  • Precision Actuator Puts New Spin on Solar Power
    Hydraulic drives bolster solar field's efficiency, reliability. Twenty-five miles south of Las Vegas, Nevada Solar One, a new 64-MW solar thermal power plant, recently went online. Spanning more than 300 acres, it 's the world 's third largest solar-energy field and will generate approximately 129
  • Hybrid Ultra-High Precision Positioning Actuators
    The combination of "coarse" precision screw drives for long distance motion and ultra-high resolution actuators such as piezo and voice-coil-based systems allows combining travel ranges up to hundreds of millimeters with response, smoothness and resolutions not achievable with conventional drives
  • Precision moves with pint-sized motors
    Innovative actuators and stages based on piezoelectric materials give superfine motion in a compact package. A typical use for PZT actuators is in the precision positioning of microscope objectives. The MIPOS 500 stage (top) from Piezosystem Jena Inc. is one example of a device designed
  • Soft Actuators for Hard Applications
    Today's inflatable actuators deliver longer strokes - up to 2.5 in. - and many can exert uniform force over their entire stroke. For the right application - typically single-acting, repetitive, short strokes, where positional precision is not required there are many advantages
  • Straight talk on selecting linear actuators
    New technology in linear actuators, antibacklash techniques, and piezo motors helps designers field high-precision motion equipment. Linear actuators come in a variety of shapes and sizes, with variable stroke lengths and a range of load capacities. Depending on type, electromechanical linear
  • Precision Moves With Magnetostriction
    Magnetostrictive actuators originally developed for sonar may prove useful for producing movements measured in micrometers. A cross-sectional diagram of a typical Terfenol-D actuator reveals the Terfenol-D rod, permanent magnets, and coil driver. Magnets bias the Terfenol-D magnetic domains for ac
  • Linear actuators achieve precision motion control with little to no backlash
    Roller-pinion systems are a better option than rack and pinions where accuracy and a minimum of friction are important.
