Abstract:
A method for controlling a three-phase AC motor, wherein the three-phase AC motor has a rotatably mounted rotor and a stator including a first group of coils and a second group of coils. Each of the coils generates an oscillating magnetic field upon actuation using an alternating current. The phases of the alternating currents are selected such that the superposition of the magnetic fields of the first group of coils generates a magnetic rotating field that rotates with a direction of rotation and the superposition of the magnetic fields of the second group of coils generates a magnetic rotating field that rotates counter to the direction of rotation. A system composed of a three-phase AC motor and an inverter for carrying out the control method is also described.
