Analysis, simulation, implementation and results of a new kiln drive system consisting of two AC motors of 315 kW each, on an existing common tooth gear, as a new contribution for the operational optimisation of rotating kilns, are presented in this study. Two separate inverter units control the two asynchronous motors with a common rectifier. This study also illustrates how backlash problems on tooth gear and maintenance needs are eliminated while reducing operational costs, down‐times and energy consumption, by applying contemporary technology, including power electronics and dynamic performance in control systems.
