Demonstraton Electric Bell

Description

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.

Description

With this simple electric motor model students can investigate the relationship between voltage supplied to rotor and polarity / position of magnets. On applying 6V DC to 4mm sockets, the rotor will begin to rotate across its vertical axis.

Description

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

Description

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
