Mitsubishi Electric has launched its next generation of
servo systems, offering safe, user-friendly and energy-efficient motion control.
"We are strong believers in developing 'technology with respect.' Some people really exaggerate, and put
servos all over the place.
So during your 30-hr/42-day primary
servo inspection, eyeball the
servos for everything that sequence 6.5 of TM 1-1520-237-PMS-1 tells you to.
In the family lineage, William is recorded as William
Servos as no middle name for William was known.
High-pitch ballscrews and high-torque
servos combine for rapids of 1,200 ipm Y and Z and 900 ipm X.
ELAU, Schneider Electric's packaging automation specialist, has expanded its range of Intelligent
Servo Modules.
Joseph Drilling, president of MPS North America Sales & Service, Milford, OH, says that top managers at converting companies are hearing the buzz about
servos and are sending their operations people to him to examine MPS presses, which are manufactured in the Netherlands by Multi-Print Systems.
At NPE, one more supplier introduced linear
servo drives on its traversing robots.
Hybrid presses, said to offer the best qualities of electric
servos and hydraulics without their disadvantages, are also coming into their own.
One new model employs the latest linear
servo technology in a cost-effective hybrid with standard
servos on two of the three main axes.
And economical ERCEA models for 28 to 300 tons have AC vector drives, said to be nearly equal to
servos in speed and precision but much lower in cost.
Although robot makers are still debating the pros and cons of linear
servos, there seems to be general agreement that linears are capable of faster acceleration, higher overall speeds, and greater position accuracy and repeatability.
Nissei and at least one other electric-machine builder are investigating another kind of electric motor--the linear
servo. Linear
servos utilize a stationary coil and a movable magnet to convert electromagnetic forces directly into linear motion.
Star Seiki is not the first robot maker to utilize linear
servos. At least two European suppliers are said to be doing so, and Mark 2 Automation in Germantown, Wis., came out with linear-servo robots last summer.
