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
I have been asked this question in homework.
I need to ask this question from Elementary Synchronous Machines in chapter Basic Concepts in Rotating Machines of Electrical Machines
The correct option is B. 0
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.
