The�range�extender�electrical�machine�is�installed�in�the�rear�of�the�I01.
9.3.�Design
The�range�extender�electrical�machine�in�the�I01�is�a�synchronous�machine.�Its�general�structure�and
operating�principle�correspond�to�those�of�a�permanently�excited�synchronous�machine�with�internal
rotor:�The�rotor�is�located�inside�and�is�equipped�with�permanent�magnets.�The�stator�is�ring-shaped
and�located�outside�around�the�rotor.�It�is�shaped�with�iron�cores�through�the�3-phase�coils.�If�a�3-
phase�AC�voltage�is�applied�to�the�stator�coils,�they�generate�a�rotating�magnetic�field,�which�"pulls"
the�magnets�in�the�rotor�(in�engine�operation).
