Angular motor location (figure 31 )
The motor's angular registration is achieved by means of a gearwheel attached to the crankshaft and a sensor (Hall effect or inductive). The number of teeth on this wheel varies according to the application (in particular, depending on the maximum engine speed and the desired angular accuracy). Classically, automotive applications have 60 teeth (spaced 6˚ apart), including a singularity...
