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.
