DC Motors: Construction, Working and Applications

To convert electrical energy to mechanical energy (correct)

To regulate voltage and current in a circuit

To convert AC power to DC power

To convert mechanical energy to electrical energy

V = R*I + E (correct)

V = R*I + E + L*di/dt

V = R*I - E

V = R*I + L*di/dt

To change the direction of rotation of the motor

To increase the efficiency of the motor

To control the speed and torque of the motor (correct)

To reduce the losses in the motor
