摘要： The invention relates to a diagonal fan having a housing, an impeller driven by an electric motor whose hub together with an air conduction sleeve surrounding the impeller defines an essentially annular flow channel having an air intake opening and an air exit opening. The hub takes the form of a truncated cone that widens towards the air exit opening, the air conduction sleeve being essentially profiled, the electric motor being held in the housing by means of bridges that essentially extend in a radially outwards direction. The invention is characterized by the fact that the bridges to secure the motor are arranged in the region of the air intake opening of the flow channel.

摘要： A method for preventing a malfunction of a filling device when a container is filled by a user with a beverage. The method includes providing a filling device comprising a control unit which controls the filling device, a camera which takes an image of a container currently being used with the filling device and which outputs the image to a classifier which then uses a trained learning algorithm to analyze the output of the image of the container provided by the camera. The trained learning algorithm of the classifier analyzes which container is currently being used based on characteristics of the container so as to classify the container into a predefined class. The predefined class is then employed by the control unit to prevent the malfunction of the filling device.

摘要： The invention relates to a brushless DC motor having an at least two-pole permanent magnet rotor and an at least two-pole stator whose poles carry an at least single-strand stator winding which can be energized with a current according to the rotor position by means of an electronic commutation device, there being a substantially uniform cylindrical air gap between the rotor and the stator. The rotor is characterized in that at least one stator pole, or a specially provided auxiliary pole having an auxiliary winding, is provided which is energized with a current to start up the motor. In accordance with a preferred embodiment of the invention, the auxiliary winding can additionally be used as a sensor winding to determine the position of the rotor.

摘要： The invention relates to a method for the commutation of a brushless direct current motor in which the position of the rotor in respect of the stator is determined directly or indirectly and an external operating voltage is applied, at a preset commutation angle, to the at least one motor winding depending on the determined rotor position. In accordance with the invention, the motor is preferably switched periodically back and forth between a second optimized commutation angle and the first, original, preset commutation angle. If a change in rotational speed results from switching between the commutation angles, the new operating point deviates from the old operating point. To compensate for this difference in speed, not only is the pre-commutation angle changed but the motor voltage is also changed.
