Linear Motor Actuator: Series SL180 and SL250

		Key Features: •Modular design •Direct linear drive •High speed and acceleration •Fast settling time •Various strokes

The Direct Drive Linear Motor Actuator Integrated with Linear Motor that eliminates wear, friction, backlash and compliances associated with mechanical transmissions, such as ball/lead screws, rack & pinion, belts/pulses and gearboxes

Linear Actuator Benefits · No maintenance · High Positional accuracy · High stiffness · High positional accuracy · Compact mechanical assembly · Reduced parts count in the machine · Smooth velocity

Linear Motor Forcer
Brush-less Linear Motor features non-contact design resulting in no cogging for fast and accurate positioning

High Strength Aluminum Body
Extruded aluminum housing and precision machined to provide outstanding straightness and flatness for installations in horizontal or vertical orientations.

;

Carriage Support bearings
Precise Double rail bearing system is integrated into the linear actuator to support moving carriage and to provide dynamic stiffness and precise straightness of travel

Integral Linear Encoder
Precision non-contact linear position feedback with selectable resolution from 0.05 to 10 microns mounted in the carriage to minimize thermal drift

Limit Sensors
Stage has limit and home sensors to provide end of travel and “home” positions

Cable Transport Module
Cable track with high flex robotic cable is provided

Easy mounting
Housing T-slots and clamp down brackets provided

Multiple-axes systems

Gantry and XYZ robotic arms can be easily constructed using multiple Linear Motor Actuators

Highlights

Advantages of Linear Motors

• High repeatability – resolution to 0.000004 inch (0.1 microns) – this makes sure all parts produced are accurate and identical

• Highly accurate – to 0.0001 inch/ft (2.5 micron/300 mm) – provides precise machine operation for precision parts

• No backlash – direct drive has no backlash such as with lead screws, gears, etc. this improves the accuracy of the part or operation

• Faster acceleration – from 1 to over 10 G’s – this leads to shortened cycle times and improved productivity. • Higher velocities – speeds to over 300 inches/second (8 meters/sec) – to position the payload faster

• Long term reliability – only two parts with only one moving part – this leads to simplicity and improves the applications reliability

• No wear or maintenance – no contacting parts, thus reducing component friction and wear

• Ease of installation – linear motors are designed to allow for alignment tolerances. Misalignment produces no degradation of performance Linear motors consist of two parts – a stationary track or “platen” and a moving “forcer”. They can be provided as a stand-alone linear motor assembly or as a complete stage – built with a housing or enclosure with linear bearings, limit switches, cable track/carrier, protective bellows and linear encoder in a wide variety of lengths.
