On the use of a synchronous motor as the main motor in the system of the motor generator set with flywheel suitable to the mining hoist according to the system of Ilgner-Leonard

Abstract

The use of a motor-generator set with a flywheel (Ward-Leonard-Ilgner) as the main motor of a synchronous motor is dictated by the presence of a hydraulic coupling connecting the main motor shaft to the shaft on which the alternating voltage is located. Dynamo and flywheel installed. This clutch replaces the automatic flywheel slip controller, which operates at a constant speed of the synchronous main engine. This article describes the installation of a fluid coupling, as well as the idea of using it in a Ward-Leonard-Ilgner system with a synchronous main motor.
