    摘要： An arrangement for energy economy in a drive which includes an induction motor and a clutch-brake unit, particularly for sewing machines is provided. The windings of the induction motor are dimensioned so that the motor speed remains virtually constant in a stable speed range under normal service conditions, and in which the clutch-brake unit serves to control the drive output speed, so that the motor operates in an alternation of load phases and no-load phases. Switches are included in the current paths of the windings, which reduce the current through the windings to a prescribable degree. A modulation circuit to control the acceleration of the motor speed and its persistence in the stable speed range during load variations is associated with the switches. The modulation circuit contains a delay element, which is triggered when the mains voltage is applied, and an impulse prolongation element having a time constant dimensioned so that the motor remains in the stable speed range under all service conditions.

    摘要： A control circuit configured to control an electromechanical brake is provided. The control circuit includes: a switching regulator configured to control a magnitude of voltage applied to a brake coil of the electromechanical brake; wherein said switching regulator includes at least one semiconductor switch, one diode, one capacitor and one inductor; the control circuit is configured such that, in operation, at least one signal from a process sub-system specifies the magnitude of the voltage for the brake coil; and at least one brake applying control signal from a safety sub-system can cause the brake coil voltage to be reduced to a level low enough to apply the brake by opening a switch and each brake applying control signal from the safety sub-system has a corresponding diagnostic feedback signal to the safety sub-system that indicates the state of the corresponding switch. A method and a system are disclosed.

    摘要： A brushless motor drive device includes the following: an inverter circuit configured to energize and drive the winding of a brushless motor; a current detection circuit configured to detect the current value of the winding; a control unit configured to control the rotation of the motor; and an RC filter including a resistor and a capacitor. The control unit includes the following: a drive control unit configured to generate a signal to drive the inverter; a clock generation circuit configured to generate a clock pulse to be used as a reference for an operation period; a pulse output circuit configured to generate a pulse signal with a changing frequency based on the clock pulse and to apply the pulse signal to the RC filter; an AD converter circuit connected to the capacitor of the RC filter and the current detection circuit; and an AD-conversion-error calculation unit configured to calculate the conversion error of the AD converter circuit. The AD-conversion-error calculation unit calculates the conversion error based on the difference between the output value of the AD converter circuit produced in response to an input of the voltage of the capacitor and an AD-converted value calculated from the charging time of the capacitor.

    摘要： A short circuit detection circuit and a short circuit detection method for a multi-phase rectifier are provided, which are used for detecting conditions of a spectrum of a FWR signal outputted from the multi-phase rectifier in the frequency domain. Next, determining whether the detected signal indicating the amplitude of the frequency of the AC signal is greater than or equal to the reference signal, so as to determine whether the multi-phase rectifier has a short circuit condition. Therefore, the short circuit detection circuit and the short circuit detection method do not have any requirements for configuring a short circuit detection element on each current path of the multi-phase rectifier, so that the power loss and the cost can be reduced effectively.

    摘要： A centrifuge includes a regenerative braking safety system including an electrical system reversibly coupled to a power source. A motor is coupled to the electrical system. The motor is capable of driving a rotor using power delivered through the electrical system, and is further capable of supplying the electrical system with recovered energy. The recovered energy is electrical energy converted from kinetic energy of the rotor during regenerative braking of the motor. The safety system includes a power cut-off configured to disable the effect of regenerative braking of the motor when the electrical system is decoupled from the power source.
