PURPOSE: To directly obtain resolver signals from a variable magneto-resistance synchro through four windings connected in serial adding and serial subtracting directions. CONSTITUTION: Four parallel conductors A1 -A4 are wound around each pole in a phase A in the clockwise direction around poles 1, 3, 4, and 6 and in the counterclockwise direction around poles 3 and 5. The conductors in phases B and C are also wound in the same manner. When the teeth of a rotor are aligned with those of a stator, the inductance becomes higher and a high voltage is generated across the windings and, when the rotor rotates and the teeth of the rotor get out of the alignment, the voltage drops. When the first conductors A1 , B1 , and C1 are connected in series with an AC power source 36 and an exciting signal is supplied, resolver signals of R2 cosθand R1 sinθcan be obtained respectively from the serial connection of conductors B2 , B3 , C2 , and C3 and the serial connection of conductors A2 , A3 , B4 , and C4 .
