Automation of mine load hoisting with asynchronous drive
Authors:
Abstract
When automating mine load hoisting with asynchronous drive the main difficulties arise usually at the end of hoisting, when static resistances variable in magnitude and sometimes in sign are combined with low speeds.In order to obtain relatively rigid mechanical characteristics of the drive, necessary to ensure a stable low speed during the movement of lifting vessels in unloading curves, several methods have been proposed and partially tested in recent years.
