ABSTRACT:
For an internal combustion engine, such as a motor vehicle engine, operating on the principle of "flywheel utilization" an electromagnetic unit can be used both as a starter motor and as a generator. In addition, this unit is easily adaptable to the given flywheel dimensions and it involves as low a cost as possible for the controlling semiconductor components and for the exciter power. The invention proposes, among other things: (a) a stator with several independent sector stators arranged at tangential distance from each other, with pairs of toothed sector stator elements arranged at an axial distance a one behind the other and each having a radially projecting pole shank connected together by a flux return yoke; (b) a rotor with two rows of teeth mutually offset "tooth on gap" on the circumference of the clutch flywheel; and (c) use of MOS transistors for the electrical commutating of motor operation, the inverse diodes of which are utilized as rectifier elements in generator operation.
