Series of miniature servoamplifiers are for dc and brushless dc motors and incorporate custom mixed analog/digital ICs and a hybridized power stage. The basic configuration is a current mode amplifier, and no trimmers are used in the basic version. The products meet UL508c and the relevant CE regulations. The power stage is implemented on a single ceramic substrate, and this design enables high thermal conductivity, high current carrying capacity, and mechanical strength.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
