Consider the typical manufacturing shop. A wide range of machines and tools are used that rely on motion. When industry needs motion to turn or drive devices, it most often uses electric motors. Electric motors are one of the prime movers for industry. If motors are not installed, used, and maintained correctly, essential work does not get done.
These classes explain the fundamental concepts of designing, providing, and maintaining electrical control for motors. The class content first addresses the main elements of motors and the principles that make motors work, with several classes devoted to reading the symbols and line diagrams used to represent electrical circuits. Advanced-level classes focus on simple to complex control devices--the physical switches, contactors, and relays that open and close electrical circuits, allowing motors to perform useful work.
