Heason Offers Air Bearing Positioning Stages

Through its distribution partnership with motion specialist Dover, Heason Technology offers precise air bearing positioning stages, including the MAB-100 single-axis linear-motor-driven stage. With a 100mm travel range, nominal overall accuracy within one micron and a choice of resolution options from five microns to five nanometres, the compact MAB-100 eliminates the unwanted motion characteristics that are associated with contacting bearing systems such as friction and hysteresis and delivers precise positioning with straight-line motion, high stage stiffness and rapid dynamic performance.

Aimed at nanometre-level positioning applications in life sciences, data storage, semiconductor and other market segments where excellent motion performance is essential, the MAB-100's non-contact brushless servomotor features a moving magnet design that, together with the fixed linear encoder read head, eliminates the need for wear-prone moving motor cables. The non-contacting motor, encoder and bearing set enables clean-room operation and ensures a long working life with minimal maintenance, contributing to a good cost of ownership proposition for advanced manufacturing or research alike.

The MAB-100 is also available as the Smart Stage HRC version that includes a high-performance servo drive and motion controller. The fully integrated assembly adds less than 60mm to the overall stage length and requires only a 24VDC power supply and an RS232 serial connection for configuration as an intelligent slave to a host computer, or as a programmable standalone controller capable of auto-running sophisticated motion sequences. Both versions of the MAB-100 include over-travel limits and end stops and the linear encoder includes provision for a home position to auto-datum the stage on power-up.

The complete Dover range spans medium- to high-precision-grade linear and rotary positioning stages that include both air and mechanical bearings with linear and rotary servo drive technologies, from single-axis ballscrew-driven tables to multi-axis gantry systems. Heason works closely with Dover and a small selection of global distribution partners to provide a range of motion control components in combination with its own in-house design and assembly capability.

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...

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...

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.
