Question
A 480 V, 3-phase, 50 Hz, 6-pole, slip-ring, Y-connected induction motors has the following parameters: R3-R2-0.19 Ohm and Xeg-0.33 Ohm The motor speed at full load is 970 rpm. If the magnetizing current is neglected, calculate the maximum torque Answer: The main task of power electronics is to control and convert electrical power from one form to another form Select one: Oa. True O b. False The field and armature resistances of a 231V series motor are 0.1 ohm and 0.2 ohm, respectively. The motor takes line current of 32 A while running at speed of 700 rpm. If the total iron and friction losses are 428 W, determine the motor efficiency in percent. Answer:
