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.
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.
