MOTION CONTROL:Siemens introduces new flavors to the 1FT7 family, a line of high-performance servomotors for such demanding motion control applications as machine tool CNC interpolation, production machine web handling and more. Their use results in shorter machine cycles due to higher dynamic response, gained through a 30 percent shorter design and 4x overload capacity versus 3x on the predecessor family of servos. Less downtime results from the new rigid vibration-insulated encoder mounting. This design also enables the OEM or end-user to exchange the encoder in the field in less than five minutes, without encoder alignment. High-resolution encoders, currently up to 22-bit, enable these servos to become highly precise motion control system components.Start-up and commissioning personnel will appreciate DRIVE-CLiQ, the Siemens electronic nameplate and digital encoder interface on this new servomotor. It simplifies start-up or replacement by not requiring manual parameterization of the axis, as the drive reads all that data from the electronic nameplate stored in the encoder system. With this feature, these motors become essentially plug-and-play devices. The drive automatically recognizes the motor and optimizes the parameterization accordingly. This digital encoder interface further allows users to standardize on one signal cable type for all the different feedbacks offered with the 1FT7 motors.
The new flavors added to the family are forced ventilated and water-cooled types, complementing the convection air-cooled 1FT7’s. In addition, a new high dynamic design is now available. This design features very low rotor inertia, thereby making these motors practical in applications where it was previously impossible to drive a servomotor. Such applications include sorters in the printing industry, which previously required mechanical cams, but can now utilize electronic cams for better energy efficiency and less wear.
With these new features, design engineers have a choice in selecting the optimum motor for their application within one single servo motor family - the Siemens 1FT7.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
