The sin/cos encoder consists of magnetic induction sensor function board and rotating magnet, generating a sin / cos analog differential signal per turn, which can meet the application requirements of steering and traction system in transportation and industrial vehicles. The encoder meets the reliability and mechanical strength requirements of the engine (motor) and its associated components, and can be customized with full central control or different sizes according to customer needs.

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).
