Series 4400 ELECOM II(TM) brushless motors are featured in a brochure. Detailed information is provided on the following subjects: standard features such as long life, smooth operation, and high responsiveness; construction including three-phase slotless stator, four-pole rotor with neodymium iron boron magnets, and six-step commutation at 60 electrical degrees; and motor and winding parameters. Additionally, the publication includes engineering drawings of standard and customized motor assemblies. Graphs illustrate motor speed versus torque.
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.
