STMicroelectronics Motor Control Reference Design Kit consists of a control board and three power boards with ratings of 300W, 1 kW, or 3 kW. The control board uses the ST7FMC microcontroller, which is designed specifically for motor control applications. A dedicated graphical user interface and firmware libraries simplify configuration and customization. The separate power and control boards achieve high noise immunity. Designed for a range of three-phase applications, the inverter topology addresses ac induction motor, permanent magnet (PM) dc/ac or brushless (BL) dc/ac (six-step sensorless) control, and PMAC or BLAC (sinusoidal driven, with Hall sensors). The power switches consist of six IGBTs with short circuit rating at 10 µsec. The free availability of the OrCAD source files enables the use of the physical design of the boards in the target application.
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.
