A resolver is a rotary transformer that providesinformation on the rotor position angle induces the voltages E S1-S3 and E S2-S4 into the two outputwindings of the stator.The magnitude of the output voltages vary with the sineand the cosine of the rotor position angle θ .The stator bobbin winding is energized with an ACvoltage E R1-R2 . This AC voltage is transferred to the rotorwinding with transformation ratio θ , because thetwo secondary windings are shifted by 90. Tr . The AC voltage then Input:E > R1-R2 Output:E > S1-S3 E > S2-S4 Input Signal:E > R1-R2 = E > sin( Џ t) Output Signal:E >...

The accuracy ε is defined as the difference between theelectrical angle accuracy absoluteђ or the accuracy spreadђ iscaused by the internal error of the resolver and the mounting error resulting in 1st and 2nd order harmonicsof the sinusoidal signal.At low speeds the θ > el , indicated by the output voltages of thesecondary windings, and the mechanical angle or rotorposition angle θ > mech .accuracy ( accuracy rippleђ effects the speedstability of a drive. This ripple is caused by 3rd andhigher order harmonics. To ensure smooth drive performance even at low speeds LTN resolvers have...
