Synchronous machines have long been known in many different forms. In operation as a generator and also in operation as a motor, in the situation of a short-circuit, for example a short-circuit at connecting terminals or also within the stator winding, such synchronous machines produce very high short-circuit torques. In that respect, those very high short-circuit torque peaks can reach values of up to six to eight times the rated torque of the synchronous machine. Therefore, consideration must also be given to the very rare short-circuit situation and the concomitant occurrence of a very high short-circuit torque, in regard to the mechanical construction of the synchronous machine. |
