The invention relates to a method and an apparatus for the field-oriented control of a polyphase machine. In this case, an actual torque of the polyphase machine is determined, the determined actual torque is compared with a desired torque and, in the event of the occurrence of discrepancies in the torque, the desired values for the flux-forming current and the torque-forming current are changed in order to bring the actual torque into line with the desired torque. The actual torque is calculated by means of the power balance of the polyphase machine. |
