e/Ward Leonard control

Information
has gloss	eng: Ward Leonard Control, also known as the Ward Leonard Drive System, was a widely used DC motor speed control system introduced by Harry Ward Leonard in 1891. In early 1900s, the control system of Ward Leonard was adopted by the U.S. Navy and also used in passenger lift of large mines. It also provided a solution to a moving sidewalk at the Paris Exposition of 1900, where many others had failed to operate properly. An outstanding contribution to the war effort was with the use of Ward-Leonard Control systems in antiaircraft radars. Connected to “calculators/directors” the automatic tracking motion in two dimensions had to be extremely smooth and precise. MIT (Rad lab) selected Ward-Leonard to equip the famous radar SCR-584, ca. 1942. *Until the 1980s, when the Ward Leonard control system started to be replaced by other systems, primarily thyristor controllers, it was widely used for elevators because it offered smooth speed control and consistent torque. Many Ward Leonard control systems and variations on them remain in use.

has gloss	hun: A Ward Leonard-rendszer hazánkban elsősorban villanymozdonyok Ward Leonard-meghajtásaként ismert, mint a váltóáramú energiaellátás átalakításának egy módja az egyenáramú fogyasztók meghajtására. Valójában ez csak a felszín, az egyik lehetséges alkalmazás. A rendszer mélyén egy sokkal általánosabban is felhasználható, igen szellemes műszaki elv van.

Dutch
has gloss	nld: De Ward-Leonardschakeling was voor de opkomst van de thyristor de snelheidsregeling voor gelijkstroommotoren, en in 1891 bedacht door de elektrotechnicus Harry Ward Leonard. Deze schakeling is een klassiek voorbeeld van een roterende omzetter en is tegenwoordig volledig verdrongen door vermogenselektronica aangestuurde elektromotoren.
