20110181140 | Apparatus Having a Stator and a Rotor Mounted in Said Stator - A stator has a first bearing for a first end of a shaft of the rotor, and a second bearing for a second end of the shaft. The first and the second bearings have a respective permanent magnet which exerts a magnetic force on the shaft. Alternatively, the shaft is in the form of a permanent magnet and the first and the second bearing have a respective ferromagnetic part. At least one of the two ends of the shaft is supported axially by means of a point bearing. The apparatus is, for example, a fan. | 07-28-2011 |
20110146966 | Cooling Device - The cooling device has a fan having a fan wheel, and a heat sink, through which there is a flow for cooling purposes when the fan wheel rotates. The heat sink has guide vanes deviating from the radial direction and is embodied as an integral shaped part. In particular, the guide vanes are embodied in spiral fashion. The cooling device serves, in particular, for cooling an LED lamp. | 06-23-2011 |
20100102665 | BRUSHLESS DC ELECTRIC MOTOR - The brushless DC electric motor comprises, a rotor including a shaft and a permanent magnet fixed on said rotor shaft, stator including a winding in the shape of a hollow cylinder and composed of a plurality of rhombic single coils made of flat wire. The single coils overlap each other in an imbricated manner, wherein the single coils are performed to form an offset at least in the region of two opposite corners. The winding have legs, wherein half of the legs are located in a first radius and half of the legs are located in a second radius. The motor further comprises a housing having two end plates and supporting said rotor and stator. | 04-29-2010 |
20080292947 | Device for energy supply - The apparatus has a carrier for accommodating a plurality of series-connected energy cells, which each have a positive terminal and a negative terminal. An electrical contact is provided in the carrier for each terminal, which electrical contacts, when the energy cell is inserted, connect said energy cell to connection points for drawing energy. Each positive terminal and in each case the associated negative terminal are electrically connected to one another via a switch. These switches are designed such that they are in each case interrupted when an energy cell is inserted. The invention then also makes possible current consumption if fewer than the maximum possible number of energy cells are available. | 11-27-2008 |
