  • the imbalance and / or the loading of the laundry drum is then deduced.
  • the current flowing through the winding of the stator and / or the intermediate circuit voltage is used to determine the load and / or the imbalance of the laundry drum.
  • the fact that the current flowing through the winding during generator operation and the intermediate circuit voltage represent a measure of the moment of inertia of the laundry drum and thus of its charge is used. This relationship is especially true immediately after the transition to generator operation - it is thus advantageous if the determination of the load and / or imbalance is initiated with this transition.
  • the measurement of the current and / or the intermediate circuit voltage can also begin with this transition or immediately thereafter. However, the measurement of the current and / or the DC link voltage can also be done in addition to engine operation.
  • the unbalance and the load can be determined individually for each
  • a permanent-magnet synchronous motor is preferably used as an electric motor.
  • Such synchronous motors are known to be characterized by high efficiencies over z. B. Asynchronous motors off.

  • it is possible to use such a permanent-magnet synchronous motor whose stator has a three-phase design and thus has a total of three windings - so-called phase phases. Currents in all windings of the stator are preferably measured and evaluated with regard to the loading and / or the imbalance of the laundry drum. With a three-phase stator, measured values are available for a total of three currents for determining the load and / or the unbalance. The results of this determination can then be compared.

In other words, in this embodiment, a relationship between the load and / or the imbalance to the measured values for the current and / or for the intermediate circuit voltage is modeled. It may, for example, be such that a plurality of value ranges are predetermined for the current and / or for the intermediate circuit voltage, which is assigned to a respective load of the laundry drum.

It may for example be such that the moment of inertia of an unloaded laundry drum is stored in a memory of the control unit and the moment of inertia of the loaded laundry drum is determined in the generator mode. The moment of inertia caused by the loading of the laundry drum can then be calculated as a measure of the load by a simple subtraction.
  • a profile of the power supplied by the electric motor in generator operation for the duration of one revolution of the laundry drum is evaluated, and depending on this course, the imbalance of the laundry drum is determined. It takes advantage of the fact that the imbalance of the laundry drum can be detected by means of a fluctuation in the course of the power for the duration of one drum revolution.
