Basics of a Resolver transformer....

[Physicslearner500039]

Can somebody please explain me the basics of resolver. How it works? How it calculates angle and velocity? Atleast any proper links. Please help.

Generally how much time does it take for the resolver to lock to the cos and sine signals and calculate the velocity?

A resolver is essentially laminated steel and several coils of copper wire arranged in a particular way. It doesn't do calculations, nor does it lock anything - these things are done by whatever electronics are connected to it.

Take a look at; “Synchro and Resolver Conversion, Geoffrey Boyes, Analog Devices, 1980”

You will find a direct link in the Analog Devices list of downloads. See page 31.

There is plenty to read in that list.

Resolver is an analog device, interpreting the signals all depends on the interface. Here is a Patent on the scheme, worth the read.

Resolver systems are used in industrial robotics, can be quite accurate and fast - but the limit? Each system will be designed to meet the needs of the application.
