Figure 24. Classical Resolver vs. Variable Reluctance Resolver
A resolver is a rotating transformer, typically with a primary
winding on the rotor and two secondary windings on the stator.
In the case of a variable reluctance resolver, there are no wind-
ings on the rotor, as shown in Figure 24. The primary winding
is on the stator as well as the secondary windings, but the saliency
in the rotor design provides the sinusoidal variation in the
secondary coupling with the angular position. Either way, the
resolver output voltages (S3 S1, S2 S4) have the same
equations, as shown in Equation 1.

where:
θ is the shaft angle.
Sinωt is the rotor excitation frequency.
E0 is the rotor excitation amplitude.
The stator windings are displaced mechanically by 90° (see
Figure 24). The primary winding is excited with an ac reference.
The amplitude of subsequent coupling onto the stator secondary
windings is a function of the position of the rotor (shaft) relative to
the stator. The resolver, therefore, produces two output voltages
(S3 S1, S2 S4) modulated by the sine and cosine of shaft
angle. Resolver format signals refer to the signals derived from
the output of a resolver, as shown in Equation 1. Figure 25
illustrates the output format.
