description Ányos Jedlik Overview
Ányos Jedlik was a Hungarian physicist, teacher, inventor, and Benedictine monk whose work contributed to the early development of electrical engineering. He built an early direct-current electric motor and developed a dynamo machine based on the principle of self-excitation. Jedlik is studied in histories of electromagnetism for these machines and for his role in the development of practical electrical devices in nineteenth-century Hungary.
help Ányos Jedlik FAQ
What did Ányos Jedlik invent or develop?
Ányos Jedlik developed an early direct-current electric motor and a dynamo machine based on self-excitation. He was a Hungarian physicist, teacher, inventor, and Benedictine monk.
When did Ányos Jedlik build his early electric motor?
Jedlik experimented with electromagnetic rotating devices around 1827 and 1828. His design used electromagnets, a rotating part, a stationary part, and a commutator, which are recognizable components of a modern direct-current motor.
What was Jedlik's contribution to the dynamo principle?
He developed an early unipolar generator and formulated the principle of electromagnetic self-excitation. A dynamo machine associated with Jedlik was built in 1861, although Werner von Siemens later patented a dynamo system in 1866.
Why is Ányos Jedlik important in the history of electrical engineering?
His work connected electromagnetic theory with practical rotating machines before electrical engineering became an established industrial field. He also taught physics and demonstrated electrical devices in Hungary, including work with batteries, motors, and generators.
