A simple kit for students to gain insight into field poles, armatures and switches, one mounting base, two coils of insulated wire , field pole, mounting bracket, two armature halves, one piece of insulating tubing, motor shaft, two commutator insulators, two bronze wire brushes, two shaft supports, four paper fasteners, a AA battery holder and 6 each of screws and nuts.
Requires one AA battery, not supplied, with assembly instructions.
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.
Comprising 1 welding coil of 5 turns on former with insulated handle and short-circuiting pins,1 annular melting trough with insulated handle to show heating by induction,1 jumping ring which is thrown clear when primary current is started and a floating ring which remains freely suspended when primary current is flowing.
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.
With driving wheel, to generate current, mounted on polished wood base with driving wheel in vertical position, a lamp holder and a lamp.
Output DC Current
Output both DC and AC current
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.
