    摘要： There is provided a fluid apparatus that includes a fan (15) configured to suction or discharge a gas; a motor (16) configured to drive the fan (15); a battery (26) configured to supply electric power to the motor (16); a current limiting device (32) provided on an electrical conduction path from the battery (26) to the motor (16); a first drive device (40) configured to, when receiving a first drive command from outside, flow a first drive current to the motor (16) through the current limiting device (32), to thereby cause normal rotation of the motor (16); and a second drive device (40) configured to, while a second drive command is being inputted, flow a second drive current, which is larger than the first drive current, from the battery (26) to the motor (16), to thereby cause high speed rotation of the motor (16).

    摘要： The invention relates to an electric motor having a stator (465), to a rotor (470), and to a device for analyzing a signal provided for controlling said motor (11), having a receiving unit (430, 440) for receiving a control signal (PWM_mod), said signal comprising a pulse-width modulated signal (PWM) on which a data signal (DIR, DATA) is modulated, further having an analysis unit (440) for analyzing the modulated control signal (PWM_mod), said analysis unit being designed for determining the data provided for operating the motor (110) starting from the modulated control signal (PWM_mod), and said motor having a signal generator (450) designed for generating at least one control signal for the motor (110) on the basis of the determined data provided for operating the motor (110).

    摘要： A method for determining the rotating position of the drive shaft of a commutated direct current motor by evaluation the current ripple contained in the armature current signal, wherein the metered result of the detected current ripple is corrected when erroneous ripples or double ripples are present. According to the information, determination occurs after detection of a current ripple at a point in time kt t0 at a subsequent point in time or at several subsequent points in time t1...n, the time interval between each subsequent point in time t1...n and the point in time t0 of the previous detection of the current ripple being smaller than the period of the current ripple, whereby the angle of rotation which is set back from the moment t0 of detection of the current ripple is calculated on the basis of actual motor current data and motor characteristic data and, from there, the expected moment in time of the next current ripple detection is calculated. The metered current ripple result is corrected if the expected moment in time resulting from the calculation and the moment of real current ripple detection do not coincide with each other.
