In a two phase cylindrical rotor synchronous machine, the mutual inductance Mαβ between α phase and β phase winding is __________
A. Mmax
B. 0
C. Mmin
D. any of the mentioned
Answer:A
In a two phase cylindrical rotor synchronous machine, the mutual inductance Mαβ between α phase and β phase winding is __________
A. Mmax B. 0 C. Mmin D. any of the mentioned
Explanation: Since the axes of phase α and phase β windings are normal to each other and air gap is uniform, the mutual inductance Mαβ between α,β winding is zero.
