Answer 1

Answer:

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.

Answer 2

Answer:

here it the answer mate

State two ways by which the speed of rotation of an electric motor can be increased.

Magnetic flux - By decreasing the flux, the speed of the motor can be increased. ...

Resistance of the armature circuit - By decreasing the resistance, there is increase in the armature current which causes a larger torque to be developed
