Question

write two methods of increasing the RPM of a dc motor​

Answer 1

Explanation:

Thus, the speed of a DC motor can be controlled in three ways:

Thus, the speed of a DC motor can be controlled in three ways:By varying the supply voltage.

Thus, the speed of a DC motor can be controlled in three ways:By varying the supply voltage.By varying the flux, and by varying the current through field winding.

Thus, the speed of a DC motor can be controlled in three ways:By varying the supply voltage.By varying the flux, and by varying the current through field winding.By varying the armature voltage, and by varying the armature resistance.
