An Inexpensive Hands-on Introduction to DC MotorsDC motors are an important curricular component in most freshman and sophomore introductionto mechanical engineering (ME) courses. In order to facilitate a hands on introduction to DCmotors, an inexpensive DC motor experiment has been developed that gives students anopportunity to build a permanent magnet DC motor from common office items (erasers,paperclips, pencils, rubber bands, etc.) along with a few inexpensive components such as acylindrical tube (such as a film canister) and a pair of magnets. The novelty of the presented DCmotor experiment is that it incorporates all aspects of a typical DC motor including, acommutator and brushes. In this paper, the experiment is presented, along with step-by-stepinstructions on how to build the DC motor. This is followed by preliminary results from smallgroups of sophomore students who were asked to take part in this exercise.
