Choose from Four Precision Linear Positioning Stage Technologies by HIWIN

Linear Motor Stages provide design engineers with additional choices when encountering applications that require highly dynamic movements and tight precision. Dropping in pre-designed and tested single axis stages saves engineers and technicians valuable design and installation time. This video will compare the performance capabilities of four popular technologies in iron-core and ironless core motion stages. You will also see additional accessories such as bellows and covers that are available as an option to add dust protection and safety to your real-world motion solution. HIWIN is a leader in high precision linear and rotational motion technologies used in automation and testing. Our wide product selection of both mechanical and electrical components allows the end user to eliminate multiple suppliers and use HIWIN as their single source of components.

    00:00:00 [Music] highwind has leveled its focus on precision linear stages by introducing updated technology that offers a wealth of benefits including higher accuracy higher speeds and less downtime for maintenance [Music] the lmxk is an economical solution but by no means does it fall short on

    00:00:25 performance topping out at 5 meters per second and 5 g's of acceleration the iron core motors utilized in this design can output a max continuous force of 308 newtons and a peak force of 868 newtons the iron core motor design has a high force density of 0.5 to 0.75 newtons per cubic centimeter giving it the best

    00:00:47 forced output within the smallest package size to avoid contamination hywind offers the option of an aluminum cover to protect the stage from large debris hyben also offers a bellows option the lmxk components are sourced machined and assembled locally meaning a lower lead time

    00:01:07 and the ability to customize per the application's demand the lmssa is a high precision upgrade to the lmxk with a custom extruded and machined base the machined mounting surface allows for a more controlled straightness and flatness specification the lmssa comes in two different base sizes which

    00:01:30 allows the design to incorporate larger sized iron core motors but also an option for ironless core motors due to the absence of iron ironless motors offer a lower force density however the velocity ripple is also reduced to 0.5 percent with zero cogging making delicate scanning applications

    00:01:50 smooth and easy for dust protection the ssa comes standard with the cover the design incorporates both top and side covers which help to prevent debris from entering and interfering with the guideways and motor in addition to the upgraded motor and base the lmssa offers three different encoder options a

    00:02:13 one micron resolution digital magnetic encoder a one micron resolution digital optical encoder and a 0.1 micron resolution digital optical encoder with a resolution of 0.1 microns hywind is able to achieve plus or minus 1 micron of repeatability the lmssa can achieve a stroke of up to

    00:02:34 2700 millimeters [Music] the nps or nano precision stage takes things up a notch and moves us from micrometers to nanometers these stages are ideal for when small incremental movement is needed and the precision constraints are narrowed down the two options for these stages

    00:02:56 are an ironless core motor or a precision ground ball screw with a minimum incremental movement of 100 nanometers and a bi-directional repeatability plus or minus 200 nanometers these are high winds most accurate standard single axis stages for an application which requires high accuracy over a wide work area

    00:03:16 we would need to move into our most advanced and dynamic linear motor system the diamond a granite base air bearing ironless core linear motor system this two-axis gantry stage uses a patented dynamic counterbalancing technology and mass compensation algorithm the dynamic counterbalance consists of an additional set of ironless core linear motors

    00:03:43 that actively eliminate the inertial forces with the dynamic counterbalance enabled the motion vibration can be reduced to approximately one lg in conjunction with the dynamic counterbalance the air bearings allow the axes to travel over the granite that has a flatness of approximately 0.75 microns

    00:04:04 without making any physical contact and providing ultra smooth motion the high wind control system matches the mechanical elegance by being able to provide approximately plus or minus 50 nanometers of repeatability and less than two arc seconds of difference in yawing from the gantry making the diamond

    00:04:21 the crown jewel of high winds linear motor systems whether you are looking for speed precision or a combination of both highwind has a solution to fill your linear motion needs for information about this and all highwinds products visit highwind.us or contact us
