<P>PROBLEM TO BE SOLVED: To automatically obtain reduction in power consumption and in vibration. <P>SOLUTION: A motor drive system is provided with a motor (1) that drives a load whose load torque periodically fluctuates and a motor control device (3a). Computing a torque current command value (iδ<SP>*</SP>) from the difference between an estimated motor speed (ω<SB>e</SB>), and a motor speed command value (ω<SP>*</SP>), the motor control device extracts a fluctuating component deriving from a load torque fluctuation by the difference, by using a resonance filter (30) and superimposes the extracted value on the torque current command value (iδ<SP>*</SP>) as a torque current offset value (iδ<SB>C</SB>). Then, the motor control device is provided with a phase control part (32) that adjusts the phase of the torque current offset value, by controlling a resonance filter, based on the superimposed torque current command value. <P>COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To reduce the deviation between a rated pressure and an air tank pressure under the different loadings, and to prevent a large rise of the air tank pressure even though the loading is reduced. SOLUTION: An air pressure control throttle valve 9 is provided in a suction pipe 7, and a motor has an air pressure control governor 6. Both the governor 6 and the throttle valve 9 are connected to a compressed air tank 14 through a compressed air pipe 26 and a control device 18, and the control device 18 includes an electric air pressure valve 19 in the compressed air pipe 26 connected to an electronic controller 20, while a pressure gauge 21 is connected to the compressed air tank 14, and a pressure gauge 22 is provided in the compressed air pipe 26 between a valve 19, and the governor 6 and the throttle valve 9. A controller 20 is connected to both pressure gauges, and a means to control the electric air pressure valve 19, as the functions of the measured air tank pressure, the measured regulation pressure, and the rated pressure regulated electronically, is provided.

A method of controlling the production efficiency of a well includes determining one or more parameters of a pump model for a pump of the well, determining an inflow rate of liquid into the well, and adjusting a pumping speed of the pump based on the one or more parameters of the pump model to maintain a outflow rate of liquid from the well at a desired fraction of the inflow rate.
15 Liquid Ring Vacuum Pump with Cavitation Regulation US14364083 2012-12-12 US20140377084A1 2014-12-25 Heiner Kösters; Matthias Tamm; Daniel Schütze
A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.
16 SYSTEM AND METHOD OF OPERATION OF MULTIPLE SCREW COMPRESSORS WITH CONTINUOUSLY VARIABLE SPEED TO PROVIDE NOISE CANCELLATION US11626482 2007-01-24 US20080175717A1 2008-07-24 Harold Robert Schnetzka; E. Curtis Eichelberger; Paul Nemit
A system for cancelling or attenuating noise in at least two positive displacement compressors proximately located from each other for use with a heating or cooling system. A lead compressor and a lag compressor have a controllable rotational speed and phase of operation. A controller selectably controls the rotational speed and the phase of operation of each of the compressors. The controller controls the rotational speed of the compressors at substantially the same speed for each compressor, with a phase-lock loop and a comparator circuit for each compressor. The controller controls the phase of operation of the compressors through an oscillator so that the lead and lag compressor pressure pulses are spaced between successive outlet pressure pulses to effectively double the combined pulsation frequency for noise attenuation.
17 Rapidly pumping out an enclosure while limiting energy consumption US11396574 2006-04-04 US20060222506A1 2006-10-05 Jean-Luc Rival
A vacuum pumping device of the invention comprises a motor (1) driving a multi-stage dry mechanical pump (2) in which the stages (5, 6, 7, 8) are connected successively in parallel and then in series in a plurality of successive configurations, each of which is selected to optimize the pumping speed in the current pressure range. This makes it possible to lower pressure inside an enclosure (100) quickly while reducing the volume of the pump and the energy consumed by the pump by about 40% compared with a traditional pump having a speed that is sufficient to obtain the same rapidity of pumping.
18 System and method for noise attenuation of screw compressors US10728157 2003-12-04 US20050123407A1 2005-06-09 Harold Schnetzka; E. Curtis Eichelberger; Paul Nemit
A system is provided for attenuating noise in at least two positive displacement compressors proximately located from each other for use with at least one heating or cooling system. A lead compressor and a lag compressor have a selectably controllable rotational speed and a selectably controllable phase of operation. A controller selectably controls the rotational speed and the phase of operation of each of the compressors. The controller controls the rotational speed of the compressors at a predetermined rotational speed that is substantially the same for each of the compressors. The controller controls the phase of operation of the compressors by shifting the phase of operation of the lag compressor so that an outlet pressure pulse operatively produced by the lag compressor is substantially evenly spaced between successive outlet pressure pulses operatively produced by the reference compressor.
19 Auxiliary solenoid controlled variable displacement power steering pump US09826268 2001-04-03 US20020139604A1 2002-10-03 Steven Thomas Nissen; Brian Stanley Modrzejewski; Shawn Patrick Cap'ser
An auxiliary solenoid controlled variable displacement power steering pump, hydraulic systems incorporating same, and method for improving the efficiency of variable displacement power steering pumps. In one embodiment, a rotor is arranged within a pump body, and a cam fitted on an outer periphery of the rotor and movably arranged within the pump body to form a variable volume pump chamber. The cam is biased towards a position within the pump body to create maximum displacement. A mechanism is provided for forcing the cam into a position of fixed minimum or reduced displacement under certain conditions, such as low engine speed and power steering demand. In a preferred embodiment, the mechanism comprises a solenoid driven connecting rod that is operatively connected to the cam. Activation of the solenoid forces the cam to a position of fixed minimum or reduced displacement.
