This motor-generator set gives students an insight into the physical and technical relationships on which electric motors, generators and transformers are based.
The modular system allows to set up different function models without tools: Various DC motors Series and shunt motor Synchronous motor DC generator and alternator Transformer.
This set allows the performance of 10 student experiments about the following topics:
Magnetic field of a coil
Conversion of electrical energy into kinetic energy
Commutator
Direct current motor
Synchronous motor
Series and shunt-wound motors
Electromagnetic induction
The electrical generator
Engine-generator
Transformer
Wound on rectangular bobbin, for use with 220 – 240 V AC mains with detachable mains connector with moulded plug, A 4 mm socket is provided for earthing.
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
This heavy duty demountable transformer can be used for the study of transformertheory and many other alternating current phenomena.
This kit consists of:
1. A magnetic circuit made of highly permeable U shape metal sheet, which can be closed using two clamps with tightening screws.
2. Section: 40 x 40 mm with 150 mm length and 170 mm height.
3. One coil of 6000 turns with maximum current of 0.2 A. Intermediary coil of 2000 turns output.
4. One coil of 600 turns with maximum current of 2.5 A, which is mainly used to create the primary of transformer.
5. One coil of 1200 turns with maximum current of 1.25 A, fitted with intermediary 400 and 800 turns outputs.
6. One coil of 72 turns with maximum current of 12 A, fitted with intermediary 6, 30, 54 and 66 turns outputs.
7. Power supply cable.
For Westminster Electromagnetic Kit giving 1 V full wave rectified DC and 1 V / 2 V AC outputs at 8 A max.
The circuit diagram is printed on the top panel which also carries mains switch, light indicator and output sockets for DC and AC With 1.5 meter mains detachable cable.
A simple form of D.C. motor with 2 pole armature wound with insulated copper wire and a permanent magnetic field provided by a removable bar magnet with a commutator and phosphor bronze brushes connected to 4 mm sockets, open construction, all parts visible.
