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.
