Pulse generator arrangement for determining the positional angle and rate of rotation of an engine especially a vehicle starter motor using the same pulse generator wheel for both measurements

摘要

The measuring arrangement includes a pulse generator wheel (3) and several sensors (7-9) which cooperate with the wheel. The sensors for measuring the angle and also the sensors for measuring the rate of rotation cooperate with the same pulse generator wheel. The wheel preferably has a series of teeth with which the sensors cooperate. Preferably at least one of the sensors works according to the Differential Hall principle. Most preferably all of the sensors are identical.
