An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum. He later replaced the globe with a glass tube of about 2.5 feet (0.76 m) emptied of air. [1] The glass tube was a less effective static generator than the globe, but it became more popular because it was easier to use. [2]
The Van de Graaff generator was developed, starting in 1929, by physicist Robert J. Van de Graaff at Princeton University, with help from colleague Nicholas Burke. The first model was demonstrated in October 1929. [7] The first machine used an ordinary tin can, a small motor, and a silk ribbon bought at a five-and-dime store. After that, he ...
An engineering drawing of a Wimshurst machine, from Hawkins Electrical Guide Wimshurst machine in operation Quadruple sector-less Wimshurst machine. The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903).
Owing to their simpler design, electrostatic types were the first particle accelerators. The two most common types are the Van de Graaf generator invented by Robert Van de Graaff in 1929, and the Cockcroft-Walton accelerator invented by John Cockcroft and Ernest Walton in 1932. The maximum particle energy produced by electrostatic accelerators ...
Van de Graaff was the inventor of the Van de Graaff generator, a device which produces high voltages. During 1929, he developed his first such generator, producing 80,000 volts. [6] By 1933, he had constructed a larger generator generating 7 million volts. [6]
Martinus van Marum's electrostatic generator at Teylers Museum. In 1779, he was entrusted with the care of the Second society left to Haarlem by Pieter Teyler van der Hulst (1702–1778), which led under his direction to the foundation of the Teylers Museum. The Teyler legacy was split into three societies, one for religion, one for science ...
The large electrostatic generator (Dutch: Van Marum electriseermachine) is a large handcrafted electromechanical instrument designed by Martin van Marum and built by John Cuthbertson in 1784 for the Teylers Museum in Haarlem, where it forms the centerpiece of the instrument room.
