The Hall element is used directly and indirectly in the detection process, that is, the direct detection of the magnetic field characteristics, and this switching device also uses the magnetic field as a carrier to carry out more pressure positions and so on. detection and control. For example, the Hall element, when detecting how many turns the motor rotates, usually uses a magnet to generate a voltage difference, so as long as there are a few voltage differences, you can know how many turns it turns, so the effect of this use is still very obvious. For example, in the green ignition system, this kind of sensor is used as an ignition pulse generator, which can not be affected by the environment, and can be accurately ignited to better control the primary current. The principle is that with the change of the magnetic field, a voltage measurement is generated in the semiconductor layer to control the ignition. This advantage of no maintenance and no preservation has a great impact on the performance improvement of the engine.
