The Magnetic Motor
Objective
Learn the fundamental concepts underlying operation of electric motors.
Assignment
Based on your laboratory experience with magnetic and electromagnetic motors, complete a written lab report with analyses of the following:
- Compare and contrast the tradeoffs for the two versions of the rotary magnet controller. What are the strengths and weaknesses of each version?
- What are the strengths and weaknesses of the battery alternator design? How might you improve it?
