Definitions

  • the invention is in the field of electrical engineering and relates in particular to synchronous machines.
  • Such synchronous machines can be operated as rotating electrical machines both as a motor and as a generator.
  • Corresponding synchronous drives are widely used in industry as machine drives, but also as actuators.
  • Such a synchronous machine basically has a stator with stator windings, so-called phase windings, which generate a magnetic rotating field in the region of the rotor. A corresponding activation of the phase windings causes the magnetic field to rotate.
  • the control of the phase windings of the stator is usually carried out by electronically controlled converter circuits, which are designed with power semiconductors.
  • the rotor lags the stator rotary field more or less by an angle a, which is referred to as Polradwinkel or load angle. If the load is too large, the load angle increases beyond a tilt angle, at which the drive stops.
  • a control of the machine then adjusts, for example, voltages or current intensities at the phase windings in such a way that a desired behavior, in particular a time-dependent desired position, of the synchronous machine is achieved.
  • a disadvantage of such methods is that the determination of the absolute position of the rotor requires corresponding sensors and hardware expenditure as well as a certain amount of computing power in the control device.
  • the indirect determination of the absolute position of the rotor via electrical variables also requires computing power.
  • the determination of the absolute rotor position is also time-consuming, so that a reaction of the control can not often take place at the desired speed when changing the load.
  • a corresponding design of the commutation in the control of the phase windings is necessary, so that further boundary conditions for the control arise, which complicate the scheme.
  • Typical problems that arise with such control methods are acoustic suggestions and slow reaction of the control under load changes and possibly also vibration behavior of the controlled variable, for example, the rotor speed, which, for example, vibrations of the load angle can be caused up to reaching the tilt angle.
  • the present invention is based on the background of the prior art, the object to provide a stable method for operating a synchronous machine, which allows the simplest and most effective control even with load changes, and manages with the least expensive control device.

  • phase windings usually at least two or three phase windings are provided for generating the rotary field, which are supplied via the drive means with power.
  • the control device generates time-dependent voltages in the form of pulse-width-modulated signals from electronic control signals for the individual phase windings.
  • appropriate voltages are applied to the phase windings.
  • the voltages are usually supplied to the pulse width modulation by an electrical intermediate circuit, which is part of a semiconductor bridge circuit with controllable semiconductor switches, for example transistors, field-effect transistors or IGBTs.
  • the desired voltage and the current intensity at the phase windings are then set via the pulse width modulation.
  • the measuring device can measure, for example, the voltage drop across the phase windings and, for example, also detect the induced voltage generated by the rotor in the stator winding, which can be set in relation to the drive voltages of the phase windings.
  • a load angle can already be determined without directly determining a rotor position. It can also be a variable representative of the load angle between the stator field and the rotor at a specific time, which is determined by the stator field periodicity, which is reached when the optimum load factor is reached. Angle at this time expected induced voltage compared with the actually induced voltage at this time and the difference value of the further control are used as a basis, until this difference value has been adjusted down to zero. When the difference disappears, the optimized load angle is reached.
  • the measured values of the measured variable (s) can also be converted into a rotor position additionally and independently of the control mechanism and thus also provide information about the load angle. This calculation process can be carried out at low speed and with little computation because it does not provide any size needed for the control.
