Calculate the following:
A dc, separately excited motor is driven by a full-wave, ac/dc SCR converter. The voltage on the ac side is 240 V (rms). The armature resistance of the motor is 5 ?. The armature current is continuous when a full-load torque of 400 Nm is applied. The motor speed under full-load torque is 100 rad/s, the motor efficiency is 95%, and the rotational losses are 105 W. Ignore the field losses. a. Output power of the motor b. rms voltage across the motor terminals c. Input power to the motor d. Losses in the armature resistance e. rms armature current
