All the parts are open to view, so you can easily show the components of a motor or generator. You can also build on this basic apparatus to perform a variety of demonstrations, including magnetic fields, D.C. motors, series and shunt fields and generators. The motor comes with a two-pole D.C. armature that you can connect to a mechanical device or to another St. Louis Motor for motor and generator demonstrations. Brushes are adjustable for contact with commutators. The two permanent bar magnets are supported by white-plated spring-brass clamps, which can be adjusted to show the effects of pole separation. This versatile teaching tool comes with instructions for performing many experiments. Size: 16cm long, 10cm high. Requires low voltage D.C. power supply.
