St. Louis Demo Motor

Students use the St. Louis Demo Motor to research fundamental principles of electric motors and generators.

• Motor Demonstrates Effects of Pole Separation
• Two-Pole D.C. Armature
• Brush Holder Can Be Rotated for Experiments
• Two Heavy Binding Post Terminals
• Permanent Bar Magnets

This motor consists of a two-pole D.C. armature. The brush holder, with two heavy binding post terminals, can be rotated for experiments.

Permanent bar magnets are fixed in the horizontal plane to demonstrate effects of pole separation. A power supply is required but not included.
