In manufacturing industries like plastic, textile, chemical & pharmaceuticals speed control of DC motors is important for efficient and consistent production.
Depending upon the requirements & applications, the motor may be huge or small.Various DC motor drivers are available for speed control of these motors. There
are several methods for controlling the speed of DC motors. One simple method is to add series resistance using rheostat. As considerable power is consumed in the
rheostat, this method is not economical. As the method is to use a series switch that can be closed/open rapidly. This type of control is termed as chopper control. Here
we use a PWM based chopper that smoothly control the speed of DC motor. In this project we use DTMF generator (mobile phone) and the receiver circuit .Mobile
phone generate DTMF tones which is received by the another phone which feed the DTMF data to the DTMF decoder IC 8870 which produce the four digit binary
which is further feed to demultiplexer (4 to 16 line decoder).
