Expectations for Model Based Development
- What do you expect from JMAG-RT in the future?
Representative from the Motor Manufacturer Currently it is a trial and error process where customers provide feedback,
such as "these results were good, but we would like a little more
here." If our customers can test the exact specifications by operating
the motor in the product that is being developed, such as the Sanden Corporation
and other customers who are using JMAG-RT, they can be more specific about
their needs. For instance, "there is no problem with the motor in
the steady state, but there is a problem when overloaded or light loaded."
This increases the speed of development because we quickly receive the
exact specifications and feedback from our customers. Because JMAG-RT has
these various benefits, it is a convenient tool to support the needs of
our customers quickly. Moreover, we can confirm whether or not there is
any irregular movement in addition to whether or not the back EMF is accurate
for the motor because the JMAG-RT behavior model is so accurate. I would
like to use JMAG-RT to determine whether a motor is right based on the
specifications we receive from our customers the first time around.
Mr. Hirono For the Sanden Corporation, we plan on using JMAG-RT to confirm the parameters
of a motor first. We currently receive the LdLq data from the representative
of the motor manufacturer, but it is difficult to apply the information
and explanation we receive because the results vary with the materials
and current that are used. Therefore, first we would like to evaluate the
parameters of the motor. In the future, we would like to evaluate the motor
parameters, and then perform a coupled analysis of the compressor, motor,
inverter, and inverter control. However, the challenge is determining how
much of an analysis can be utilized under time and cost constraints. In
the past, the control designer needed to understand the motor characteristics
to some degree to use the motor effectively in the design, but JMAG-RT
allows the control designer to use a motor in simulations without understanding
the motor characteristics. I have also come to realize that JMAG-RT also
accurately simulates the effects of high harmonics. We can continue the
development of the control by determining that a motor is not right even
without a prototype. We can cut costs by reducing the number of prototypes
as well as, of course, reducing the time and labor required to examine
those prototypes. These benefits are huge for us.
