TESS advanced physics set electric motor/ generator
Power supply 0...12 V DC / 6 V, 12 V AC, 230 Volt
Function and Applications Modular system for student experiments to work out physical and technical basic relations common to electric motors, generators and transformers. This system, which consists of single parts, allows to set up different function models. Following experiments can be carried out: ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪
Disassembling of an electric motor and examination of its components (stator, coil, rotary coil in the magnetic field, current inversion, brush contacts). Direct current motor with permanent stator magnets and rotating electromagnets. Alternating current synchronous motor Series-wound motor. Shunt motor. Alternating current generator. Direct current generator. Transformer.
Benefits ▪ ▪ ▪
Simple design of all components, so that the student can easily recognise their function. The possibility to set up function models gradually, so that functional relations between components can be understood. No tools required for assembly.
Equipment and technical data ▪
The system contains following parts: base plate, two pole pieces, permanent magnet, two coils, iron core, axle with current inversion, bearing carrier, two brush springs, two connecting cables with 2 mm plug pins, two reducing plugs for adaptation to the usual connecting cables with 4 mm plugs, brass driving axle, driving belt.
