Abstract
The present invention provides control for synchronous machines in order to achieve an approximately constant torque irrespective of the load angle. The induced voltage of the synchronous machine rotating with a zero-current of the stator is first determined. Starting from the voltage plot of the induced voltage over the load angle, a current plot which achieves a constant torque irrespective of the load angle or any other default settings, can then be calculated. In particular, a non-sinusoidal current plot can also be calculated for non-sinusoidal plots of the induced voltage in the synchronous machine, in order to achieve desired settings that are as constant as possible irrespective of the load angle of the synchronous machine.
