Aerotech's PRO-LM series of direct-drive, brushless linear servo motor driven stages now includes a new 280mm wide version, available in eight travel options from 300mm to 1.5m, for high throughput and heavy load precision positioning applications in harsh industrial environments. The side-sealed/hard top and fully protected stages feature heavy duty linear motion guide bearings, submicron level encoder feedback and optional cable management, and are now available in nominal widths of 165mm, 225mm and 280mm, which may be freely mixed to optimise application load and travel requirements.
The new competitively priced PRO280LM is built upon the successful side-sealed design that Aerotech has developed over several generations of linear motor and ballscrew driven stages. The aluminium hard top cover, finished in a protective scratch resistant hard coat, is a much preferred alternative to soft fabric or plastic bellows stage covers, especially for applications such as laser machining. The vertical tensioned side straps fully seal the internal stage components from machining or process debris. A wide selection of optional tabletops with steel inserts allow X-Y, XZ or YZ configurations with other PRO series stages with orthogonality certified to 5 arc-secs. Tabletop plates are also available for Aerotech ADRS, ADRT and AGR series rotary stages or to suit customer workpiece mounting in metric and inch hole patterns. Cable management is available for single axis up to customer specified XY, XYZ and XYZ+Rotary stage configurations.
The PRO280LM has a positioning resolution of 250nm from a choice of 0.1µm line driver or amplified sine output encoders. Other impressive specifications include HALAR calibrated accuracy to +/- 3µm for the 1.5m travel version (+/- 2µm for the 300mm travel stage) with speeds to 2m/s and acceleration to 3g. With complementary high specifications for stage flatness, pitch, yaw and roll, and with a maximum horizontal and side load capability to 150kg, the PRO280LM is well placed for heavy duty industrial applications where no-compromise manufacturing quality and fastest production throughput are of primary importance.
