Index Explanation
1 Rotor�position�sensor�in�the�range�extender�electrical�machine
2 Connection�for�rotor�position�sensor
3 Connection�for�temperature�sensor
So�that�the�voltages�for�the�coils�in�the�stator�can�be�correctly�calculated�and�generated�by�the�range
extender�electrical�machine�electronics�in�terms�of�amplitude�and�phase�layer,�the�precise�angle
setting�of�the�rotor�must�be�known.�This�is�why�there�is�also�a�rotor�position�sensor�in�the�range
extender�electrical�machine.
The�rotor�position�sensor�is�secured�at�the�stator�of�the�range�extender�electrical�machine�and�works
according�to�the�tilt�sensor�principle.�There�are�three�coils�in�the�rotor�position�sensor.�A�defined
AC�voltage�is�fed�to�one�of�the�coils.�The�other�two�coils�are�each�moved�90°.�The�voltages�induced
in�these�coils�provide�information�about�the�angle�setting�of�the�rotor.�The�rotor�position�sensor�is
mounted�by�the�manufacturer�of�the�range�extender�electrical�machine�at�the�corresponding�alignment
so�that�it�is�already�correctly�adjusted.
