Demonstraton Electric Bell

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
