Third Session

The Creator Club

Semester 1, Session 3

Title: Making a motor that that can do real work.

Goals of this session: To help the boys make a working motor that has enough power to actually do something.

In this session the boys will use all of the tools more extensively to build a real working three pole armature motor. The club leader will show them a two pole armature and demonstrate it in his working motor project. The boys will observe its shortcomings and then build a motor that is much more practical.

Each boy will cut parts from wood, sheet metal and other materials and assemble his own motor that we will later use in projects that do work.

If we have time, we will make wooden pulleys to show the relationship between speed and torque, and power.
