This system's NEMA17 high-torque, brushless motor design uses innovative techniques to control current flow through the motor, reducing resonance throughout the MDrive's speed range and making it quieter. It can take a broad input voltage range from +12 to +48 V dc. It runs at an extended operating range of -40 to 85C, and its general purpose I/O, running to +24 Volts, has been expanded from 4 to 8. The MDrive17 has a full-featured, easy-to-program instruction set, a 10-bit analog input, 0-5 MHz step clock rate, and 20 microstep resolutions up to 51,200 steps per revolution. Expanded features make electronic gearing possible with an output clock generated fixed to the internal step clock, or by following a rotary or linear axis at an electronically controlled ratio. Options and accessories include a long life linear actuator; encoders; integrated planetary generator; control knob and linear slide.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
