Roller Screw versus Ball Screw Actuators
In the ever-evolving field of engineering, roller screw technology has become a significant force in linear electric actuator motion control....
The unique NS linear servo actuator of IAI is composed of a ball screw which is fixed in conjunction with a rotary motor. The nut is mounted in a hollow shaft servo motor that is mounted in the carriage. As the nut rotates, and to transmit the spindle is stationary, it is possible long stroke lengths (up to 3000 mm), and to achieve high speeds (up to 2400 mm / s). The NS series is available in three sizes with a maximum load of 80 kg at speeds of 0.3 g or 24 kg with an acceleration of 1G.
Optionally placed two carriages each with its own motor with nut on a spindle. This makes it possible to combine two movements independent of each other on a single linear actuator.
Typical applications:
- Assembly systems
- Packaging machines
- Tooling machines
Stroke lengths up to 3000 mm.
Speed up to 2400 mm/s.
Acceleration speed up to 10 m/s2.
Optional:
Available single axis and multi-axis controllers for IAI NS electric linear cilinders:
The IAI actuators are deliverd with drive and cabling. Specifications of the actuator like forces and number of mm each revolution of the motor are already fixed. Because of this a a quick and safe commissioning is guaranteed.
The software engineers at ATB Automation assist in programming and commissioning via the help desk or on site
Besides control with I/O the drive can also be controlled with EtherCAT and ProfiNet.
The SD6 drive also has the CANopen option available.
We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.
In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
