MATHEMATICAL MODELING OF TRANSMISSION START WITH AN ASYNCHRONOUS ELECTRIC MOTOR

Cutting & Tools in Technological System, 2020
Найскладнішим моментом в роботі приводу з асинхронним електродвигуном є запуск. І чим потужніший привід - тим цей запуск складніший. Це пов'язано з певними особливостями асинхронних двигунів: обмеженого пускового моменту і пускових кидків струму ланцюга статора двигуна.
