##### Abstract:

Technology at present needs faster and easier means of controlling equipment with few numbers of components. One of such equipment is the direct current (DC) motor, whose speed is directly proportional to the supply voltage. Using this established relationship between the speed and the supply voltage, this paper investigates the effects of different loads and inputs on the output response of the armature controlled direct current motor. The aim is to establish relationship between the speed of DC motor and the load torque at different voltages as well as investigating the performance of closed-loop systems when different voltages are applied to the armature circuit of the motor when a constant voltage is supplied to the field circuit of the motor. The study was carried out in two stages. The first stage involved mathematical modeling of the system while the second stage centered on the simulation of an armature controlled direct current motor using Simulink environment in MATLAB. The performance analysis of the modeled system shows that usage of feedback enhances the performance of the transient response of the armature controlled DC motor. In addition the result obtained shows that at different input voltages, the speed the DC motor is inversely proportional to the load torque.
