Electromechanical Components and Mechanisms

Course Description

This combined lecture and laboratory course (ETS 2527C) introduces students to the principles, identification, selection, and application of electromechanical components and mechanisms used in industrial and automated systems. Students explore how electrical signals interact with mechanical processes through hands-on investigation of motors, actuators, sensors, relays, solenoids, and drive mechanisms. Emphasis is placed on the integration of electrical and mechanical systems, component specification, circuit assembly, and basic troubleshooting of electromechanical devices. The “C” suffix designates a combined lecture and laboratory course meeting in the same place at the same time.

This course is offered within the Engineering Technologies — Specialty Engineering Technology taxonomy of the Florida Statewide Course Numbering System (SCNS) and is a sophomore-level (2000) course typically offered in Engineering Technology A.S. degree and Advanced Manufacturing programs at Florida colleges.
