This compact, low-voltage model has interchangeable permanent magnets and wire coils. Set up DC motors (permanent magnet, series-wound, or shunt-wound) and generators (AC or DC). Easily find the commutator (DC) and the slip rings (AC) on this working model. Plot voltage signals with probeware then ask students to explain why 1 signal is constant and the other is sinusoidal. Includes detailed instructions.

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.

Helps you teach the following Next Generation Science Standards® Student Performance Expectations:

Rated 1 out of 5 by from Runs too hot. This motor ran great for a short while. I set it up with the permanent magnets, and hooked it up to a 6 volt 12 ah SLA battery. It was running nicely, so I decided to let it continue running for a while. I realize that this motor is probably not rated for “continuous duty” but after about only 45 minutes one of the brushes burned all the way through. I checked the motor over and immediately realized that it was very hot. I used my temp gun to get a couple of temperature readings. The armature coils were at 176 degrees. The brushes themselves temped at a sizzling 203 degrees. I didn’t have an ammeter to check the current draw, but it was definitely pulling a lot of current. I really liked this motor, but was very disappointed that the brushes wore out that quickly. Never got a chance to try it with the coiled magnets.
