Abstract

In a method for starting a synchronous machine, a default torque is predefined, and a rotational speed of the synchronous machine is adjusted after starting. A torque which is higher than the default torque is predefined, and the higher torque is reduced in the subsequent second step to a positive value which is less than the default torque, and is increased to the default torque in a third step.
