Magneto: what is it and who invented it

(ORDO NEWS) — The boy, born in 1861 in the small German town of Ahlbeck, was considered an average student at school and showed an increased interest only in biology. But his father insisted that he become a mechanic, and motorists all over the world benefited. The boy’s name was Robert Bosch.

After graduating from the technical school in Ulm in 1879, Robert worked for several months as a coppersmith in the company of his older brother in Cologne, then gained experience in electrical engineering in the workshop of Wilhelm Fein (the inventor of the electric drill) in Stuttgart and studied the design of the first chain knitting machine in the jewelry company of Friedrich Rödiger.

He served in the army for a year, then went to the USA, where he worked in the Edison company, after which he moved to the UK and got a job in the company of the Siemens brothers.

In 1886, Robert returned to his homeland and opened the “Workshop for Precision Mechanics and Electrical Engineering” in Stuttgart. One of the orders he received was to repair the ignition system of a large stationary combustion engine at a Deuz factory.

Bosch took as a basis a system developed by Siegfried Markus – an armature with coils rotating in a field of permanent magnets generated an electrical voltage sufficient to create sparks that ignited the fuel mixture in the cylinders. The design proved to be successful.

And then the Bosch company made a real revolution. At that time, the ignition of automobile internal combustion engines was a real problem that each manufacturer solved in its own way.

The Lenoir version used spark ignition with high-voltage Ruhmkorff coils and power from galvanic cells, which were enough for a couple of tens of kilometers.

Robert Bosch’s experiments to improve the ignition system ended in a revolution in the automotive industry.

Bosch’s first experiments on the Beeston-Voiturette tricycle were unsuccessful: automobile internal combustion engines were much more high-speed (1000 rpm) than stationary ones. But in 1897, Bosch mechanic Arnold Zähringer made the anchor stationary by placing it inside a rotating metal cylinder.

This system (magneto) turned out to be so successful that the very next year Gottlieb Daimler began to install it on his cars (moreover, it was the only reliable system at that time).

And in 1902, another employee of the company, Gottlieb Honold, improved ignition by creating a high-voltage magneto and heat-resistant ceramic spark plugs.

Since then, the modest “Workshop” has become a giant corporation Robert Bosch, the largest manufacturer of a wide variety of automotive systems. Her famous ad reads:
