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.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
