Slip Ring Capsule SC 020-R Operating Principle: Slip Ring Brush Isolator |xxxxxxxxxxxxxxxxxxxx| Isolator Operating Principle Resolver A resolver is a contact less rotary transformer that provides information on the rotor position angle 8. The stator bobbin winding is energized with an AC voltage ER1R2. This AC voltage is transferred to the rotor winding with transformation ratio Tr. The AC voltage then induces the voltages ES1^3 and ES2^4 into the two output The magnitude of the output voltages vary with the sine and the cosine of the rotor position angle 8, because the two secondary...

Slip Ring Capsule SC 020-R Accuracy Resolver The accuracy ε is defined as the difference between the electrical angle θel, indicated by the output voltages of the secondary windings, and the mechanical angle or rotor position angle θmech. The ‘accuracy absolute’ or the ‘accuracy spread’ is caused by the internal error of the resolver and the mounting error resulting in 1st and 2nd order harmonics of the sinusoidal signal. accuracy (ε) = electrical angle (θel ) – mechanical angle (θmech) The ‘accuracy ripple’ has decisive influence on the speed stability of a drive. This ripple is caused by...
