对于按照“摇摆使用”的原则工作的内燃机，一个目标，它可以既作为起动马达或作为发电机，电磁单元被创建，以简单的方式在飞轮预定的设计尺寸的适应性和其用于控制​​半导体元件的开支和激励功率如此使用 由于是低在所有可能的。 为此，除其他外， 提出：a）具有排列在切向距离的多个彼此（独立Sektorstatoren（55）定子的每个具有两个（轴向间隔的）连续排列的齿Sektorstator-元件SS1和SS2），并且每个具有一个径向伸出，并通过一个返回轭 （J）在互连杆柄（PS1或PS2），用于励磁绕组（EW1和EW2）; b）中的转子具有两个相对于彼此“齿隙”上交错的离合器飞轮（KS）的外周的齿排; c）对于在电机运行电换向使用MOS晶体管的，逆二极管作为以发电机模式的整流元件和自由运行电路的形成共享。 一个应用是特别适用于汽车的内燃机。

For the principle of "momentum Choose" working internal combustion engine is one that can be used both as a starter motor as a generator, electromagnetic unit to be created, the predetermined design easily to the flywheel dimensions adaptable and their effort for controlling semiconductor components and the excitation power so is low as just possible. For this purpose, inter alia, proposed: a) stator having a plurality arranged in a tangential distance from one another, independent Sektorstatoren (SS) each having two axial distance (a) successively arranged toothed Sektorstator- elements (SS1 and SS2) and each having a radially projecting and by a short-circuit yoke (J) to interconnected pole shanks (PS1 or PS2) for the exciter windings (EW1 or EW 2); b) rotor with two against each other "tooth on gap" staggered rows of teeth on the periphery of the clutch flywheel (KS); c) use of MOS transistors for electrical commutation in motor operation, the inverse diodes are shared as rectifier elements in the generator mode, and the formation of free-running circuits. An application is particularly suitable for automotive internal combustion engines.
