1. a) Write the most common expressions that give the stored energy and induced electromagnetic torque of two windings within the mutual coupling. b) Give the induced electromagnetic torque expression of a switched reluctance machine having the winding current i, and winding self-inductance L11. c) What is the positioning of the armature and excitation field spaces in a DC machine? What is the advantage of this positioning for the researcher?

Q: Calculate the mesh current iz. Please enter your answer to 3 significant figures (i.e 0.123). ν1 =…

A:

Stator and Rotor Magnetic Field

The stator and rotor magnetic field is the resulting magnetic field generated by a system of coils that are symmetrically aligned. They are supplied with polyphase currents. The magnetic field is generated by poly-phase (two or more phases) current or single-phase current. In the latter case, two field stator windings are supplied and two resulting electromagnetic fields are generated beyond the stage.
