    摘要: The invention relates to a method for adjusting the speed range of an electric motor, comprising the following steps: - carrying out a number of measurements of a measurement variable, which is indicative of an electromotive force of the electric motor, within a predefined period of time; - determining the number (Zsum) of measurements carried out within the predefined period of time; and - adjusting a maximum allowable rotational speed (Nmax) of the electric motor as a function of the determined amount (Zsum) of measurements.

    摘要: The invention relates to a flat screen to be installed in a household appliance, comprising an LCD matrix display element (1-8) which has a liquid crystal layer (6) enclosed between a front pane on the observer side (1) and a rear pane (2) and is surrounded on the narrow sides thereof by a metallic enclosure (7, 12, 22), and a cover pane (18) arranged in front of the LCD matrix display element (1-8) and carrying an electrically conductive layer (13). The conductive layer (13) is in conductive contact with the enclosure (7, 12, 22). The enclosure (7, 12, 22) extends towards the front (8) beyond the conductive layer (13).

    摘要: A method for starting an electric motor having a rotor, comprising the following steps: —driving the rotor with a first torque in a first rotational direction, wherein a maximum value of the first torque is not higher than a maximum countertorque acting counter to the rotation of the rotor, so that the rotor comes to a standstill in a first stationary position; —driving the rotor starting from the first stationary position in a second rotational direction that is counter to the first rotational direction until the rotor comes to a standstill in a predefined second stationary position; and —starting from the rotor in the first rotational direction starting from the second stationary position.

    摘要: The invention relates to a flat screen comprising an LCD matrix display element (1-7) which has a liquid crystal layer (6) enclosed between a front pane on the observer side (1) and a rear pane (2). Two metallic surfaces (12; 23; 25; 32) which are located opposite each other in the direction of the observer and are conductively connected to each other are arranged upstream of the LCD matrix display element (1-7) in the direction of the observer and comprise overlapping openings through which the LCD matrix display element (1-7) is visible.
