This paper discusses about a development of simulation model for investigation the performance characteristics of AC drives applying to mine winder. Mine winders are designed to fit out the mine hoisting facilities that are installed in the vertical and sloping mine shafts that are used to transfer the load such as mineral resources and rocks. The driving source for this developed simulated model is by using synchronous motor and is developed using MATLAB/Simulink software. The obtained results of the simulation are analyzed and evaluate in order to be able to obtain the necessary information to predict precisely its operational performance characteristics. The understanding of these performance characteristics behaviors, particularly its dynamic characteristics are significantly important for design analysis. It provides vital information for selecting of precise design specifications and accurate prediction of performance characteristics of the developed drives system when operating over wide variation of load and speed characteristics. This subsequently will lead to the better understanding of operating the drives system at high optimum operating efficiency. Understanding the dynamic characteristics of its various parameters such as torque, current and speed is essential particularly during design process will ease the determination process of peak values of the various parameters and subsequently enable accurate prediction and selection of the design specifications of the system to be possible. Furthermore, the analysis performed from the obtained simulated results enables operational behavior characteristics of each parameter to be determined. From the reliability of the developed model enhance to perform other similar simulations involving AC drives and motor.
