Problem-7 A permanent magnet DC motor has an armature resistance of 1 2 and when a voltage of 240 V is applied to the motor it reaches a steady-state speed of rotation of 40 rev/s and draws 80 A. Find the following; a) b) c) The power input to the motor. The power loss in the armature. The torque generated at that speed.
