This paper aims to develop a computer program for to support of designed small capacity single phase transformers; same as recovery design of three phase and single phase motor windings types. The approach is research and synthesis document on winding design of electric machine in domestic and foreign. Then, conducted to design an algorithm flowchart and write a computer program. Research parameters are input parameters of transformers and steel core parameters of the electric machine are used. Research results show that software is high reliability and high accuracy, proven products attend to over 80% same as the data supplied from the manufacturer.
