Hi,

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?

Regards,

Carlos

Hi Carlos,

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.

If you like, share your results with us

Hello,

For sure I will try to make the model, and I will share it 🙂

Hello Rever75,

If I have the Z1, Z2 and Z3 of the t-network, is it possible to calculate the RL of Z1, Z2 and Z3?

Hi,

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.

Thanks Rever,

The datasheet provides me with the Rp, RS and the Zro, Zso, Zrs.

So, I would like to see how to calculate the Z1, Z2 and Z3. To see if my calculi are right.

Regards,
Carlos

Z3 = √[( Zso ( Zro – Zrs))]

Z2 = Zso – Z3

Z1 = Zro – Z3
