3-16 In Fig. P3-16, the stator coil has N, turns, and the rotor coil has N, turns. Each coil produces in the air gap a uniform, radial flux density B5, and B,, respectively. In the position shown, cal- culate the torque experienced by both the rotor coil and the stator coil, due to the currents i, and i, flowing through these coils. Show that the torque on the stator is equal in magnitude, but opposite in direction, to that experienced by the rotor. i, Tem is i, Stator magnetic axis Rotor magnetic axis Fig. P3-16 Problem 3-16.
