    摘要: A motor control device performing vector control for a motor that drives a load whose load torque varies periodically. The motor control device has: a motor speed deriving portion estimating or detecting a motor speed; a speed controller producing a specified torque current value such that the motor speed is made to follow a specified motor speed value fed from outside; a resonance filter producing a corrected torque current value by receiving a control value that varies with variations in the load torque and emphasizing a periodic variation component of the control value; a torque current corrector producing a specified superimposed torque current value by superimposing the corrected torque current value on the specified torque current value; and an adjusting portion adjusting, based on the specified superimposed torque current value, the phase of the corrected torque value by controlling the resonance filter. The vector control is performed according to the specified superimposed torque current value.

    摘要: 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.

    摘要: 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.

    摘要: To provide an operation control device for a vacuum pump and a method for stopping the operation of the vacuum pump that make it possible to effectively remove products, resulting from solidification and liquefaction of gas in a casing and possibly hindering the rotation of a pump rotor, so that the vacuum pump may be started normally. An operation control device 10 for a vacuum pump having a pump rotor 1 disposed in a casing 2 for free rotation includes a pump rotor control section 15 for controlling the rotation of the pump rotor 1. The pump rotor control section 15 has a function to, after a pump stop action has been taken, rotate the pump rotor 1 in forward and/or reverse directions according to a predetermined timing pattern and then stop the pump rotor 1.

    摘要: 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.
