(57) Abstract Objective Angle of rotation of the revolving shaft in the brush less resolverWith the gap and phase error of phase of output voltage are improved. Constitution Resolver itself of perform two-phase excitation forma 2 and 1 phase output formaRotary trance 3 opening interval to axis direction, being lockedWith the brush less resolver which is, rotary trance two splitsIt constitutes due to rotary trance 3a and 3b. Two split timesRevolution trance 3a and 3b axis direction both sides of resolver itself 2It lays out symmetrically. And, two split rotary trancesPrimary coil 15a, 15b and secondary winding 13a and 13bYou joint respectively in series.
