Product Description

Demountable Transformer

This apparatus has been designed primarily for demonstration of the basic principles of the AC transformers and electromagnetic induction. The cores and various coils included also serve as the basis of many experiments in electromagnetism, using either direct or alternating current. Complete with one each of U shaped and I-shaped iron core with base having in built clamping system. The complete unit consists of

Clamp base with a laminated ‘U’ Core and laminated armature

2 soft-iron pole pieces

1 300-turn 4A coil

2 600-turn 2A coil

1 1200-turn 1A coil

1 3600-turn 0.3A coil, center tapped

1 12000-turn 0.05A coil

1 600-turn coil for use on 240V AC mains with shielded plug, fused protection and mains lead terminating in moulded mains plug.

All the coils are wound on high impact and thermal resistant material bobbins with insulated casing and are wound using enameled copper wire. All the coils are fitted with 4mm socket terminals except for 600 turns coil for AC mains use. The number of turns and the direction of winding is marked on each coil. The clamping base is provided with an arrangement to firmly hold the U-core and provides for easy changeover of the coils. Soft-iron pieces locate on top of the U-core arms. One end of each pole piece is flat so that the pole pieces in situ provide a narrow gap with full cross-sectional area, while the other end is in the form of a truncated cone giving a narrow concentrated field between the poles. With Instruction Manual. Other accessories also available on demand.

Optional Accessories:

Induction Accessories Set: Comprises a six-turn copper coil to show the production of a heavy current at low voltage by the melting of a nail, a solder trough to demonstrate the principle of induction furnace and a set of aluminum rings to show ‘Thomson’s ring’s effect. Two rings are ‘solid’, the third split to show that the rings must be continuous for ‘levitation’ to take place.

Motor Accessories Set: For demonstrating the effects of eddy currents, and the principles of shaded-pole motor. Comprising a pair of quadrant shaped eddy-current plates, one plain, one slotted and an aluminum motor disc with pole-shading piece. A vertical support rod fits into the hole provided in one of the transformer pole pieces and itself carries two transverse holes with clamping screws to accommodate the spindles of the quadrants and motor disc.
