Abstract


Analysis, simulation, realization and results of a new kiln drive system consisting of two AC Motors, 315 kW size each on an existing common tooth gear as a new contribution for optimizing the operation of Rotating Kilns are presented in this work. Two separate inverter units control the two asynchronous motors with common rectifier. Illustration of how backlash problems on tooth gear and generally other high cost and maintenance needs are eliminated together with reducing down times, energy and costs, by the application of modern technology power electronics and dynamic performance in control systems
