摘要： In a displacement drive that provides an obstruction prevention function for movable parts, in particular such as windows and sunroofs in motor vehicles, a decrease in the rotation speed or velocity of the drive is provided in order to achieve a predefined spring rate in specific displacement ranges so as to lower the kinetic energy. Within the predefined range before the closed position is reached, the rotation speed and/or the output of the drive is reduced linearly. The reduction to a minimum rotation speed or minimum output takes place within a specific position range. The minimum rotation speed or minimum output is reached at a specific position before the closed position and is substantially constant. Corresponding to different supply output levels, a linear reduction, for example, is performed along lines of different slopes, the length of the specific position range in which the reduction is performed being constant.

摘要： An arrangement for the determination of the temperature of a direct-current motor. The temperature is determined in an indirect manner from the temperature-dependent armature resistance, with the armature resistance being determined as the quotient of the voltage being applied to and measured at the motor terminals and of the blocking current of the armature, and being set in relation to the respective temperature. The current signal determined from the current flowing within the armature is averaged with adjustable, calculated integration times with the aid of an integrator that can be controlled by a microcontroller. The arrangement, can be used for the indirect determination of the rpm rate (N) and/or variations that are critical or of interest in the rpm rate of the motor. The rpm rate is proportional to the voltage (U.sub.ind) induced within the armature, taking into consideration a motor-typical proportionality constant (.kappa.) according to equation N=.kappa. U.sub.ind, with the voltage induced within the armature being determined as the difference between the voltage being applied to the motor terminals and the product of armature current and armature resistance.
