20080258583 | Electric Machine Comprising a Claw-Pole Stator and Claw-Pole Stator Metal Sheet - The invention relates to an electric machine comprising a rotor, a claw-pole stator ( | 10-23-2008 |
20090252607 | FLUID PUMP AND METHOD FOR PRODUCING A FLUID PUMP - The invention relates to a fluid pump, in particular a liquid pump for a cooling and/or heating circuit of a motor vehicle, having a pump housing and having a rotationally fixed shaft, which is arranged in the pump housing, for an inner rotor which has an impeller wheel. According to the invention, it is proposed that the shaft is mounted at one side and, at its end remote from the bearing point, supports a bearing cap which engages at least partially around the shaft. The invention also relates to a method for producing a fluid pump of said type, in which method the shaft is fixed with its first end in a housing, in particular in a plastic housing, of the pump, the inner rotor of the pump is pushed onto the shaft and is secured axially by means of a bearing cap which is placed onto the shaft and is supported by the shaft. | 10-08-2009 |
20120007456 | ELECTRONICALLY COMMUTATED ELECTRIC MACHINE - The invention relates to an electronically commutated electric machine ( | 01-12-2012 |
20120091839 | ELECTRIC MOTOR - The invention relates to an electric motor, in particular for a pump in a motor vehicle. The electric motor has a housing, a stator and an armature. The electric motor also has a control unit which is preferably formed on a printed circuit board, wherein the printed circuit board is connected to the housing and/or to the stator via electrical connecting lines which are in particular in the form of wires and are solid. According to the invention, in the electric motor, the connecting points which each connect one connecting line to the printed circuit board are arranged together on one printed circuit board surface of the printed circuit board, on a contact area which is smaller than the printed circuit board area, such that mechanical deformation effects to the printed circuit board caused by temperature fluctuations and/or vibration at the connecting points are reduced to a minimum, or at least in comparison to an arrangement which is distributed in particular uniformly over the printed circuit board surface. | 04-19-2012 |
