METHOD AND DEVICE FOR CONTROLLING A SYNCHRONOUS MACHINE
In a method for controlling a synchronous machine having a stator, a rotor, and magnets situated on the rotor, first a nominal value is set for the magnetic flux prevailing in the synchronous machine, and a marker is set in a control unit that indicates that no calibration has yet been carried out....

| description | In a method for controlling a synchronous machine having a stator, a rotor, and magnets situated on the rotor, first a nominal value is set for the magnetic flux prevailing in the synchronous machine, and a marker is set in a control unit that indicates that no calibration has yet been carried out. It is then checked repeatedly whether the synchronous machine has been out of operation for at least a specified time duration. If this is the case, a temperature balance between the stator and the rotor is assumed, so that the temperature to be measured at the stator is equal to the rotor temperature, and thus can be used as a basis for a calibration of the magnetic flux. A marker that indicates the carrying out of a flux calibration is set in the control unit. Subsequently, normal operation can be continued. |
