Electrical Motor Controls
Course Description:
This course, developed by Bridgerland Technical College, teaches students about electrical symbols and schematics. In the course, students use wiring diagrams and schematics to wire basic and advanced control circuits. Students also design, simulate, and wire circuits that include control relays, timing relays, and motor starters. Upon completing the course, students should be able to:
- identify the working characteristics of basic electrical motor control devices such as: push buttons, selector switches, over current devices, control relays, overload devices, contactors, and overload blocks,
- identify ANSI electrical symbols for basic electrical motor control devices,
- use ANSI symbols to design, install, and troubleshoot basic electrical motor control systems,
- read and draw wiring diagrams and schematics,
- wire and operate circuits from schematics,
- wire basic control circuits such as power, reversing, interlocking, plugging, inching, timing, and automatic starting circuits from schematics,
- use line diagrams, schematic drawings, and test equipment to isolate problems in basic electrical control systems,
- follow a step-by-step troubleshooting process to solve problems within an integrated system.
