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 current be that the mechanical load increases as rpm increases?
