The invention relates to a method for determining the temperature of a rotor of a synchronization machine that is permanently excited with a field-oriented current regulator, said rotor comprising a magnetic rotor field, said synchronizing machine comprising a stator with a stator winding consisting of at least two phase windings. It is provided that an electrical machine equation for a component (Usq) of a stator voltage vector (Us), said component running transversely to the rotor field, is set up in a field-oriented coordinate system, said machine equation containing a magnetic flux (?) of the rotor. It is further provided that the component (Usq) of the stator voltage vector (Us) is replaced by a voltage control variable (UsqCC) of the current regulator or is calculated using the voltage control variable (UsqCC) and that the magnetic flux (?) is determined thereby. In addition, it is provided that the temperature (T) of the rotor is determined from the magnetic flux (?). |
