improved EC 22 motors are equipped with preloaded ball bearings and latest-generation
Neodymium permanent magnets. They feature low vibration and low noise levels
even at high speeds. With their nominal torque of up to 44 mNm, an efficiency
of more than 90 percent and a 25 percent reduced speed/torque gradient, these
are truly performance-optimized drives.
All motors are available with Hall sensors or sensorless and
with up to four different windings. They can be combined with a variety of
standard gearheads and the sterilizable planetary gearhead in a wide range of
variations, as well as a servo amplifiers and positioning controllers.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
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.
