I have been trying to make use of any kind of a motor in my project. For this application, I need to drive my motor at exact constant speed (50rpsecond). The applied torque will be in turning direction of the motor and very very small (it can be even considered "zero Nm").
I already have a circuit, with DRV8825 stepper motor driver and NEMA17 stepper motor. I can reach the speed of the motor at 6 rps, however it is not enough.
If I use a DC motor does it start at constant velocity if every thing else remains the same or it increases gradually?
I am open to any suggestion.
Thanks in advance!
