Short circuiting in the armature winding is caused due to
Any of the above
Short circuiting in the armature winding is caused due to Failure of insulation between two turns of a coil, Failure of insulation between two commutator bars and Grounding of two or more turns of the same coil.
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
