280mm-Wide Stages For Positioning Applications

Aerotech has introduced a 280mm-wide version of its Pro-LM series of direct-drive, brushless linear servomotor-driven stages for precision positioning applications in harsh environments. The 280mm-wide version - the Pro280LM - is available in eight travel options from 300mm to 1.5m. 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 mixed to optimise application load and travel requirements.

The Pro280LM is built on the 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 an alternative to soft fabric or plastic bellow 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 selection of optional tabletops with steel inserts allows X-Y, X-Z or Y-Z configurations with other Pro series stages with orthogonality certified to five 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 0.1-micron line driver or amplified sine output encoders. Other specifications include HALAR calibrated accuracy to +/-3 microns for the 1.5m travel version (+/-2 microns for the 300mm travel stage) with speeds to 2m/sec 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 suitable for heavy-duty industrial applications where no-compromise manufacturing quality and a fast production throughput are important, according to the company.

Aerotech's brushless direct-drive linear servomotor technology ensures smooth motion with exacting speed control and precise in-position stability, allowing the Pro280LM to be equally effective for scanning or step/repeat applications or for compound axis contouring. The use of non-contacting motors and feedback encoders combines with long-life wiper sealed linear motion guide bearings for a rated meantime-between-failures life of 20,000 hours with low maintenance. Aerotech manufactures advanced motion controls that optimise the performance capability of the Pro-LM series with motion-specific and machine-interfacing commands.

These include the Position Synchronised Output (PSO) command that completely synchronises real-time multi-axis position with laser firing, camera capture, data acquisition or non-destructive-testing triggering to produce high-quality parts or ultimate accuracy test procedures, with minimal cycle times and fast production throughput. The company's advanced controls include setup, diagnostics and features that reduce position errors, improve settling times and provide other production and commissioning time-saving benefits. Aerotech's motion systems include motor power and encoder cables plus performance- and calibration-related documents. Complete machine frames and bases can be included in the scope of supply.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
