Current generation moves into wireless technology. Every one wishes to use remote controls. In this way, the speed of the DC motor is controlled by IR rays. IR rays get modulated with combination of data signal and carrier wave of 38 kHz. At the received end, the modulated signal is demodulated which is given to [...]

Now a days DC motors plays a vital role in most of the industrial areas, it can be seen in most of the electronic devices. They are mainly used for the mechanical movements of physical applications such as rolling the bundle of sheets or CD drives, lifts etc. Many methods evolved to control the revolution [...]
