Abstract: Method for controlling a permanent magnet synchronous motor, wherein an equivalent circuit describing the characteristics of the permanent magnet synchronous motor is formed, and via calculations based on. the equivalent circuit, a vectorial representation of the control quantities is produced, in which the horizontal axis of the co-ordinate system used represents the magnetisation, the vertical axis represents the torque and the vectors used are stator voltage (Us), supply voltage (e) and current (I), which is at a distance of 90° from the horizontal axis. In the vectorial representation, a correction vector (dU) is formed via inference based on the equivalent circuit and the correction vector is summed with the electromotive force, giving the stator voltage (Us) as a result.
