WebMs is the stator mutual inductance. This value is the average mutual inductance between the stator windings. The permanent magnet flux linking winding a is a maximum when θe = 0° and zero when θe = 90°. Therefore, the linked motor flux is defined by: [ ψ a m ψ b m ψ c m] = [ ψ m cos θ e ψ m cos ( θ e − 2 π / 3) ψ m cos ( θ e + 2 ...
