Escalator is useful and act in the important part to carry passengers to the targeted floors of building. Every escalator must be driven by its own motor and this motor speed must be controled. To drive escalator with a constant speed, direct torque control technique is used to drive three-phase squirrel-cage induction motor. In this paper, the development of speed control system for three-phase squirrel-cage induction motor using a direct torque control method is presented and simulation for proposed system is done with the help of MATLAB/SIMULINK.
