DC Motor Control, Radio Frequencies


The aim of this paper is to design an effective, efficient and low cost microcontroller based control unit that will be used to wirelessly control a DC motor using RF (radio frequencies) at distances ranging from 100 meters. The user should be able to wirelessly control the DC Motor. To achieve this, the digital circuit will be interfaced to a microcontroller 8051. An electronic technique called Pulse Width Modulation (PWM) is used to generate High and Low pulses (duty cycles) that vary and thus control the speed of the motor. The generation of this pulse is made possible by using a microcontroller (SST89E516RD) which in turn sets the speed ranges as per each cycle. H-Bridge was also used to achieve direction control (clockwise and counter clockwise direction) and an RF module, a small electronic circuit used to transmit, receive radio wave where transmitter transmits the signal while receiver receives the signals that have same range of frequencies. This paper is practical in the economic view and hence gives a reliable, durable, accurate and most efficient way of a DC motor control.
