# (Solved) For a rotational electromagnetic system consisting of a stator and a rotor, the stored field energy is given as

For a rotational electromagnetic system consisting of a stator and a rotor, the stored field energy is give as: If the inductance is dependent on rotor angular position, 8, then what is the expression for torque that can be derived from the equation above? For the rotational system shown below, the stator is energized by a de current of magnitude 4 A. If the inductance of the stator as a function of rotor position was given by Lss 0.4 0.2cos(20) H, what would the torque be for the three positions of the rotor shown in (a), (b) and (c)? Stator Stator Stator Rotor Rotor o Rotor (b) (c) θ= 90。 -45°
