    摘要: The invention relates to a steam turbine comprising a rotor (6) which is rotationally mounted in a longitudinal direction (5) and at least one turbine component (14) which is arranged about the rotor (6), said turbine component defining an inner chamber (18) which is impinged upon by inner pressure (p1), in relation to an external chamber (19) which is impinged upon by external pressure (p2). The internal pressure (p1) is different from the external pressure (p2). The steam turbine comprises at least one water-driven shaft bearing component (18) which is used to mount the rotor. The turbine components (4) and the shaft bearing components (8) are arranged in a successive manner and in a longitudinal direction (5) in relation to each other.

    摘要: The invention relates to a method for the automatic determination of the effective mass (meff) of a door system that is driven by a motor and comprises at least one door. According to said method, a modification (ΔV) of the speed that occurs during an acceleration displacement is determined and a force variable, e.g. the motor current or an armature voltage is totalled or integrated during the acceleration displacement. The effective door mass (meff) is determined from the sum or integral of the force variable and the speed modification. The invention also relates to a control unit for the automatic determination of the effective door mass (meff), said unit comprising a memory for force variable profiles. The control unit is designed in such a way that a determination of the mass can be carried out for different force variable profiles in the memory using the same program code.

    摘要: The invention relates to a method for ascertaining a correction value for the angle of the rotor of an electrically commuted reversible synchronous motor relative to a sensor used for the activation thereof. In order to equalize the sensor and recognize and correct electrical incorrect angles and incorrect controls, it is proposed that the motor be activated in a calibration journey using an externally forced rotating field, the electrical angle of the rotating field and the mechanical angle of the rotor, which is measured by the external sensor, be measured simultaneously on at least one reference position during the calibration journey and be stored associated with one another as a measurement series of value pairs, the electrical angle of the rotating field and the mechanical angle of the rotor, which is measured by the sensor, be detected simultaneously after direction reversal of the rotating field and be stored associated with one another as a second measurement series of value pairs, the angle difference between the electrical angle and the mechanical angle be calculated from value pairs of both measurement series which correspond to one another, and the correction value for taking the actual incorrect angle into consideration be calculated from the two angle differences by averaging and be stored.
