The Melservo MR-J4 series of servo
amplifiers, complete with associated positioning units, easy to use motion modules and high end integrated motion control systems enable machine builders and end users to improve productivity and reduce energy costs.
Now we know what a servo
is, but by itself a servo
doesn't get much done--it must be part of a larger motion control system.
Credit for the introduction of servo
drives in narrow web presses goes to the Europeans.
Keep that in mind when inspecting the primary servos
' exposed pistons and internal seals on the hydraulic deck.
and Spindle High-Response Vector Software Version 4.
Following the overwhelming success of its iSH Series Intelligent Servo
Module technology introduced last year, ELAU has expanded the power range to handle applications such as main transport conveyors, carousels and other higher inertia mechanisms.
"One of the nice things about servos
is that they don't know or care which way they are running," says Spaulding.
Three other vendors of linear servo
robots--AEC, Hekuma, and Star Seiki of Japan (represented here by Star Automation)--did not bring them to the show.
Toshiba's new ECN series deserves mention because it uses ultra-high-speed linear servo
motors for faster injection with high positioning accuracy.
At the high end of price and performance is the linear servo
motor, which moves purely by electromagnetic induction.
New E-Series servo
robots from Engel Canada Inc., Guelph, Ont., are said to be more precise and compact than before, while offering substantial cost savings.
If the big show in Chicago was any indicator, linear servo
drives and jointed-arm designs may be the next trends in robots for injection molding.
