Variable Reluctance Resolver - 59 Series
Variable reluctance resolver is an electromagnetic sensor consisting of a stator and a rotor. When the AC magnetic field generated by the excitation winding is periodically stable, the rotor rotation causes the air gap magnetic field between the stator and the rotor to change, which is feedback to the secondary winding inductance to change, thereby inducing the electromotive force to change, forming a voltage signal, which is converted by A/D to Digital signal (i.e. angle signal).
