  • the invention relates to a spinning machine with a plurality of synchronously operated electric motors, which are fed via a common operating frequency converter with a predetermined frequency and a startup frequency converter, by means of which one of the electric motors is raised from standstill to synchronous operation.
  • Spinning machines often have a plurality of synchronously running electric motors which are fed by a frequency converter with a predetermined frequency.
  • a frequency converter with a predetermined frequency.
  • one of these motors is to be started up from standstill to the speed of the other synchronous motors, it is connected to a startup frequency inverter, which feeds it with increasing frequency and thereby accelerates it.
  • the motor When the synchronous speed is reached, the motor must be switched from the starting frequency converter to the operating frequency converter.
  • the supply voltage, supply frequency and phase position of the supply frequency in both frequency inverters must match in order to prevent damage to the converter due to surges or voltage peaks.
  • EP 1 589 133 A1 a method is described in which a complex, comparative current measurement with additional components such as current transformers, transformers, comparison circuits with microprocessors are required to determine the time for switching. About the processed current signals, the match of the supply frequency and the phase position is determined and made the switch.
  • DE 10 2004 04 825.0 A1 discloses a method and a device for synchronous switching of a motor between two frequency converters, in which a motor separated from a converter is started up by a startup converter until synchronous operation. As soon as the phase angle of the currents in the starting drive and in the operating converter is the same, the motor is switched over to the operating converter. The synchronization of the phase positions takes place via the evaluation of a sum signal from the two streams of the operating converter and the Hochfahrumrichters.

  • the spindles are equipped with synchronized induction motors that can be synchronized by an inverter power source.

  • a switching device is provided for switching between two different energy sources.
  • EP 1 398 402 A2 an air-spinning machine is shown, in which for the run-up of work organs reluctance motors and a special frequency converter are provided, to which the reluctance motors can be connected. It is assumed that by using reluctance motors can be dispensed with complex speed control in the synchronous operation.
  • DE 34 36 505 A1 discloses a method and a device for controlling a startup converter as a function of the frequency of an operating converter.
  • the frequency supplied to the ramp-up converter is increased in inverse proportion to the frequency of the operating converter.
  • the invention therefore had the task of providing a simpler solution for determining the switching time of a high-speed synchronous motor from the startup frequency converter to the operating frequency converter.
  • the operating parameters of the two converters can be compared easily and in real time and the match can be made when switching.
  • the bus system is advantageously based on a CAN bus.
  • the compared operating parameters the voltage or the frequency and the phase position of the frequency can be used.

  • an operating frequency converter 2 and a startup frequency converter 3 are fed from a network 1.
  • the operating frequency converter continuously emits a specific, as a rule, also changeable supply frequency which can be supplied to at least one synchronous electric motor 4 or via a branched line 5 to a plurality of such synchronous electric motors.
  • a changeover switch 6 is inserted, via which the motors are connected in the operating state to the operating frequency converter, so that they are fed with the predetermined operating frequency of this.
  • the start-up frequency converter 3 is adapted to output a supply frequency which gradually rises from zero and accelerates a synchronous electric motor 4 connected thereto out of a standstill. This startup frequency is also transmitted via a branched line 7 to the switch 6 of the synchronous motors 4.
  • Operating frequency converter 2 and startup frequency converter 3 are connected to each other via a bus line 8, over which the operating parameters such as voltage, frequency and phase angle of the frequency of the two frequency converter are constantly exchanged.
  • a signal generator 9 which transmits a switching signal via a control line 10 the switch 6 outputs.
  • a changeover switch which connects a motor 4 to the startup frequency converter, disconnects it from the startup frequency converter and switches it over to the operating frequency converter. Switched is always only one switch, by which a motor 4 is connected to the startup frequency converter. The switches already on the operating frequency inverter remain unaffected.
  • the switch 6 is automatically switched from its connection to the operating frequency converter 2 to the startup frequency converter 3. However, this initially gives no tension.
  • the startup frequency converter 3 is usually turned off on the startup of only one synchronous electric motor 4, since it is usually designed only for the energy needs of a motor.
  • the machine controller is therefore programmed to always issue command to start up only one motor via input 11 of the startup frequency converter. Only after this is switched to the operating frequency converter 2 and the startup frequency converter rests again, another command to start up another motor can be done. But it is also possible to set up the start-up frequency converter for simultaneous synchronous start-up of two or more engines.
  • the switch 6 can be equipped with a comparison device for supply frequency, supply voltage and phase, which trigger the switchover from the start-up frequency to the operating frequency when they match. Switching always takes place only at a switch that connects a motor with the startup frequency converter.

Abstract

Pour simplifier la conversion d'un moteur électrique (4) synchronisé accéléré du mode d'arrêt au régime de fonctionnement sur un convertisseur de fréquences haute vitesse (3) à un convertisseur de fréquences de fonctionnement (2), il est proposé de relier entre eux les deux convertisseurs par un système de bus (8) auquel les convertisseurs fournissent des paramètres de fonctionnement importants comme la tension, la fréquence et position de phase de la fréquence. En cas de concordance des paramètres de fonctionnement, la conversion du moteur accéléré du convertisseur de fréquences haute vitesse au convertisseur de fréquence de fonctionnement est déclenchée.
