I pulled a transformer out of an radio's power supply circuit that I had. I was going to use it for protyping. How would one go about testing what it converts from and coverts to?

 

If it is mains input then apply power to the primary and measure the secondary(s) voltage(s), you could do a resistance check to find out if the secondaries are connected or have centre taps.
The physical size of the core will give a rough estimation of VA size.

A photo doesn't help that much.
Where were the leads connected? Did any of them go to the mains power?

The black and white are mains leads sry

 

What does that have to do with a motor armature and where/what is the Tfmr?

I'm talking about the actual wound copper. Inside the motor on the motor shaft

 

What has that to do with a transformer from a radio power supply?
Unless this is some kind of rotary convertor???

I'm confused with this mention of a motor.

Has this thread been broken off from another?

 

Damnit wrong thread. I am running three atm. But thanks for the help
