Моделирование пуско-тормозных режимов тягового электропривода постоянного тока
(НТУ "ХПИ", 2010) Синолицый, Анатолий Филиппович; Филипп, Юлий Борисович; Максимов, Михаил Николаевич
In the article the flow diagram of hauling electromechanic of direct current is offered for research of starting and brake office hours. By means of computer design the charts of transients of current and speed are got.
Полупроводниковый шим-коммутатор для системы безредукторного привода пассажирского лифта на базе бесколлекторного двигателя постоянного тока с дисковым ротором
(НТУ "ХПИ", 2010) Бибик, Артур Витальевич
In-process talked about creation of 4-th quadrant semiconductor PWM – switchboard and three-contour system of adjusting, which together with the commutatorless motor of direct-current with a disk rotor it is possible to use in an lift gearless electric drive. It will allow to promote reliability, simplify service, and due to enhanceable coefficient of useful effect - to economize electric power in static and dynamic modes. The flow diagram of switchboard is resulted. The experimental oscillograms of voltage and current are presented.
