ABSTRACT:
In one aspect a method for operating a synchronous motor is provided. The method includes the following:Determining an electrical angle of rotation on the basis of a speed, with the synchronous motor being controlled according to the electrical angle of rotation,Determining a position of a rotor of the synchronous motor on the basis of the electrical angle or rotation andDetermining the speed on the basis of the position of the rotor.In an other aspect a drive system and a machine are provided. The machine has a plurality of synchronous motors with stator windings used to generate electrical poles. The drive system operates the synchronous motors synchronously.
