For anyone interested in learning more about electric motors, the information included in my post is largely from your own US Navy's training manuals.

There's a company called "Integrated Publishing", and they have a web site he

Repair and Maintenance Manuals - Integrated Publishing

Integated Publishing is a bit of a scam. What they do is sell people the information contained in your US military's training courses.

Now, since all of the training manuals the US military uses to train their recruits was compiled at tax payer's expense, it's publicly owned material, and Integrated Publishing cannot sell the stuff to you because you already own it.

So, what Integrated Publishing charges you for is the service of photocopying those training manuals and sending you paper copies, or putting the information on a CD-ROM and sending you that disk.

But, the information is great. The stuff on electric motors comes from a section called "NEETS" which stands for Navy Electrical Engineering Training Series.

The NEETS series of training manuals starts on this page:

and the section that discusses AC electric motors (which is Chapter 4) starts on this page:
