The classic St. Louis Motor gives students a great introduction to electric motors!
Now, modern high strength magnets, precision engineering, and industrial brush technology have brought this traditional apparatus up to date. The open design allows students to identify the parts of the motor and investigate their function. Adjustable brush holder and magnet supports let you change the direction of rotation and magnetic field strength. Requires connector wires and a single battery (we recommend a D size battery) or power supply. 4.5" x 3.75" x 3.25". Includes operation and experiment manual.
