Course Learning Outcomes
Upon successful completion of this course, students will be able to:
- Differentiate between major types of electric vehicle motors and describe their basic operating principles.
- Identify key components of electric vehicle motors—such as stators, rotors, and control electronics—and explain their functions.
- Diagnose common faults in electric vehicle motors using industry-standard diagnostic tools and software
- Perform motor repair procedures on electric vehicle motors, including disassembly, fault inspection, and replacement of faulty defective components.
- Complete a full motor overhaul, including precision reassembly, lubrication, and Performance testing.
- Interpret and apply manufacturer technical manuals and specifications for motor maintenance and repair tasks.
Prior Learning Assessment & Recognition (PLAR)
Students may request formal recognition of prior learning attained through informal education, work, or other life experience. Assessment will include the following:
Technical reports, diagnostic records, or motor service documentation created and/or used by the applicant in their workplace, which are judged equivalent to the curriculum documents required in the Electric Vehicle Motor Rebuilding course assignments.
A successful interview with the Electronics Programs’ Department Head or one of the department’s full-time faculty, focusing on diagnostic strategies, simulation-based troubleshooting, and safety procedures specific to EV traction motors and their control systems.
An essay in which the applicant reflects on and analyzes their prior experience in relation to the themes, issues, and concepts of the course, such as motor failure modes, waveform and signal interpretation, simulation-based testing, and principles of motor rebuilding.

Instructional Strategies
Instructional time is primarily focused on classroom-based learning, including lectures, demonstrations, audio-visual presentations, and guided exercises to build a solid theoretical understanding of automotive control module diagnostics and repair. Simulations are incorporated to reinforce key concepts and provide opportunities for applying diagnostic techniques in virtual scenarios. Select hands-on activities may be used to enhance understanding of course content and support the application of theoretical concepts.
