Description

technical field [0001] The invention relates to a control system of an elevator, in particular to a switched reluctance control system of an elevator. Background technique [0002] Elevators are relatively complex mechatronic equipment that serve high-rise building transportation. Since the Otis Elevator Company of the United States manufactured the first elevator in 1889, in the past 150 years, a series of new elevators that integrate the latest scientific research achievements of human beings in the fields of machinery, electronics, optics and other fields have come out one after another, ensuring the safety of elevator operation. At the same time, it also endows high-tech performance advantages such as speed, energy saving, commendation, and capacity improvement. With the development of cities and the rapid increase of high-rise buildings, new requirements are put forward for the electric drive system of high-performance elevators. Passenger elevator traction machines i...
