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. The object of the invention is to simplify the synchronous machine in regard to its structure and to avoid the above-mentioned disadvantages. A synchronous machine having a rotor and a stator, wherein the stator has at least two independent alternating (three-phase) current windings which are electrically and/or spatially isolated from each other.</ SDOAB> |
