Motors and Motor Control Circuits Course Syllabus

Overview: This course provides a comprehensive, industry-focused introduction to motors and motor control circuits, designed for aspiring electrical engineers and automation professionals. Over approximately 24–30 weeks of part-time study, learners will progress from fundamental motor principles to advanced control techniques, combining theoretical knowledge with hands-on circuit design and simulation exercises. The curriculum covers DC, AC, and stepper motors, relay-based control systems, variable frequency drives (VFDs), protection mechanisms, and real-world troubleshooting. The course concludes with a capstone project involving the design and simulation of a functional motor control circuit. Estimated total time commitment: 120–150 hours.
