Winding Arrangement For A Three-Phase Machine

Abstract: A three-phase machine with a 2-pole stator (10) formed with a winding arrangement of a double-layer tooth-wound coil winding has m winding phases (U, V, W). The winding arrangement has at least one first double-layer tooth-wound coil (20) and one second double-layer tooth-wound coil (30). Each tooth-wound coil occupies a half of each of four respective adjacent slots (N) of the stator (10) with a winding phase (W). Each double-layer tooth-wound coil (20, 30) forms two concentrically arranged coils. The second double-layer tooth-wound coil (30) is arranged such that it is shifted by a pole pitch with respect to the first double-layer tooth-wound coil (20).

Impeller for a radial fan

Abstract: The radial fan impeller (1) has a number of circumferentially distributed blades (2) which on the inlet side (16) over their radial extent to the outlet section (6) are connected to a shroud disc (20) which has a central inlet opening (22) running into the inner inlet section (4) of the impeller. Radially shorter intermediate blades (28) are connected to the shroud disc and installed in regions between adjacent blades and from the outer circumference of the shroud disc extend only over a part of the radial extent of the shroud disc and end at a radial distance from the hub (24).

Verfahren zur Regelung eines Gasgemisches unter Nutzung eines Gassensors und eines Gasgemischsensors

Abstract: Die Erfindung betrifft ein Verfahren zur Regelung eines Gasgemisches (8, 107) gebildet aus einem Gas (2, 104) und einem Brenngas (1, 103) bei einem brenngasbetriebenen Heizgerat, wobei das Gasgemisch erzeugt wird, indem uber ein erstes Stellglied (4, 108) eine Gasmenge und uber ein zweites Stellglied (3, 102) eine Brenngasmenge bereitgestellt und gemischt werden, wobei ein mikrothermischer Gassensor (7, 105) und ein Gasgemischsensor verwendet werden und Sensorsignale an ein Steuergerat (10, 112) ubermittelt, und wobei bei einer Anderung des erfassten Sensorsignals ein Gassensor das neu erfasste Sensorsignal des Gassensors mit labortechnisch gemessenen und in einer Wertetabelle im Steuergerat (10, 112) hinterlegten Vergleichswerten verglichen und daraus ein Sollwert des Sensorsignal des Gasgemischsensors (10, 106, 109) bestimmt wird, ohne dass ein Mischungsverhaltnis des Gasgemisches (9, 108) aus Brenngas und Gas verandert wird.

Assembly for the vibration free fixation of an electrical motor bearing

Abstract: Die vorliegende Erfindung betrifft eine Anordnung zur schwingungsisolierenden Lagerung eines Elektromotors (5) an einem Halteteil uber mindestens ein umfangsgemas zwischen Elektromotor (5) und Halteteil (3) angeordnetes Isolationselement (4). The present invention relates to an arrangement for the vibration-isolating mounting of an electric motor (5) on a holding part via at least one circumferentially between the electric motor (5) and retaining member (3) disposed insulating member (4). Dieses Isolationselement (4) bewirkt eine erste Eigenfrequenz der Drehschwingung des Gesamtsystems, die kleiner, insbesondere deutlich kleiner ist, als die erste Anregungsfrequenz des Elektromotors (5). This insulation element (4) causes a first natural frequency of the torsional vibration of the overall system, which is smaller, particularly significantly smaller, than the first excitation frequency of the electric motor (5).

Electric motor having improved motor cooling for driving a fan

Abstract: The disclosure relates to an electric motor, in particular configured as an internal rotor motor, for driving a fan having a stator, a rotor, a drive shaft, motor electronics disposed on a first axial side of the stator, a first cooling impeller which is associated with the motor electronics and disposed on the first axial side of the stator on the drive shaft and generates a first cooling air flow at least to the motor electronics during operation of the electric motor, and a second cooling impeller which is disposed immediately adjacent the stator on a second axial side of the stator opposite the first axial side and has impeller blades that generate a second cooling air flow at least in the axial direction along the stator during operation of the electric motor.
