Magnetic conduction type absolute angle detection system

The invention discloses a magnetic conduction type absolute angle detection system, for solving the problems of quite large size, complex coiling process and high manufacture cost of a conventional toroidal transformer. The system comprises a magnetic conduction type absolute angle detection apparatus and an angle detection signal processing apparatus. The magnetic conduction type absolute angle detection apparatus comprises a first stator, a second stator, a first coil assembly, a second coil assembly, a third coil assembly, a fourth coil assembly, a magnetic isolation pad, a first wiring board, a second wiring board, a first rotor and a second rotor. Under the condition that it is ensured that absolute angle information is known, the magnetic conduction type absolute angle detection system refines an angle value and improves the detection precision. Compared to a conventional magneto-resistive rotary transformer, the magnetic conduction type absolute angle detection system is high in measuring precision, simple and practical in structure and quite good in development prospect.
