High Speed Linear Servo Actuators


IAI Product Overview

Product Description

Replacing the ball screw with no-friction magnets, the Linear Servo (LS) series magnetic linear actuator delivers exceptional repeatability at ultra-high speeds.

And if you are looking to dramatically reduce your cycle time, the LS magnetic linear actuator can accelerate or decelerate at an extremely fast 3G - much faster than even an advanced ball screw linear actuator.

Series Features

The Linear Servo Advantage
High Speed Linear Actuation
The LS linear actuators achieve a maximum speed of 3000 mm/sec. Unlike ball screw linear actuators, there are no critical speeds with the LS. Therefore, operating speed does not drop - even in long stroke applications.

Rapid Acceleration / Deceleration Able to accelerate or decelerate at up to 3G (29.4 m/sec2), the LS can dramatically reduce the cycle time for short distance travel.

High Repeatability The fully closed control, using a reflection-type optical linear encoder, ensures positioning repeatability on the order of ±10µm.

Dust proof Construction A stainless dust strip on top of the magnetic linear actuator prevents problems caused by the entry of foreign particles into the linear actuator, greatly reducing maintenance requirements.

Easy Operation The all-in-one controller combines a driver, control unit and power supply, so all you need to connect is a dedicated cable. The system will be up and running in quickly, without the need for time-consuming adjustments.

Choice of Controllers You can select the controller that's right for YOUR application and budget - the advanced X-SEL® controller for easy control of multiple axes or the single-axis E-CON controller designed specifically for simple positioning applications.


Linear Actuator Specifications

The Linear Servo magnetic actuators come in two basic types: Large and Small.

Both the large and small magnetic linear actuators have a minimum service life of 10,000km.
(Service life is rated at maximum speed and maximum payload. Reducing either can significantly increase the service life.)
