The Sanden Corporation which designs, develops, and sells inverters for
automobiles is planning motor based development using JMAG-RT models for
control simulations by creating behavior models based on a proposal from
one of their motor design manufacturers. Mr. Hirono and Mr. Tsukamoto,
in charge of the design and development of inverters from the Electronic
Development R&D Division, Mr. Sekine, in charge of evaluating motors
from the Power Electronics Device Group, as well as a representative from
the motor manufacture who proposed JMAG-RT to the Sanden Corporation, discuss
the benefits of using JMAG-RT.

Focusing on Enhancing Performance for Compressors in Hybrid Vehicles
- What kind of product development is the Sanden Corporation focusing on?
Mr. Hirono Our job focuses mainly on cooling and heating. The field of heating and
cooling can be roughly broken into distribution systems for vending machines
and refrigeration display cases for supermarkets and convenience stores,
living and environment systems for EcoCute and wireless communication modems,
as well as the field we are responsible for, automotive systems. We specialize
in the design and development of compressors for air conditioners and HVAC
units. Presently, we are particularly focused on enhancing the performance
of electric compressors for environmentally friendly hybrid vehicles. Mr.
Tsukamoto and I are in charge of the motor control design of electric compressors
and Mr. Sekine manages the performance of motors.
Recently, the development speed to meet the requirements from our customers
is increasing. We are now often required to deliver products within two
or three months whereas, conventionally, we had a lead time of half a year.
The time allowed for development continues to get shorter. Unfortunately,
this means we have to constantly pressure the manufacturers that make the
motors we purchase for speed in addition to miniaturization and cost reduction.
- What is energy management?
Representative of the Motor Manufacturer My company develops motors as well as the peripheral devices of motors,
such as gears and control devices. In the past, our customers required
solutions to resolve energy conservation issues, or more specifically,
problems related to efficiency. However, today, especially from automotive
manufacturers, energy management is becoming a key word. Energy management
refers to managing the energy of the entire drive system so that no energy
is wasted. The design trends now require a design that not only simply
aims for a peak torque, but also reduces the loss in the various drive
regions. This means we can't just focus on the region that will be used
the most often, but rather, we have to improve efficiency and reduce losses
with a balanced design.
