Motors & Drives

Aerotech's new ABRT series rotary stages combine innovative air bearing mechanics, direct-drive servo technology and ultra-high precision angle encoders to provide exceptional levels of angular positioning performance. Available in three models with nominal tabletop diameters of 100 mm, 150 mm and 200 mm, they provide up to 70 kg load capacity with bidirectional repeatability to less than 1 arc-sec (< 5 μradians) and calibrated angular accuracy to +/- 2 arc-sec.

Stepper motors fitted with flying leads often require elaborate and costly modification to adapt the wiring into applications, particularly where EMC, environmental protection or smart appearance is of importance. To address the problem, Mclennan Servo Supplies Ltd, the Surrey based mechatronics solutions provider has commissioned the acclaimed Japanese manufacturer Tamagawa Seiki to produce a new range of NEMA 23 and 34 frame hybrid stepper motors complete with a terminal block and a choice of cable gland or metal ring connectors.

A totally new concept in magnet design and construction has enabled Geeplus to develop a voice coil motor which develops between 30 and 40% more force than devices using a similar coil.

Claimed to be the world’s smallest closed loop nanopositioning system, the SL-1720-S available from Armstrong Optical of Northampton is the latest in a series of piezo stepper drive systems developed by SmarAct GmbH of Germany.

igus has extended its range of linear belt drive actuators with the launch of a smaller version of its DryLin ZLW drive.

Measuring just 13 mm in length and 46 mm in diameter but delivering an impressive 5 Ncm holding torque, Tamagawa’s TS3218 series flat hybrid stepper motors can provide a powerful miniature positioning solution in a very restricted space. Available from Mclennan Servo Supplies Ltd, these unique 200/400 step/rev motors are supplied in 5 V and 12 V versions for unipolar and bipolar drive connection with current ratings from 0.165 to 0.25 A/phase.

Claimed to be the world’s smallest bistable rotary solenoid, Geeplus have launched the tiny S1020 which measures a miniscule 2cms long and just 1cm in diameter. Designed for the operation of optical shutters or very light frictionless loads, the S1020 has a surprisingly fast operating speed of less than 4ms with a 10 degree operating angle.

The EZStepper was designed to allow the rapid implementation of stepper motor solutions in products requiring automation.

The EZ Piezo Servo was designed to allow the rapid implementation of Position Control using the Nanomotion** HR1-1-S3 or Similar Motor .

AllMotion Inc. announces immediate availability of its award-winning* dual axis EZHR17EN Stepper Motor Controller + Driver, designed for rapid off-the-shelf implementation in miniature applications.
