hello everyone, i want to calculate motor windings lost data. What books should I find to read? There are many books on the market, but books worth reading to develop, I am very confused.

 

I doubt books are going to help. Do you have any of the motor manufacturer's name, the motor type, the make and model?

 

See one reference here https://forum.allaboutcircuits.com/threads/how-to-rewind-motor.195434/
By "lost Data" do you mean winding count and wire gauge etc?
