DYNAMO MODEL AC (LSE)
A simple demonstration of a Dynamo Model mounted on a wooden base of size 200x170mm. Hand driven by a gear. Simplified open frame construction which can be readily understood without detriments to its essential similarity to real machine. A 2 pole armature wound by enameled copper wire to rotate in U shape magnet in pivot. While in rotation process through the gear wheel by hand, the bulb provided glows.

DEMONSTRATION DYNAMO (LSE)
This model uses the same basic assembly as the electric motor in Cat. No. 8060 but is mounted on a base plate 225x100mm which also carries a hand drive pulley 120mm in diameter coupled to the smaller dynamo pulley by a rubber belt. Electric output is via a pair of 4mm socket & a light emitting diode is provided as simple output indicator. The model may also be used as motor on a 4 to 8 volts DC supply.

DYNAMO MODEL AC/DC (LSE)
A simple dynamo model to differentiate AC from DC. Mounted on a wooden base 300x150x160mm approx. Two bulbs are provided for AC & DC current(s). The model is hand driven & when operated, the AC bulb shows flickering light to indicate AC current while the other bulb glows fully indicating DC current.

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. Size: 4.5 x 5 x 2".
