MOTION CONTROL:Lin Engineering recently announced the release of its new and improved NEMA 17 Brushless DC (BLDC) motors, the BL17 line. These motors are best for applications that entail high speed and high dynamic torque.
The BL17 line of BLDC motors provides quiet and smooth operation regardless of speed range; speeds of up to 4000RPM are easily attainable. The motors are available in four body lengths: 1.7, 2.4, 3.2 and 3.9 inch, and is capable of up to 106 oz-inch of peak torque depending on the stack size. These motors are also great for those who prefer velocity control with an analog input, do not need holding torque and may be having reliability issues with an existing Brush dc motor.
These motors can additionally be ordered with custom shaft and winding variations to meet exact speed/torque/voltage point.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
