摘要： PROBLEM TO BE SOLVED: To provide the subject ring fine spinning frame designed to obviate such problems that use of an induction machine as a single spindle-driving motor is accompanied by altering the revolutions of the relevant single spindle as well as the weight of yarns thereon to result in altering yarn twist level and a spindle where an abnormality such as yarn breakage occurred cannot be stopped alone by remote control operation. SOLUTION: This single spindle-driven ring fine spinning frame mounted with a single spindle-driving motor on each of the spindles works as follows: the single spindle-driving motor which is a synchronous motor is subjected to pulse width modulation control based on the difference between an externally inputted speed instruction and synchronous motor speed corresponding to the speed instruction; a control signal used for the drive control of the synchronous motor represents PWM duty, which is monitored, and when it is suddenly changed, the relevant spindle-driving motor is halted; in this way, by monitoring the PWM duty of the synchronous motor on a software, when the PWM duty is suddenly changed, the relevant spindle-driving motor is halted.

摘要： PROBLEM TO BE SOLVED: To determine the yarn break and the abnormality of a power-supplying part to a motor in a spinning machine having each spindle independently driven by the motor installed for each of the spindles. SOLUTION: An electric current value at the input side of an inverter installed for each spindle is measured by a currant sensor to control the drive of a spindle motor. A judging circuit judges the presence or absence of yarn break and abnormality of a power-supplying part by comparing the measured current value with threshold Iα. The measured value of the current by the current sensor when the spindle motor is normally rotated in the state in which an empty bobbin is attached to the spindle is used as the threshold Iα. The judging circuit judges that the state is the yarn break state when the measured current shows a constant value not less than the threshold Iα and the value continues for a prescribed time, and that the state is the abnormality of the power-supplying part when the value is a prescribed constant value less than the threshold Iα and continues for a prescribed time. The judging circuit distinguishes the abnormality of the power-supplying part into the partial abnormality of a phase wiring in the inverter, and the abnormality without the phase wiring in the inverter.

摘要： PROBLEM TO BE SOLVED: To prevent a foreign matter from entering into the space between a rotor and a stator even if a spindle taken out from a bolster and in the state of the foreign matter adsorbing on the periphery surface of the rotor of the spindle is set at the original position. SOLUTION: This motor 1 for driving a single spindle is integrated with the spindle 3 supported by a bolster 2. A disc-like supporting part 9 covering upper end part of the bolster 2 is installed at the intermediate part of the spindle 3, and a magnet rotor 10 is fixed at the out side of the supporting part 9 so as to be integrally rotated. A stator 11 is fixed at the position facing to the rotor 10 in a motor housing 4, and a spindle-inserting hole 13 is formed at the upper side member 4b of the motor housing 4. A cylindrical rubber bush 15 is attached to the inside of a cylinder part 14 constituting the spindle-inserting hole 13. The rubber bush 15 is formed so as to have the same inner diameter as the outer diameter of the rotor 10, and the foreign matter adsorbed on the surface of the rotor 10 is removed when the rotor passes through the rubber bush 15.

摘要： PROBLEM TO BE SOLVED: To cope with both usual discharge capacity control for stably maintain a room temperature and repid reduction of the discharge capacity as an emergency evacuation step at an emergency. SOLUTION: A load torque detector 60 detects load torque generated in a compressor as a reaction against a compression motion. A control device 70 calculates a load torque target value based on a results compared between a set temperature in a temperature set station 73 and a temperature detected by a temperature sensor 74. A discharge capacity of the compressor is controlled by feedback-controlling the passage of electric current through a solenoid coil 54 of a control value 40 so as to bring a measured load torque near the target value under a normal condition. On the other hand, the feedback control is interrupted to control the passage of the electric current through the solenoid coil 54 to minimize the discharge capacity at an emergency when a temporary reduction of the load torque of the compressor is requested for reducing a burden of a drive source.

摘要： PROBLEM TO BE SOLVED: To provide an SR linear motor which can make thrust ripples smaller by hardly lowering its average thrust by changing the shapes of poles on the primary side, on which field coils are wound and which usually becomes a stator. SOLUTION: An SR linear motor 11, which is driven with a three-phase alternating current, has two or more sets of three-pole units having primary-side poles 13a-13f wound with field coils 14. The poles 13b, 13d, and 13f, having rectangular cross sections and the poles 13a, 13c, and 13e having tapered front ends, are arranged alternately. Accordingly, the poles 13a-13f are formed, in such a way that the distances L1 and L2 between the center lines O1 and O3 of the facing sides of the front end faces of the poles 13a, 13b, 13d, and 13e which are positioned on both sides of the central pole 13c of the continuous five poles 13a-13e and the center lines O2 and O4 of the poles 13b and 13e positioned on the downstream side in the moving direction of a moving piece become different from each other.
