Consider the two-pole motor shown in Figure 16.10 on page 778. The gap between the rotor and stator is 1.5 mm. Each of the two field coils has 250 turns and carries a current of 3 A. Assume that the permeability of the iron is infinite.
a. Determine the flux density in the air gap.
b. Each armature conductor carries a current of 30A and has a length of 0.5 m. Find the force induced in each conductor.
