This picture will only mean something to those who know the parts of a DC motor. Next week we will finish the motors and do experiments with them.That armature shaft is a quarter inch in diameter, with four cold rolled steel laminations 2.62" in diameter, epoxied together. The three coils are two hundred turns each of 24 gauge magnet wire, and taped after they are wound.
The commutator segments are copper with the magnet wires soldered to them. The insulator material is heat shrink tubing.
