Analyzing Transformers Using JMAG
(7) Other JMAG Features and Coupled Analysis
The results obtained from a transformer analysis can be easily used to
implemented coupled analysis with the thermal analysis solver and structural
analysis solver available in JMAG. Loss distributions caused by copper
loss accounting for the high frequency current distribution of the coil
as well as iron loss that has varying degrees of magnetic flux distribution
in the core can be captured accurately. A thermal analysis that accounts
for the effects of heat dissipation can be performed in addition to obtaining
vibration and noise using a structural analysis that accounts for the electromagnetic
force produced in each part. JMAG is simple when performing multiphysics
analyses encompassing the complicated physical phenomena that makes CAE
simulations superior.
(8) CAE Benefits the Design Process
Implementing CAE simulation into the design process benefits the design
process itself. The modeling process for CAE means the designer once again
considers and makes decisions about design specifications for the simulation.
The same process is accomplished when creating the plans and specifications,
but creating the simulation model requires that designers make decisions
based on more information. When designs are performed by creating plans
and specifications, a vastly experienced engineer has to review the plans
and specifications for designs, or they need to be examined using the actual
prototype to determine if there are any inconsistencies. Therefore, the
pros and cons of designs cannot be determine when the plans and specifications
are created.
However, designers can have a opportunity to more thoroughly investigate
their designs by implementing CAE simulations into the design process.
This results in a higher quality output that greatly benefits designers.
Designers Accumulate Experience.
The trail and errors undertaken by veterans can be experienced first hand
at a low cost because the evaluation process can be performed quickly and
high risk ideas can be attempted without the fear of failure.
Flush Out the Pros and Cons of a Design
Designs can be intuitively understood from their strengths to the causes
of problems and areas requiring reevaluated because phenomena that can't
be evaluated using a prototype, such as magnetic flux density and the flow
of magnetic flux, can be obtained in CAE simulations.

A license for the transformer analysis and solver is required with the
basic JMAG set to start using the JMAG transformer analysis function. The
frequency response magnetic field analysis solver or the transient response
magnetic field analysis solver, or both of these solvers can be implemented
as necessary.
