Abstract:
A method for operating an electrical machine, wherein an inverter of the electrical machine is actuated by a pulse width modulation. In one case, it is provided that a pulse duty factor for the pulse width modulation is determined from a voltage value (d) that is dependent on the desired rotational speed as well as a time-dependent angle value (α). Embodiments of the invention further relate to an electrical machine.

Claim (Index 5):
The method according to  claim 1 , wherein in that, in the summation of the angle value (\u03b1), as an additional summand, a difference between a first angle (\u03b3) and a second angle (\u03b3\u2032) is used, wherein the first angle (\u03b3) is determined from the desired rotational speed (\u03c9) and the field attenuation value (\u03c6) and the second angle (\u03b3\u2032) corresponds to the previous value of the first angle (\u03b3) or is determined from measured phase currents (I U , I V ) through the inverter.
