The minimization of a salient pole flux leakage is one of the problems of DC and synchronous electrical machines design. The part of the pole flux loops through the air and does not reach stator or rotor. That is the leakage flux.
Let's calculate the flux leakage of a salient pole DC motor.
The flux leakage is the difference between the total and useful flux.
