This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

Smart Motor Devices has improved the controller BMD-20DIN by expanding ways to control speed of DC motor – new device is now available at the industrial market TALLINN, ESTONIA, June 17, 2024 ...

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 ...
