• 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. |
