It is difficult to evaluate the effect of the leakage flux
mathematically because it depends on various factors: the position of the windings relative to each other; the position of the windings in the transformer; the distance between the winding.
This particular arrangement considerably compensates both the side pull and skew leakage flux
sigma]] is the coefficient taking into the magnetic leakage flux
results in energy being alternately stored in and discharged from the magnetic fields with each cycle of the power supply.
Its advantage is to increase leakage flux
but also increase the q-axis inductance, the armature reaction and the polar angle, so that it reduces the electromagnetic torque.
This is increasing with load and multitude of sources, such as surface and slot conditions, leakage flux
, and another name is additional load losses, it should be 10%-20% of motor rating Stray load losses: [P.
The PMs are located in the leakage flux
paths, not in the main flux paths.
In the aligned position, the flux consists of the main flux under two poles and the leakage flux
beside the poles as follow:
At P5 the leakage flux
is substantial; while, the flux density in the middle of the air gap, point P6, reaches a local maximum.
The condition monitoring technique which would be suitable for the assessment of health and diagnosis of various faults of induction motor are axial leakage flux
monitoring technique and current monitoring technique.
As mentioned earlier, there should be minimum leakage flux
during the forward voltage scan (Lower Leak Flux: [[OMEGA].
There was a parameter giving the quantity of leakage flux
