Hi, Can anyone help me to figure how to get 12V for the dc motor using 24V supply. I would like to use a 12V supply but that would mean some changes to the wiring. Instead of rewiring,I would like to just make do with the 24V supply. I will need a series resistor (ranging from 1k - 10k)so that I can control the current to the motor.Since the dc motor internal resistance is very small (approx 100ohms),putting them in series will not get me 12V.Putting another resistor in parrallel with the motor will probably require a very huge resistance. I thought of using zener diode in parallel with the dc motor but that will probably require the zener diode resistance to be greater than the motor coil so I can have most current going to the motor. Can anyone recommend any other solution to get 12V for the dc motor but at the same time a large current to goes to the motor? Thank you.
