Weight: 23 grams (0.08oz)
Motor Generator Motor Generator
1840

Similar to a St. Louis Motor, but capable of DC and AC operation. May be operated as a magneto, series motor, shunt motor, series generator and shunt generator. Two permanent magnets and two electromagnets included.
This well-designed apparatus demonstrates both shunt-wound and series-wound connections for motors and generators, and can be used with AC or DC supplies. Includes a 2-pole armature, commutator, brushes, and a coil for use as an electromagnet. Also includes a powerful horseshoe magnet. Easily dismantled to change the configuration. Requires a DC power supply, sold separately. Size: 9 x 9cm x 8cm high.

This model of both an AC and DC motor is quick to put together and easy to assemble and disassemble. This unit is self-contained and even includes the wrench and screw driver needed. Demonstrate both permanent and electromagnet motors. Everything comes packed in it's own protective case which becomes the base for the motor.
AC / DC Generator AC / DC Generator

With this unit both alternating & direct current can be demonstrated. By turning the handle, the current that is produced can be seen as it lights the lamp. The quicker the handle is turned the brighter the light. Each unit is cleaned & lubricated. All units are tested to make sure they meet performance standards.
One-Handed Generator One-Handed Generator
1852

Simple, convenient, and easy! This simple generator can be operated with one hand, and will generate up to ten volts. Moderate cranking speeds will generate approximately 5.5 volts DC The alligator clips on the end of the connection cords provide a convenient hook up to any electrical device. The unit's transparent casing also allows for viewing of the inside workings of the generator during operation. 
(8" x 5-1/2" x 2"; .5lb).
DC Generator - Hand powered DC Generator - Hand powered
1853A, 1853B

This pistol grip style handle generator can be utilized with almost any experiment requiring up to 12 Volts DC current.  Housed in tough clear plastic. This unit is not only functional but costs about half of that of similar models. This generator can also be used as hand generated flashlight due to the mounted lamp on the end or use the binding post to connect an outside electrical circuit.

St. Louis Motor St. Louis Motor
1857

The St. Louis Motor is useful in demonstrating the operations of a DC motor. The motor consists of a 2 pole armature mounted between magnets. The steel supports are mounted on a ridge plastic base. Will operate on 3 to 9 volts DC.
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.
DC Motor Kit DC Motor Kit
1858

This kit  allows students to build their own DC Motor from scratch. All of the needed parts are included along with a detailed instruction manual. The unit is 7.5"x 9"x 5"after assembled and runs on one AA battery.

Demonstrates that the basic structure of a motor and an electric generator is the same. The construction of the apparatus is such that all the parts are readily observable.
DC Motor DC Motor
Y64012

This pre-assembled DC motor was designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. Polarity of the magnets can be reversed to change the direction of rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current. The DC motor can stand vertically or horizontally for best view and operates on a 1.5V battery.
Completely assembled, this open design is similar to diagrams in most textbooks and allows easy learning of motor-related principles. Magnets can be reversed to change direction of the motor’s rotation. To observe change of speed with current, use an external rheostat (not included). Motor can be used vertically or horizontally, for both experiments and demonstrations. Motor is lightweight and can be used with a 1.5V battery or external power supply that you provide. Instructions and storage case included.
Size: 4.5 x 5 x 2".
