so if i were to use a different motor (other pump components unchanged) to achieve the same rpm as the current motor, does it need to have the same torque?
In other words, are rpm and torque tie together, so that you would need the same torque to achieve the same rpm for any motor (other pump...
I have a dc motor geared to a diaphragm pump, and all hardware are unchanged.
As i increase the supplied voltage, rpm increases, but so does the current (torque).
I thought rpm increase would lead to higher back emf, and thus lowers the current. So would the only reason for my increased...
