Explanation: The resultant MMF FR = 3/(2Fm) is directed along the axis of that phase, which carries the maximum current at that instant. 5. If the phase sequence of supply currents are reversed, then the direction of rotation of the resultant MMF wave will
A. Be reversed
B. Remains unchanged
C. Cannot be determined
D. None of the mentioned
Answer:A
Explanation: The resultant MMF FR = 3/(2Fm) is directed along the axis of that phase, which carries the maximum current at that instant. 5. If the phase sequence of supply currents are reversed, then the direction of rotation of the resultant MMF wave will
A. Be reversed B. Remains unchanged C. Cannot be determined D. None of the mentioned
Explanation: A reversal of the phase sequence of supply currents will reverse the direction of rotation of the resultant MMF wave. 6. Which of the following statements are correct regarding individual phase MMF in rotating machines ?
