Description: The components of the model are mounted in a rectangular steel frame about 38cm high and 48cm wide. The main components of the model are two field coils, two armature coils, and a commutator.
All coils are of the samesize and are wound with insulated copper wire. To help the student distinquish between the north and south magnetic poles, one field coil and one armature coil are painted blue, the other two coils are painted orange.
The armature, well-balanced on the frame, is mounted between low-friction bearings at the base and thus revolves smoothly. The model can be operated on less than 6VDC. A 6V latern battery or three or four 1.5V batteries connected in series are sufficient for any operation, although any 6VDC power supply will work.
