Lesson Text:


The motors used in robots are typically low voltage direct current motors. To understand how a DC motor
works, it is useful t
o construct a simple motor and describe how it works.

Activities:

Simple DC Motor

1.

Place a D cell battery into a plastic battery holder.

2.

Attach alligator clips to wire support as shown in the diagram.

3.

Obtain a wire loop.

4.

Observe both ends of the wire

loop and record your observations in your notebook.

5.

Set loop ont the wire support and gently nudge the loop into motion.

6.

Observe and record your results.
