Axial Stator. Normal stress occurs in many other situations besides axial tension and compression If an elastic bar with uniform and symmetric crosssection is bent in one of its planes of symmetry the resulting bending stress will still be normal (perpendicular to the crosssection) but will vary over the cross section the outer part will be under tensile stress while the inner part will be.
Different number of stator and armature fields as well as how they are connected provide different inherent speed and torque regulation characteristics The speed of a DC motor can be controlled by changing the voltage applied to the armature Variable resistance in the armature circuit or field circuit allows speed control Modern DC motors are often controlled by power.
