    摘要: A motorized head for multiple-head machines for twisting threads or for similar processes includes: a supporting pivot (2) for a thread spindle or reel (3); a rotor (5) that is coaxial to the pivot for unwinding and twisting the thread; a motor connected to the rotor to make it rotate at a controlled speed. The motor consists, for each head, of a single electric motor (8) of the high-efficiency brushless type with cylindrical permanent magnets, directly coupled to the rotor (5). An electronic circuit (11) for speed and power supply control, independent of the circuit of other heads, is associated with the motor. The motor speed and power supply control circuit (11) is a miniaturized frequency converter that is integrated in the motor shell.

    摘要: A unit for controlling the synchronization of a complex machine during power failures or losses, wherein the machine comprises a plurality of motorized devices (A1, A2, A3) for the movement and control of the various components, and wherein each device is connected to the power supply bus by virtue of a speed converter (C1, C2, C3), each device having a known flywheel mass (m1, m2, m3) and having, in the steady state, a speed that is synchronized with that of the other devices. The unit includes: a system (2) for recognizing an actual grid power failure; systems for measuring the speed and the current of the various devices; a computing device (3) for calculating the moments of inertia of the most significant flywheel masses, of their respective speeds and absorbed currents; a circuit (5) for comparing the voltage of the supply bus with the last value of the voltage detected before the grid power failure, suitable to generate a first error signal; a closed-loop regulator circuit (7) for processing the first error signal so as to generate a second signal in output. The second signal can be sent to a multiplier operator (X1, X2, X3) that is associated with each converter to control the gradual and synchronous deceleration of all the devices, converting part of the kinetic energy of the most significant flywheel masses into electric power to supply the system.

    摘要: A method of synchronizing a synchronous reluctance electric machine wherein the machine has no speed and/or residual magnetization voltage sensor and includes power terminals and rotating masses whose mechanical rotation frequency is subjected to speed transients caused by power cut-off conditions. The method includes at least one step of applying a control voltage with predetermined amplitude and duration to the terminals after the transients, and one step of detecting the electric current induced by the control voltage, the current induced by the voltage having a harmonic spectrum variable according to the frequency differential between the frequency of the control voltage and the mechanical rotation frequency of the rotating masses, to restore power and synchronous rotation control of the machine.
