In a dc machine, the actual flux distribution depends upon
All of the above
In a dc machine, the actual flux distribution depends upon Size of air gap, Shape of pole shoes and Clearance between tips of the adjacent pole shoes.
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
