Piezo Linear Actuator

Based on the Piezo Walk principle, the N-380/N-381 NEXACT® ceramic linear motor actuator from Physik Instrumente replaces classical lead screw actuators. It combines high forces and long travel ranges with sub-nanometer resolution in a small package. It provides 1 kg of push/pull force, 30mm of travel, and 10mm/sec speed.

DC Gearmotors

Designed for high torque, tight space applications, the FlexTorq™ 762 series hollow shaft offset DC gearmotors from Bison Gear & Engineering Corp., St. Charles, IL, feature either a 1.25in. (31.75mm) I.D. hollow shaft, or a 1.25in. diameter solid shaft in u-shaped or s-shaped configurations. Driven by 1/20, 1/4 or 1/2hp, 90Vdc variable speed motors, the gearmotors are available in nine standard off-the shelf models.

Speed Regulator

The Cushion-Start Kinechek® speed regulator from Deschner Corp., Santa Ana, CA, combines the shock absorbing feature of the company’s Cushioneer® shock absorber with the Kinechek® speed regulator. The impact-absorbing feature is a safeguard for those applications where a fast moving load exerts an impact force beyond the regulator’s capacity. Approximately 25% of the beginning of the stroke is used for cushioning, and then the remaining portion of the stroke will control the load with the same constant uniformity as a regular Kinechek.

Electric Actuator

The EGC electric actuator from Festo Corp., Hauppauge, NY, is designed for high dynamic speeds and high rigidity. It can be used as an individual component adapted to third-party motors, or as a complete system. The actuator is available with ball screw pitches in sizes 70, 80, 120, 185, and toothed belt pitches sizes of 50, 70, 80, 120, and 185. Due to the high performance and rigidity of the EGC, a smaller size actuator can be used to save both space and cost.

Linear Drive

The TA333 high-power linear drive from Trust Automation, San Luis Obispo, CA, combines a Class-AB linear amplifier with pure analog throughput at currents up to 25A. Highly configurable, the drive can be used with a brushless motor using external sinusoidal commutation, with an internally commutated brushless motor with Hall Effect sensor feedback for smooth trapezoidal operation, a 2-phase stepper motor, or up to two voice coil motors.

Product of the Month: Laser Beam Analysis System

Ophir-Spiricon (Logan, UT) has introduced BeamGageTM, a new laser beam analysis system. Based on UltraCalTM, Ophir-Spiracon’s patented baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy, BeamGage guarantees that the data baseline (zero-point reference) is accurate to 1/8th of a digital count on a pixel-by-pixel basis. BeamGage features BeamMakerTM, a beam simulator that enables users to numerically model expected results and confirm that the beam will be measured accurately. Beam-Gage also provides an Auto Aperture camera control function that allows for faster application setup.
