Abstract
The control generator of an ignition distributor for a transistor-coil ignition comprises an annular coil (55), a rotor (54) and a stator, which is a riveted unit comprising a stator plate (18), a permanent magnet (17) and a pole disc (56). The rotor and the pole disc are molded elements of sintered iron or of a mixture of sintered iron powder and carbonyl iron powder having a binder of thermosetting resin. The rotor and the pole disc have cooperating pole teeth (59,51), which are directed parallel to the axis (60) and whose cross section is triangular, with the triangular tips oriented toward one another. These 'pointed teeth' produce a more steeply inclined signal course, as a result of which a decreased inherent shifting of the inductive transducer, and thereby more reliable starting of the engine, are attained.
