Since the process on the Stator flow of the stepper motor is oriented, is a highly dynamic Control of the drive reached.
  • the principle of the stepper motor is based on the fact that a permanent magnet executed rotor itself within a stator with several windings turns. To move the rotor, they are offset from each other arranged windings supplied with current after a time sequence. Magnetic fields are generated in connection with the magnetic field of the rotor allow the movement of the rotor.
  • the Stator is formed from a variety of windings, called pole pairs determine the step size of the stepper motor.
  • the torque of the The stepper motor is driven by the magnetic flux in the stator (Stator flux) and the magnetic flux in the rotor (rotor flux) are determined.
  • the rotor Since the rotor is designed as a permanent magnet, the rotor flux will increase do not change, so that the torque of the stepper motor in essentially by the stator flux amplitude and the angle to Rotor flux is affected.
  • the method according to the invention now uses this dependence on the movement of the rotor and thus the Control the traversing thread guide.
  • To control the stator flow a stator voltage generated by a flow control device given.
  • the movement of the rotor is changing magnetic excitations with given magnetic Stator flow controlled in the stator windings.
  • Torque generated by the stepper motor is controlled.

  • a corresponding torque correction value is generated, which is used to control the stepper motor in the stator voltage becomes. This allows one to guide each in the traversing device of the traversing thread guide in every position of the traversing thread guide generate sufficient torque and acceleration.
  • the stator voltage generated by the torque control the phase position, i.e. regulate the angular velocity of the rotor.
  • the torque acting on the rotor is essentially dependent on the position of the rotor, the rotor flux and the stator flux. Since the Rotor has a constant rotor flux, can be according to one particularly advantageous development of the invention, the actual torque solely from the electrical parameters stator current and stator flux to calculate. There are two options here, the current actual stator flow of the stepper motor.
  • the first possibility is that the rotor position is encoderless is determined.
  • the stator voltage and the stator current continuously measured and linked in a calculation circuit in such a way that results in a stator flux dependent on the rotor position.
  • the actual torque can now be determined, so that the determined actual torque is compared with a target torque can be.
  • the target torque results from the law of motion of the traversing thread guide and depends on the respective Wrapping laws known.
  • the torque can be removed from the position and the speed of the traversing thread guide for each position of the Determine the rotor beforehand and is given to the torque controller.
  • the Angular position of the rotor detected by a sensor and in the control of the stepper motor included. Bring these location signals in Phase equilibrium with the rotor, so you have a standardized Rotor flux signal.
  • These standardized rotor flux signals can be advantageously in transfer appropriate stator flow signals. So that is the stator flow known.
  • the actual stator flow is continuously determined and a flow controller for actual-target comparison given up.
  • a flow controller for actual-target comparison can be advantageous Correct interference immediately.
  • the stepper motor can have a target stand flow profile be specified that exactly the movement of the traversing thread guide reproduces.

  • the flow control device 1 is connected to a sensor 3, which senses the position of the rotor or the rotor shaft 5.
  • the Flow control device also has an input for the transmission of Target values for the change.
  • a winding spindle 15 is arranged below the belt drive, on the a sleeve 14 is attached.
  • a coil 13 is placed on the sleeve 14 wrapped.
  • a thread from the traversing thread guide 8 along the Coil surface moved back and forth.
  • the flow control device 1 the stepper motor 4 for each traversing thread guide position Field sizes for influencing the rotor can be specified.
  • the operation of the stepper motor can be described as follows using the schematic illustration shown in FIG. 2.
  • the stepping motor 4 has at least two windings 16 and 17 arranged offset by 90 ° to one another.
  • the windings 16 and 17 are alternately controlled by a converter 2 according to a predetermined time sequence.
  • a magnetic field with a magnetic flux ⁇ S builds up in the windings.
  • a load current (stator current) i S flows in windings.
  • a rotor (not shown here) mounted in the middle of the windings will move with its permanent magnetic field.
  • a sensor 3 is attached to the stepper motor to detect the position of the rotor.
  • the sensor 3 is designed so that the number of steps of the sensor can be divided in whole numbers by the number of pole pairs of the step motor.
  • His signal can thus be used for position control of the rotor as well as for stator flux determination.
  • Particularly simple relationships result when a gearwheel is used whose number of teeth is identical to the number of pole pairs of the motor.
  • a sine signal and a cosine signal are obtained by means of two field plates, which have an offset of 90 ° in relation to the tooth pitch. If you bring these signals into phase equilibrium with the rotor, you get my normalized rotor flux signal.
  • the instantaneous stator current i S and the sensor signal ⁇ are then - as shown in FIG. 3 - given to a converter 18 of the flow control.
  • the flow control device is shown schematically in FIG. 3. Vector sizes are indicated by an arrow.
  • the converter 18 determines an actual value of the stator flux ⁇ S from the stator current and the sensor signal ⁇ .
  • the actual value of the stator flux is then fed to a flux regulator 20 and at the same time to a torque regulator 19.
  • a comparison is made directly at the controller input between a predetermined setpoint value of the stator flow with the instantaneous actual value of the stator flow.
  • the flux controller 20 will generate a voltage signal which is applied to a pulse width modulator 21 which is connected to the converter 2.
  • a comparison is made in the torque controller 19 between a predetermined target value of the torque and the actual value of the torque of the stepping motor.
  • the actual torque is determined from the given values of the stator current i S and the stator flux ⁇ S. If there is a deviation, the torque controller 19 likewise generates a voltage signal which is fed to the pulse width modulator 21.

  • the equivalent circuit diagram shown in FIG. 4 and the pointer diagram shown in FIG. 5 are also used to describe the stepping motor.
  • the machine sizes are understood as space pointers in a fixed coordinate system, the ⁇ axis of the coordinate system coinciding with the winding axis of the machine and the ⁇ axis being orthogonal to the ⁇ axis.
  • p is the number of pole pairs of the stepper motor
  • ⁇ is the angle between the stator and rotor flux space pointer.
  • the rotor flux cannot be influenced in its amplitude because of the permanent excitation. Its position only depends on the position of the rotor.
  • the tip of the stator flow space pointer should be guided on a circular path. This can be achieved in that a voltage space vector uM is connected to the winding, the direction of which is orthogonal to the stator flow direction. Since the stator flux ⁇ S is essentially an integral of the stator voltage, such a voltage space pointer sets the stator flow space pointer ⁇ S in rotation. However, this voltage space pointer alone can only influence the angular velocity ⁇ , but not the amplitude of the stator flux. Therefore a further voltage space vector u ⁇ is required which points in the direction of the stator flow space vector ⁇ S.
  • the stator voltage u S is thus the sum of the two components u M and u ⁇ .
  • stator flux in the stepper motor can thus be determined or controlled in its amplitude and in its phase position by the stator voltage u S.
  • the output signal of the stator voltage can be used directly as an input signal of a pulse width modulator after appropriate standardization. It should be noted that the voltage space pointer can only be influenced in the periods in which the converter is still clocking.
  • stator flow can now be a flow controller or a Torque regulator are abandoned.
  • FIG. 6 shows a block diagram of a combined control of a stator flux and the torque.
