actually its a challenge from my friend.They want me to do such things.Initally i thought to use a dc generator with the shaft of the motor and calibrate the output voltage with speed.output of this generator is converted to digital and comapre with desired speed.but don't how to implement it.So...
Need help in controlling the speed of DC Motor ??
Can anyone of genius mind here tell me how to control the speed of dc motor in four quadrant operation automatically without using microcontroller or PLC ??
I Want to do a mini-project where i want to setup a speed from a keyboard input so...
