### Q.Due to magnetic saturation, the flux per pole in a dc machine without brush shift

• AIncreases in both the generators and the motors with load
• BIncreases in both the generators and the motors with load
• CIncreases in generators but decrease in motors with loads
• DDecreases generators and increases in motors with load
Correct Answer : (B)

Increases in both the generators and the motors with load

Hints :

Due to magnetic saturation, the flux per pole in a dc machine without brush shift Increases in both the generators and the motors with load.

Torque developed in an electromechanical energy conversion device depends upon

In electromechanical energy conversion devices (e.g generators and motors) a small air gap is left between the stator and the rotor in order to
