The exhibit hall at the ABB Automation & Power World was
buzzing this week as attendees checked out some of the latest technology
offerings. Here's a rundown of two new product introductions at the show:
HDP Series AC Induction Servomotor
A major source of energy loss in a motor is due to the iron
loss associated with the stator winding. ABB's Fabrizio Galbiati says engineers
have addressed this problem in a new line of high performance, low voltage AC
motors with a low-loss lamination technology to achieve 95-96 percent
efficiency. More significantly, the HDP series motors, which come in a range of
sizes and power ratings from 2 to 270 kW, achieve comparable performance to
similar motors but with a smaller footprint. The result of a five-year
development effort, Galbiati says the design calls for 50 percent less material
and employs a cast aluminum rotor to achieve low inertia, features that ABB is
betting offset the 20 percent higher price tag than conventional motors.
Capable of operating at constant torque, the motor line is targeted at
applications such as extrusion machines and coil winders, which require high
torque at low speeds. ABB has also introduced a compatible drive for the motor.
Harmonics are a headache in motor operations, which can lead
to useful power wasted in the form of heat. While harmonics are typically managed
at the DC to motor point, ABB has come up with an alternative way of thinking
about the problem. "We basically found a way to take clean, sinusoidal power
and do something to it," says ABB's Peter Walker. Their solution is the Ultra Low Harmonic Drive,
which takes the same technology used to convert DC to the motor and uses it on
DC to utility power. "So instead of managing the harmonics that are introduced
in the process of converting AC to DC, we don't generate them in the first
place," he says.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
