Basic Electricity and Motor Controls
- Course Number: E1008
- Credits: 2 hours
- Instructor: Ellen C. Huang, PE
- Price: $20
Course Outline
This course introduces the fundamentals of electricity and motor controls as they are commonly encountered in small water systems and pumping installations. Participants begin with atomic theory (protons, neutrons, electrons) and how electron movement creates electrical current, then learn the core electrical quantities—voltage (EMF), amperage, and resistance—and their basic symbols and measurement concepts. The course explains open vs. closed circuits, AC vs. DC power, sine waves and frequency (Hertz), and the practical meaning of single-phase vs. three-phase service at pump stations. It then connects electrical theory to real-world motor controls: electromagnets, contactors, magnetic starters, transformers, disconnects/breakers/fuses, thermal overload heaters, common field switches (float, probes, flow, pressure), and routine operational measurements used to maintain reliable pumping systems.
At the end of this course, there will be a multiple-choice, open-book quiz, which is designed to enhance your understanding of the course material.
Learning Objectives
At the conclusion of this course, the student will:
- Be able to explain how atomic structure and electron behavior relate to conductors vs. insulators and the flow of electrical current.
- Be able to define voltage (EMF), current, resistance, and frequency.
- Be able to distinguish between single-phase and three-phase power (sources, conductors, and phase timing).
- Be able to identify the purpose and basic function of common pumping electrical components from transformers to magnetic starters.
