About the Series:

This instructional lesson is part of NC-NET's Creating Integrated Instruction series of faculty-developed integrated projects. Interdisciplinary teams of faculty collaborated to develop classroom-ready materials that:

  • Integrate career and technical content and academic concepts—reinforcing both
  • Use real-world scenarios to engage students and make content relevant
  • Foster critical thinking, collaboration, and other skills valued by employers
  • Encourage instructors to use active, authentic assessment techniques

Project Description:

This project is developed around an industry scenario to engage students in the roles of a team of electronics engineer technicians tasked with repairing or replacing a failing motor. Students will apply the physical principles of electromagnetism toward building a working DC electric motor.

Estimated Duration:

Six hours of lab divided into two sessions.

Appropriate Course(s) for Implementation:

  • ELC 131
  • Circuit Analysis I
  • PHY 152
  • College Physics II
