NEW MOTION CONTROL COMPONENTS AND TECHNOLOGY IN THE SPOTLIGHT!
"Gotcha Stick" from STI Features New Dimensions for Human Arm
Scientific Technologies, Inc. (STI), introduces the new "Gotcha Stick" Safe Distance Scale. This three-segment safe distance stick accurately tests the allowable barrier opening size based on the distance from the point of operation. It features English measurements on one side, and Metric measurements on the other.
Maxon Motor Introduces the EC-4Pole 32 HD Motor with Planetary Gearhead!
The new maxon EC-4pole 32 HD motor has been designed for extremely rough operating conditions, particularly applications in deep drilling. This 480 W motor can withstand 200 °C, 1000 G, -5000 m and 1700 bar.
Fall River, MA -- Deep drilling technology (called “downhole drilling” in the field of oil and gas exploration) makes it possible to recover oil and gas from depths of more than 2500 m. By combining deep drilling with directional drilling (dynamic position alignment of a bore in the earth), previously unreachable oil reserves are being opened up, with drilling depths of approx. 5000 m and drill lengths of up to 11000 m. The development of specialized electronics and drives has made it possible to better monitor and control many functions across the entire drilling process. For instance, it is now possible to dynamically measure and adjust the position of the drill head during the drilling process.
H2W Technologies Introduces XZ Brushless Linear Motor Positioning Stage!
Santa Clarita, CA - - Linear Motor Positioning Stage -- H2W Technologies introduces a high acceleration, brushless linear motor driven, XZ positioning stage gantry for controlled dual axis motion profiles of customer supplied payloads. The vertical axis dual rail stage (DRS) is a closed loop positioning system that can be used for high force positioning applications. The horizontal axis single rail stage (SRS) is a closed loop positioning system that can be used for low to medium force positioning applications. The stages are driven by brushless linear motors, guided by precision recirculating linear ball bearing blocks and rails. Each axis incorporates 1 micron resolution linear encoders. Dual shock absorbing dampers are incorporated into the stage to protect the stage and payload in the event of power failure.
Netzer’s New DS-25 Absolute Rotary Encoders Are Available With Analog Or Digital Outputs!
Woodbridge, Ontario, Canada -- Motion Control Encoders - Rotary Electric Encoders™ from Netzer provide exceptionally accurate, high resolution, absolute position with miniature to wide diameter hollow shaft and are available with analog or digital outputs.
The holistic structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings. The lack of bearings and components such as flexible couplers, glass disc, light sources and detectors, along with very low power consumption makes the DS-25 encoder virtually failure free.
Application Note - Microdrives Plumb the Oceans of the World!
Robust DC Motor Drives Deep-Sea Sensors
Clearwater, Florida - Research often means coping with extreme conditions to retrieve the right data. Marine research is a case in point. Underwater sensors that plumb the depths of the world’s ocean have to withstand not only temperature differences but also extreme pressures, yet still deliver reliable readings. Up until now, measuring devices secured to cables or hawsers have generally been used to record such data. This technique is proven and reliable, but the disadvantage is that the data does not become available until after the devices have been recovered. A different concept used in conjunction with state-of-the-art microdrive systems now allows completely independent recording by free-ranging underwater sensors and virtually online data transmission.
Coampre Black Racer Linear Bearings to Conventional Linear Ball Bearings and Ask for Your "Black Racer Squadron" Patch or Poster!
E. Longmeadow, MA -- Linear Bearings - Compare LM76's Ceramic "Black Racer" Linear Bearings with conventional linear ball bearings. At first glance, Black Racer linear bearings wipe the floor with linear ball bearings. However, linear ball bearings provide the lowest coefficient of friction for mechanical bearings - only surpassed by air bearings. Linear ball bearings are more compliant than sleeve bearings, thus they are more forgiving in applications where shaft parallelism is not exact. Linear ball bearings offer more self-alignment capability than sleeve bearings. Although Black Racer bearings are direct drop-in replacements for inch linear ball bearings, you should call LM76 to ensure your application is a good candidate.
12-48 VDC 400W Integrated Servo Motor Is Available from JVL!
Birkerød, Denmark and Morrow, OH (USA) -- Designed for battery powered and low voltage applications the MAC402 is now available from JVL, a leader in the field of integrated servo and stepper motors. The MAC402 is the VDC version of the popular MAC400 400W integrated servo motor. The supply range for the MAC402 is from 12VDC up to 48VDC, and full power of 400W (RMS) up to 1200W (peak) can be reached with 24 to 48VDC. This powerful, compact motor measures just 191mm (7.52 in.) x 60mm (2.36 in) x 114mm (4.49 in.) Applications include but are not limited to: Remotely operated robots, robotic vehicles, portable equipment, tracking devices, antenna mounts, and positioning devices.
Dual Axis Linear Steppers feature: Low Profile, Low Cost, and .00004” [1 micron] Microsteps!
Santa Clarita, CA -- Dual Axis Linear Steppers. -- H2W Technologies Dual Axis Linear Stepper Motors are ideal for open loop positioning applications with light payloads. They can be used at speeds up to 80 in /sec [2m/sec] and strokes up to 40” x 60” [1 m x 1.5 m]. Linear stepper motors are capable of very precise position, velocity and acceleration control when coupled with a microstepping drive and indexer.
The moving assembly called the “forcer” is supported by magnetically preloaded air-bearings imbedded in the active surface of the forcer between the forcer and platen. The bearings are designed to support the customer’s payload and to maintain the required .001” [0.025 mm] gap between the platen and the forcer.
