A method is described for controlling an electric machine during a motor startup operation with the aid of a power electronics device, in particular for use in a motor vehicle. The power electronics device includes a plurality of controllable power switches which are connected for the purpose of supplying an electrical current to the electric machine in polyphase form. The power electronics device is controlled in such a way that the electric machine outputs a startup torque, and the control of the power electronics device for outputting the startup torque takes place in such a way that the switching position of at least two of the power switches is changed, with the result that the power switches are subjected to a more uniform load.
