Abstract
1. Токосъемное устройство для электрических машин, состоящее из двух коллекторов с чередующимися рабочими и холостыми токопроводящими ламелями и составных щеток, части которых расположены на обоих коллекторах и подключены к общей токопроводящей шине через активные сопротивления, отличающееся тем, что холостые ламели на коллекторах отсутствуют, к их рабочим ламелям присоединяется m-ходовая волновая обмотка якоря, а части щеток имеют ширину А контакта с коллектором, удовлетворяющую следующему условию: ! , ! где βк - коллекторное деление; Δ - толщина изоляционной прокладки коллектора. ! 2. Токосъемное устройство по п.1, отличающееся тем, что при использовании его в машинах постоянного тока средней и большой мощности без дополнительных полюсов активные сопротивления заменяются полупроводниковыми вентилями. 1. Current collector for electric machines, consisting of two collectors with alternating working and idle conductive lamellas and composite brushes, parts of which are located on both collectors and connected to a common conductive bus through active resistances, characterized in that there are no empty lamellas on the collectors, to An m-way wave winding of the armature is attached to their working lamellas, and the parts of the brushes have a width A of the contact with the collector, satisfying the following condition:! ! where βк - collector division; Δ is the thickness of the insulator strip of the collector. ! 2. The current collection device according to claim 1, characterized in that when it is used in DC machines of medium and high power without additional poles, the active resistances are replaced by semiconductor valves.
