Lesson Plan: Direct Current Motors Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the use of a commutator in producing uniform circular motion from the output of a direct current source.


Students will be able to

  • interpret diagrams of dc motor coils at different rotation angles relative to a commutator to determine the resultant torque direction on the motor.


Students should already be familiar with

  • electromagnetic induction.


Students will not cover

  • calculations of rotational motion.
