Solved Problem: DC Motor Problem 1 (Find Torque, Flux, Power Loss, Efficiency) TAGALOG
A 4 –pole, 240 V, wave connected shunt motor gives 11.19 kW when running at 1000 rpm and drawing armature and field currents of 50 and 1.0 A respectively. It has 540 conductors. Its armature resistance is 0.1 Ω. Assuming a drop of 1 V per brush, find (a) armature torque (b) shaft torque (c) flux per pole (d) rotational losses (e) efficiency. Ans: a. 111 N-m, b. 106.9 N-m, c. 12.9 mWb, d. 460 W, e. 91.4 %
