Wimshurst Generator

Название Продукция: Wimshurst Generator
модель: PE019

Подробно о продукте: Wimshurst Generator

Demonstration Unit
Designed as an affordable alternative to more expensive Wimshurst machines, this student-quality model features nickel-plated conductors for producing sparks up to 6 cm long under appropriate conditions.
The stand, Leyden jars, pulleys and handles are all formed from durable plastic; the sturdy base is made from laminated wood.
The Wimshurst machine is a historical electrostatic machine for generating high voltages, and was developed by British inventor James Wimshurst (1832 – 1903). It is an electrical generator with a distinctive appearance, having two large contra-rotating discs mounted in a vertical plane, and a spark gap formed by two metal spheres.
The machine belongs to a class of generators called influence machines. These generated electric charges by electrostatic induction, or influence. Earlier machines in this class were developed by Wilhelm Holtz (1865 and 1867), August Toepler (1865), and J. Robert Voss (1880). They were more efficient than the earlier machines that worked by friction. The earlier machines exhibited a tendency to suddenly and without warning switch their polarity. The Wimshurst machine did not suffer from this defect.
The machine is self-starting, meaning that it requires no electrical power supply to create the initial charge. It does, however, require mechanical power to turn the discs. The output of the machine is a constant current. The spark energy can be increased by adding a Leyden jar, which is an early type of capacitor suitable for high voltages.
