Which of the following equation best represents the mutual inductance between stator and rotor in a single phase cylindrical rotor synchronous machine? (where θr= space angle between stator and rotor field axis)

Which of the following equation best represents the mutual inductance between stator and rotor in a single phase cylindrical rotor synchronous machine? (where θr= space angle between stator and rotor field axis) Correct Answer Msr=Mmaxcosθr

In a single phase cylindrical rotor synchronous machine, the Msr is maximum, when θr=0, and is zero when θr=90° and cosine function represents it.
