrical conductors are deflected by the winding auxiliary body and guided to a further uncovered one of the slot end openings on another side of the bridging area. After placement of an end plate having an axially projecting separating element and plugging an axial attachment cutout of the winding auxiliary body onto the separating element, the winding auxiliary body is removed, thereby producing a winding element of the winding system. | 12-04-2008 |
20090127968 | ELECTRICAL MACHINE WITH AN END-SIDE DEFLECTION OF ELECTRICAL CONDUCTORS - Disclosed is an electric machine comprising a rotational shaft and a base that is provided with two axial faces and grooves for accommodating electrical conductors ( | 05-21-2009 |
20130175892 | ELECTRICAL MACHINE WITH TWO AXIAL FANS - An electrical machine includes a stator, a rotor magnetically interacting with the stator, a shaft supported on the stator for rotation in a first direction of rotation and in a second direction of rotation which is opposite to the first direction of rotation, wherein the rotor is arranged on the shaft, a first axial fan mounted on the shaft on a side of the rotor for co-rotation with the shaft in the first direction of rotation and having freewheeling capability on the shaft in the second direction of rotation, and a second axial fan mounted on the shaft on the same side of the rotor as the first axial shaft for co-rotation with the shaft in the second direction of rotation and having freewheeling capability on the shaft in the first direction of rotation. | 07-11-2013 |
20130187512 | SQUIRREL-CAGE ROTOR - A squirrel-cage rotor of an asynchronous machine has a rotor bar ( | 07-25-2013 |
