摘要： A closed loop control system for a electromagnetic clutch or brake (312) has a motor to provide force, a transducer (304) to read the force and produce an error signal, and an amplifier (311) to compare the error signal to a reference signal. The amplifier (311) will produce an output signal proportional to the input signal(s) and regulate the clutch or brake (312) accordingly. Additional transducers (305, 306) can be added so that torque, velocity and position can be considered. The signals from these transducers (304, 305, 306) can also be used to further condition and control output to the brake (312) or clutch.

摘要： Verfahren zur Regelung des tatsächlichen Werts (Istwert) einer physikalischen Grösse auf einen vorgegebenen Wert (Sollwert), mit folgenden Schritten: a) die Differenz zwischen Sollwert und Istwert, im folgenden Regelabweichung genannt, und deren Vorzeichen, im folgenden Regelvorzeichen genannt, werden in zeitlichen Abständen repetitiv bestimmt; b) die Regelabweichung wird während oder nach jeder Messung in mindestens ein elektrisches Signal umgesetzt, dessen Zeitdauer, im folgenden Regelabweichungs-Zeitdauer genannt, mindestens im Bereich des Sollwerts dem Absolutwert der Regelabweichung proportional ist und dessen Grösse eine Funktion des Regelvorzeichens ist; c) mit diesem mindestens einen elektrischen Signal wird während der Regelabweichungs-Zeitdauer die Ladung einer analogen elektrischen Speicheranordnung beeinflusst; d) abhängig von der Grösse der Ladung der Speicheranordnung wird die physikalische Grösse direkt oder indirekt beeinflusst, um sie im Bereich des Sollwerts zu halten. Dieses teils auf analogen, teils auf digitalen Elementen beruhende Regelverfahren ermöglicht bei einem Motor, der z.B. zur Kommutierung oder zu Steuerungszwecken einen Mikroprozessor verwendet, einen sehr einfachen Aufbau eines Drehzahlreglers.

摘要： The invention relates to a method for driving an electric screwing device during which a control device supplies electric current in the form of pulse signals to an electric motor. In addition, the motor generates a torque which turns a screwing tool with a rotational speed for driving a screw. In order to relieve a device operator from the burdensome support of the reaction moment as greatly as possible, the invention provides that the interpulse period between two pulse signals is determined in such a way that the rotational speed of the motor during the interpulse period is significantly reduced.

摘要： Die Erfindung bezieht sich auf ein Verfahren zur Impulsbreitenbegrenzung zur Unterdrückung von Regelschwingungen, bei der Drehzahlregelung eines Elektrokleinstmotors (7), der nach dem Regelprinzip der RI-Kompensation in seiner Drehzahl regelbar ist. Beim Nachregeln der Leistung des Elektrokleinstmotors (7) durch den RI-Regelbaustein (10) wird die minimal mögliche Impulsbreite abhängig von der Leistungsnachregelung am Elektrokleinstmotor (7) variiert.

摘要： The invention relates to a method for controlling at least two electrical consumers in a single circuit arrangement with pulse width modulated signals. According to the invention, a supply current which flows during the pulse pause of said pulse width modulated signals and is dependent on an inductor of the electrical connection lines is taken up by a buffer capacitor. The pulse width modulated signals are generated with time delay.

摘要： The invention relates to an electronically commutated engine comprising a stator carrying several winding phases and a rotor. The individual winding phases can be controlled through final power stages over time-delayed periods divided into control times and dead times. To reduce power loss during the final power stages and, thus, to raise effectiveness, especially in the case of heavy currents, the invention provides for the control periods to be divided into an initial period and an end period. When the engine currents are low, clocking by pulse-width modulation occurs only during the initial or end periods, whereas, when currents are heavy, the current is fully switched through during the initial periods and additionally for a more or less long part of the end periods or during the end periods and additionally for a more or less long part of the initial periods.

摘要： A controller for DC motor is provided with an FET (206) which is connected between one end of a motor (201) and the positive electrode of a battery EB, a diode (203) through which the electric current having flown through the motor (201) is passed when the switch (220) of the battery EB is turned off, a means for measuring the current flowing through the motor (201) which comprises a shunt resistor (203a), a differential amplifier (203b), and a low-pass filter (203c), and a controller (250) which PWM-controls the turn-on/off of the FET (206) so that the measured value of the current flowing through the motor (201) is coincident with a target value. The controller (250) sets a very small value as the target value when the switch (220) of the battery EB is turned off and supplies the very small current to the motor (201). Therefore, the FET which drives the motor of a bicycle with auxiliary motor is protected at a low cost without adding any extra component.
