Set up DC motors (permanent magnet, series-wound, or shunt-wound) and generators (AC or DC) to teach current, Faraday's law, Lenz's law, motors, or generators. Both the magnets and coil mounts slide in and out of slots on the base. The distance between the magnet and the rotor armature can be adjusted by rotating the magnet. Depending on the configuration with or without the meters, 2 to 8 connecting cables may be needed. The rotor axle is mounted on factory-adjusted cone bearings that should not need further attention. Note: It is normal to see sparking at the commutator when the motor is running. Accumulating black deposits may be carefully removed with fine emery paper.
Includes detailed instructions. Power source (6- to 12-V DC; 2 to 5 A, item #757100), connecting cables (items #756523 and #756515), and meters (items #369570 and #369580) are needed for advanced experiments but not included. An adjustable power source (item #757213) is also recommended.
