I need a electronic model of a resolver (http://en.wikipedia.org/wiki/Resolver_%28electrical%29) to use in Pspice, because I have to simulate all the electronics to measure the signal provided by this angular sensor.

Can someone tell me where can I find this model? Or in the latest How can I make it?

The spice model of resolver for PSpice is available only in the last version (16.6.) Here you can find articles to try to model the resolver by yourself.

I guess you refer to the resistive component of Z1, Z2, Z3. The data sheet should provide you the Zro, Zso, Zrs as a real part and imaginary part. When you calculate Z1, Z2, Z3 with these values, the real parts are the resistive components.
