Figure 3. Classical Resolver vs. Variable Reluctance Resolver
A classical resolver is a rotating transformer that typically has a
primary winding on the rotor and two secondary windings on
the stator. A variable reluctance resolver, on the other hand, has the
primary and secondary windings on the stator and no windings
on the rotor, as shown in Figure 3; however, the saliency in this
rotor design provides the sinusoidal variation in the secondary
coupling with the angular position. For both designs, the resolver
output voltages (S3 S1, S2 S4) are as follows:

where:
θ is the shaft angle.
Sin(ωt) is the rotor excitation frequency.
E0 is the rotor excitation amplitude.
The stator windings are displaced mechanically by 90° (see
Figure 3). The primary winding is excited with an ac reference.
The amplitude of subsequent coupling onto the 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 the shaft angle. Resolver format signals refer to the
signals derived from the output of a resolver, as shown in
Equation 1. Figure 4 illustrates the output format.
