Question ans 7.427 Nm and 12.47 solve only if you get this answer otherwise you will get downvote ЗА For the doubly-excited system shown in Fig. 10.7, the inductances are approximated as follows: 4 =11+3 cos 20 H; L2 =7+2 cos 20 H; M=11 cos 0 H The coils are energized with direct currents I =0.7 A, 12 =08 A (a) Find the torque as a function of e, and its value when 0 =-50. (b) Find the energy stored in the system as a function of e.
