Question:

In the paragraph preceding Equation 8.1, the text states that "under the assumption of negligible iron reluctance the mutual inductances between the phases of the doubly-salient VRM of Figure b will be zero, with the exception of a small, essentially constant component associated with leakage flux." Neglect any leakage flux effects and use magnetic circuit techniques to show that this statement istrue.
