摘要： PROBLEM TO BE SOLVED: To provide a flywheel uninterruptible power supply unit, capable of saving the capacities of a wire-wound induction machine, an inverter, and a converter. SOLUTION: This flywheel uninterruptible power supply unit, formed so that a flywheel is connected to the wire-wound induction machine to form a flywheel generator, the primary winding of the wire-wound induction machine is connected to a load side, and the secondary winding thereof supplies power from a commercial power source via the converter and the inverter, receives power supply from the commercial power source when the commercial power source is stabilized to store the power in the flywheel, and cuts off a breaker when the voltage of the commercial power source is lowered to supply the power to the load. The wire-wound induction machine is rotated faster than synchronous speed, exciting current depending on the rotational speed of the flywheel and the frequency of a system is supplied to the secondary winding for variable speed control, thus it is possible to save the capacities of the wire- wound induction machine, the inverter, and the converter than that of a conventional flywheel uninterruptible power supply unit.

摘要： PURPOSE:To prevent a motor shaft and a rotary blade inside a frame from the intrusion of magnetic flux and eliminate the generation of overcurrent and exothermic reaction by disposing outside the frame a ring formed of a superconductive material to surround the frame. CONSTITUTION:A turbo molecular pump carries out a gas molecule pumping action with rotary blades 2 connected to a motor shaft 1 and fixed blades 3 disposed alternatively between the rotary blades 2. Then, a vacuum tank 5 is disposed outside a frame 4 and a cooling container 6 is disposed in the vacuum tank 5 while a ring 7 formed of a superconductive material is disposed in the cooling container 6. The cooling container 6 is filled with a cooling material such as liquefied nitrogen introduced from an inlet 8 to cool the ring 7 until the superconductive condition is attained. Thus, the motor shaft 1 and the rotary blades 2 inside the ring 7 under the superconductive condition are prevented from the intrusion of magnetic flux. Thus, rotary sections even under the ferromagnetic circumference can be prevented from the generation of overcurrent and exothermic reaction.

摘要： PURPOSE:To detect phenomena of abnormality, hindrance and failure in a rotary machine in their early stages and to minimize the damage of the machine by a method wherein an area allowed by a normal state of the rotary machine is set in a multi- dimensional space formed by the total amount of state which is expressed by multi- dimensional vectors obtained by unifying conditions of operation and the amounts of phenomena. CONSTITUTION:An operational condition detecting means 31 digitizes conditions of operation such as the number of revolutions and an output and a phenomenon amount detecting means 32 the amounts of phenomena such as shaft vibration resulting from the operation of a rotary machine by A/D conversion means 33 and 34 respectively and output them to an arithmetic means 35. The arithmetic means 35 sets an area allowed by a normal state of the rotary machine in a multi-dimensional space formed by the total amount of state which is expressed as multi-dimensional vectors obtained by integrating the conditions of operation and the amounts of phenomena, and determines the state of operation as sound when the total amount of state obtained by integrating the conditions of operation and the amounts of phenomena inputted is found inside the set normal state, while it determines the state of operation as extraordinary when the total amount of state is found outside the normal state.

摘要： PURPOSE:To discriminate the electromagnetic vibration of the electric motor and to detect the abnormality of the roller bearing by cutting off an electromagnetic vibration component consisting of plural ray spectra. CONSTITUTION:The detection signal of a sensor part 1 installed on a bearing bracket is inputted to a fast Fourier transformer 19 through an LPF 8 and an A/D converter 9 to obtain a Fourier spectrum. Then an electromagnetic vibration spectrum removing part 20 substitutes the higher harmonic vibration spectrum in the Fourier spectrum by the groove higher harmonic magnetic flux of the electric motor and the frequency spectrum component determined according to the operation conditions of an inverter for electric motor driving with zeros. Then a time waveform is obtained by fast reverse Fourier transformation 21 and then the influence of electromagnetic vibration is removed from the obtained signal and vibration which is generated nearly by the bearing is detected. For the purpose, this signal is led to an effective value detection part 2 and a peak value detection part 3 and compared with a predetermined value and when the value is exceeded, a decision 6 on the abnormality is made.
