    摘要: A vacuum pump control device capable of suppressing a power consumption by a vacuum pump by varying the speed of the vacuum pump according to the operating conditions of a vacuum device, wherein a condition set part (4) sets a relation between the operating conditions of the vacuum device (10) and the rotational speed of the vacuum pump (2) for vacuating the vacuum device (10) to a proper value so that the rotational speed of the vacuum pump (2) does not reach a rotational speed more than that required, a control part (6) inputs external signals such as S1 to Sn in correspondence with the operating conditions of the vacuum device (10), reads the rotating speed of the vacuum pump (2) in correspondence with the external signals from the condition set part (4), and outputs the rotational speed, and an inverter (8) controls the rotational speed of the vacuum pump based on the output from the control part (6).

    摘要: A refrigerant cycle apparatus capable of smoothly cooling an inverter module (55) for driving a motor (24) of an electric compressor while preventing enlargement of an installation space as much as possible. In the refrigerant cycle apparatus which is constituted by sequentially connecting the electric compressor (11), a gas cooler (12), an electric expansion valve (4), an evaporator (15) and an accumulator (17) in an annular form through pipes, and driving a motor of the electric compressor by the inverter module (55), the gist of the apparatus is that heat exchange is carried out between the accumulator and the inverter module.

    摘要: Disclosure is made of a precision hydraulic energy delivery system that directly couples the pump to a primary mover (motor) and a related motor control. The system provides flow control of a hydraulically driven machine without the use of downstream devices by employing motion control algorithms in the motor control. Control features are electronically integrated into the hydraulic system by using control algorithms and subroutines specifically developed for the prime mover servo control system coupled to the pump.

    摘要: Es wird ein Verfahren zum Regeln eines Verdichtersatzes, aufweisend wenigstens zwei, von Elektromotoren angetriebenen Verdichtem, wobei einem oder mehreren Verdichtem ein Frequenzumrichter zugeordnet ist und/oder zugeordnet werden kann, beschrieben.
    Erfindungsgemäß werden der und/oder die Frequenzumrichter, bei dem bzw. bei denen der Strom über einen eingestellten und/oder einstellbaren Maximalwert ansteigt oder ansteigen würde, zumindest so lange abgeschaltet oder bei oder unter dem Maximalwert betrieben oder einem anderen Verdichter zugeordnet, bis mittels geeigneter Maßnahmen wieder ein Unterschreiten des Strommaximalwertes erreicht wird.
