An instantaneous current and instantaneous voltage of a three-phase coil (10) of a brushless DC motor (6) are detected, and the internal condition of a compressor (1) is predicted from these detection values. The prediction about the internal condition of the compressor (1) is made in such a way that motor driving torque which is a parameter of a motor model is identified and poor lubrication, liquid compression or the like is predicted from this identified motor driving torque. This enables it to make, in real time, a failure forecast, failure diagnosis etc. on the compressor (1).

PROBLEM TO BE SOLVED: To modulate continuous capacity from 100% full capacity to 0% of a scroll type machine by a single control mechanism. SOLUTION: Axial or radial relative movement between both scroll members 26, 32 is obtained to release sealing of a fluid pocket between both scroll blades to thereby obtain load release of a machine. Relative movement is accomplished by controlling fluid pressure in one chamber between two fluid pressure chambers 56, 58 by a solenoid valve 68 to move one scroll member 32 in one direction or the other direction or moving the scroll member by the other actuator. Capacity is modulated by making machine operation in a loaded state or load released state periodic. It is therefore recommended to use a sensor 82 for sensing the fluctuating condition of an air-conditioning system or the like, and a valve control module 80. In another embodiment, control mechanism is provided to improve motor efficiency during load release operation.

PURPOSE: To make an output voltage value of a rotation signal sufficiently large, and improve detecting accuracy of the rotation speed by forming an Oldham's link to check rotation of a turning scroll of a magnetic raw material, and arranged an electromagnetic induction system rotation signal detecting means opposite to this. CONSTITUTION: When a rotary shaft 7 is rotated, a turning scroll 14 is driven in turning through turning driving mechanisms 20, 21 and 25, and revolves while rotation is being checked by an Oldham's link 26. As a result, gas flowed in a compression chamber 19 from a suction chamber 28 moves to a central chamber 22 while being compressed, and push-opens a delivery valve 30 of a delivery port 29, and flows outside of a sealed housing 1 after flowing in a delivery cavity 31. In this way, the Oldham's link 26 is formed of a magnetic raw material. An electromagnetic induction type rotation signal detecting means 50 is arranged opposite to the Oldham's link 26. Thereby, and output voltage value generated in the rotation signal detecting means 50 according to reciprocating motion of the Oldham's link 26 can be made sufficiently large. COPYRIGHT: (C)1994,JPO

149 Abnormal operation concentrated predictor for pump JP567184 1984-01-18 JPS60150491A 1985-08-08 MIMURA YOSHIO
PURPOSE:To make a warning signal so as to be emitted at a time when a difference exceeds the specified value, by comparing the operation value required for every pump with each normal value stored in a terminal computer and making the computer store it, while transmitting the value to a main computer with a telephone line. CONSTITUTION:Various numerical values measured automatically by each detector for flow 6, shaft support temperature 7, its vibration 8, pressure 9 and electric power 11 are transmitted to a terminal computer 21 belonging to each pump. A normal value of each of numerical values is inputted into the terminal computer 21, while this value is compared with a numerical value out of each measuring unit, and the different value is stored in memory. And, this comparison result is transmitted to a main computer 22 located in the center with a telephone line 32, and hereat, when there was a difference in the measured value of more than the said specified value or a variation in the measured value within the unit time, a warning signal is emitted out of a warning device 23. With this constitution, automatic operation control over a lot of pumps dispersed in an extensive range and abnormal operation concentrated prediction for pumps are thus attainable.

A motor-driven compressor includes an electric motor, a drive circuit, a modulation method controller, a temperature measuring section, a high-temperature (HT) stop controller, and a high-temperature (HT) stop temperature setting section. The high-temperature (HT) stop controller stops the electric motor when the temperature measured by the temperature measuring section is higher than or equal to a predetermined high-temperature (HT) stop temperature. When the modulation method is the three-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a three-phase high-temperature (HT) stop temperature. When the modulation method is the two-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a two-phase high-temperature (HT) stop temperature, which is higher than the three-phase HT stop temperature.

A beverage syrup pump system is disclosed including a pump housing having an internal pumping chamber, a pump motor, and a pumping mechanism driven by the motor within the pumping chamber. The pumping mechanism receives a syrup fluid at a first pressure and discharges the fluid at a second pressure which is greater than the first pressure.

A programmable micro controller receives the electrical signal from the pressure transducer and is capable of starting and stopping the pump motor. The micro controller will immediately stop the pump motor if the second pressure exceeds a predetermined maximum pressure level. The micro controller will also stop the pump motor if the second pressure falls and remains below a predetermined minimum pressure level for a predetermined first time interval.
