摘要： The invention relates to a method for starting a synchronous machine, wherein a predefined torque M_V1 is given and a rotational speed of the synchronous machine is adjusted once the synchronous machine has been started, characterized in that, in a first step, a higher torque M_H1 than the predefined torque M_V1 is given and, in the following second step, the torque M_H1 is reduced to the predefined torque M_V1. The invention further relates to a method for starting a synchronous machine, wherein a predefined torque M_V1 is given and a rotational speed of the synchronous machine is adjusted once the synchronous machine has been started, characterized in that, in a first step, a higher torque M_H1 than the predefined torque M_V1 is given. In the following second step, the higher torque M_H1 is reduced to a positive value M_H1a below the predefined torque M_V1 and, in a third step, is increased to the predefined torque M_V1.
