Depending on the configuration of a spinning electromotive device the stator may act as the `` field magnet '' , interacting with the armature to create motion , or it may act as the `` armature '' , receiving its influence from moving field coils on the rotor .
The stator might act as the field magnet ( working with the armature to create the spinning movement ) or as the armature ( receives influence from the moving field coils of the rotor ) .
