I am working at a small firm engaged in repairing and rewinding of electrical machines like Motors and Alternators. I am in this industry for the past 13 years. Here I am sharing some of my experience with AC Motors and Alternators. I hope it will be helpful to those in similar field and will help me when they share their experiences here.
