Demonstration Electric Motor

A simple model of a DC electric motor, having a 2-pole armature wound with enameled copper wire on an insulated plastic bobbin. The magnetic field is provided by a removable permanent magnet. The model is completely open with all components easily identifiable and clearly observable. A disc-type commutator is incorporated and external connection to the phosphorus bronze bushes is by means of a pair of 4mm colour coded sockets. The motor operates on 6-8 volts DC.
