用于切断机动车的电流激励式同步电机的方法
摘要：
本发明涉及一种用于切断机动车的电流激励式同步电机的方法，电流激励式同步电机具有转子(R)和定子(S)且通过功率电子装置供电，转子(R)通过功率电子装置的激励电路(20)供电，定子(S)通过功率电子装置的桥电路(30)供电。所述方法包括以下步骤：将用于转子(R)和定子(S)的电流输入中断；将激励电路(20)转换到第一空载位置中，使得包含在激励电路(20)以及转子(R)中的能量经由第一反馈装置(D2、D3)被供给到第一能量存储器(HVS1)中；将桥电路(30)转换到第二空载位置中，使得包含在桥电路(30)以及定子(S)中的能量经由第二反馈装置(D5-D10)被供给到第二能量存储器(HVS2)中。
摘要（英）：

The invention relates to a method for switching off a current-excited synchronous machine of a motor vehicle comprising a rotor (R) and a stator (S) and supplied by means of power electronics, whereinthe rotor (R) is supplied via an excitation circuit (20) of the power electronics and the stator (S) is supplied via a bridge circuit (30) of the power electronics. The method comprises the followingsteps: interrupting the current supply to the rotor (R) and the stator (S); switching the excitation circuit (20) into a first freewheeling position, so that the energy contained in the excitation circuit (20) and in the rotor (R) is fed into a first energy storage device (HVS1) via a first feedback arrangement (D2, D3); and switching the bridge circuit (30) into a second freewheeling position, so that the energy contained in the bridge circuit (30) and in the stator (S) is fed into a second energy storage device (HVS2) via a second feedback arrangement (D5-D10).
