If you are looking for good diagrams you should get a copy of the Electrical Engineering Pocket Handbook. This is a pocket sized book that has a lot of handy information including most of the terminal connection diagrams for motors and transformers. This booklet is published by the Electrical Apparatus Service Association (EASA).
