Apparatus is designed primarily for demonstration of the basic principles of transformers.
It consists of a laminated U-core with laminated I-core, both with 32 x 25 mm cross section to form a closed core of size 102 x 127 mm.
Heavy aluminium alloy stand with removable clamping rods, 2 pole pieces, each 65 x 30 x 25 mm with one end cone shaped, to accept support rod and shading ring.
Poles also have a hole drilled through lengthwise to take a light beam. 300 turns 600 turns 1200 turns 3600 turns 12000 turns
The dynamo model is mounted on a base with a driving wheel.
Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.
For use on double 'C' core, wound with 1,100 turns of 22 swg copper wire with a resistance of about 6 ohms and inductance of about 15 henries, size 100 x 60 x 55 mm approx.
Students can explore how a simple electric motor works by doing a series of investigations.
This St. Louis motor can be adjusted so students can study the effect of voltage and position of the brushes on the commutator.
The motor consists of a two pole DC armature. The brush holder, with two heavy binding post terminals, can be rotated for experiments.
The permanent bar magnets, supported by clamps, can be adjusted to the desired location.
This apparatus requires 4 D cell batteries with holder (not included) or a power supply and two connecting leads (not included).
The large size of this battery operated apparatus allows students to better understand the operation of this basic circuit.
Works on 9 V Battery.
Includes Instructions.
On wooden stand.
