Electric motors, transformers, and control systems are used in all modern industries. Knowledge of the characteristics of these will help the electrical engineering technologist keep the wheels of industry turning. This book will give the student a practical introduction to electrical machinery, transformers, and motor control. The experiments have all been used at the Pennsylvania State University, Mckeesport Campus. There, the full series of experiments were done in two semesters. Each experiment requires about two hours of laboratory time. The book is designed to accompany a textbook. As...

This book teaches and demonstrates the basics of Siemens S7-200 Programmable Logic Controllers (PLCs). The S7-200 uses Step 7-Micro/WIN programming software. It does this with the Siemens CPU 222 S7-200 PLC. Information is provided to help the reader get and operate a CPU 222, associated hardware, and software. Examples with ladder program diagrams and circuit diagrams are provided to demonstrate S7-200 and Step 7-Micro/WIN capabilities. A person completing the examples will be able to write useful programs for the S7-200.
