The rotor consists of a closed conductor loop
connected to the sender arm (rotates with the
sender arm). The conductor loop has the
same geometric shape as the receiver coils.
Construction/design
The angle sensor consists essentially of the
stator and the rotor.
The stator consists of a multilayer circuit
board comprising the exciter coil, three
receiver coils and the control/evaluation
electronics. The three receiver coils have an
angular geometrical star shape and are
arranged out of phase. The exciter coil is
mounted on the back of the circuit board.
