A Matlab simulation of proposed system with no-load and full-load condition is performed on Simulink platform to observe the system response. The motor speed is kept constant in this experiment.

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

As a result of the efforts of Smart Motor Devices engineers, a cost-effective, full-featured and reliable controller BMD-20DIN ver.2 for DC brush motors is available now at the industrial market.
