To overcome this challenge, Fujitsu has developed a technology that utilizes its Digital Annealer to calculate in a matter of seconds how to arrange each individual magnet to achieve maximum magnetic flux density
, delivering an efficiency gain of 16%.
To find the relations between the dimensional initial and mass-dimensional parameters, we represent the maximum value of the magnetic flux density
at a certain point of the winding as
It is inferred from the above study that reduction in rate of change of air-gap flux density
and increase in average value of air-gap flux during IC are necessary to reduce torque oscillation, improve magnet operating point and decrease losses during IC .
In the study, both 2D and 3D methods have been used to calculate electromagnetic parameters and the outcomes of 3D simulations, magnetic flux density
results are illustrated as shown in Fig.
Thermal neutron flux density
in a block of paraffin moderator was specified as part of the unpublished work .
This simulated cross section of the transformer reveals that the flux density
in the center leg was well below saturation.
Figure 3 shows a no-load 2-D air-gap flux density
distribution in the U and V concepts at two different field excitation levels: field-weakening at [I.sub.DC] = 5.0 A and at field without additional excitation at [I.sub.DC] = 0.
4) in order to study the magnitude of flux density
passing through steel plates.
During intense Sunspot activity, the solar flux density
and the apparent center of emission vary unpredictably.
From this, the unsteady temperature field and the unsteady heat flux density
field can be derived.
Stator and rotor currents and flux density
and all other electromagnetic variables have been obtained.
Here p is the hole density, [v.sub.y] is the carrier velocity in the y-direction, [[tau].sub.p] is the lifetime of holes, [alpha] is the absorption coefficient, [PHI] is the radiation flux density
, y is the distance from surface towards the substrate.
In addition, it is necessary to popularize the method with which problems can be studied by building simulation models because it is more convenient to change parameters and view the current density and flux density
which are not easy to achieve in practical experiments.
However, unlike the DC bias method, bias field from PM cannot be easily tailored, weaker magnets tend to fail their purpose while stronger ones drive GMM to saturation, and it is always challenging to find magnets of appropriate remanent flux density
, size, and shape.
There are different concepts for analytical models, each of which requires an accurate computation of the flux density
to calculate the torque.
