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.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
