電圧パルスを取出すことができる。 Inductive transmitters are known for measuring rotational angles, in particular in ignition distributors of internal combustion engines, which detect a certain angular position between stator and rotor. Furthermore, the stator and rotor are provided with teeth such that the teeth of the rotor move past the teeth of the stator at defined angular positions during rotation of the rotor. In this case, the magnetic flux changes in a magnetic circuit, which is usually formed by permanent magnets connected to the stator and rotor, which are used as conductor parts, and which surrounds a coil in which the teeth of the stator are rotated. A voltage pulse can be taken out each time the child tooth moves past.
