Linear motion in medical applications: Voice coil actuators in ventilators
More and more, medical device manufacturers are replacing traditional components with smaller, lighter-weight options that have sufficient life and reliability for “life-critical” applications. One such example comes from manufacturers of ventilators, who are using voice coil actuators to control the valves that deliver air to a patient who’s unable to breathe on their own. Ventilators are […]
New 3-axis linear voice coil actuator stage from Moticont
Moticont has released a new three-axis XYZ linear actuator, the XYZ-10. The X and Y axis of the actuator each has 0.97 in. (24.6 mm) of travel and the Z axis has a stroke of 0.500 in. (12.7 mm). The high-speed, high-acceleration, zero-cogging, brushless voice coil motors provide 6.3 lb (28.2 N) of force and […]
SMAC actuators satisfy existing OEM form-fit-function requirements
SMAC now sells voice coil actuators that include differential features to satisfy OEM requirements … actuators that allow drop-in replacement of existing motion technologies having the same form, fit, and function. This design process is called MCA Inside and has been key in helping OEMs with an install base or an existing design to solve […]
Low-power voice-coil actuator for cryogenic environments
H2W Technologies’ new high-force, non-commutated dc linear actuator, otherwise known as a direct-drive voice-coil actuator, is designed specifically for use in cryogenic environments. Material choice and design parameters were implemented such that the motor can operate without degradation or damage when placed in a cryogenic environment. The model NCC14-78-830-1SM can generate a continuous force of […]
Physik Instrumente XY stage provides high speed and 10-nm resolution
Precision motion specialist Physik Instrumente (PI) now sells a new integrated XY stage — part of its compact high-speed positioning stage roster. All of these positioning stages are powered by ultrasonic piezo-linear motors — patented motors that deliver smooth motion, high resolution and rapid step and settle response. Also featured on the motors is a […]
SMAC single-axis servo controller starting at $200
SMAC Moving Coil Actuators has announced release of their next generation Very Low Cost (VLC) single axis DC brushed/brushless motor controller/driver. With a price of $250 for stand-alone ($200 for built in types) the VLC represents another 35% drop in price compared to many of the company’s previous controllers … and with no loss in […]
Electric actuators displace other motion options — including manual designs: A Motion Trends report
Today, electric actuators are easier than ever to specify and install. Value-add services from component suppliers as well as application-specific actuator product lines (especially for battery-powered designs in mobile equipment and consumer use) eliminate many integration tasks for OEMs and end users. These are trends supported in part by a movement Design World has tracked […]
New linear rotary actuator features 35-mm stroke with 5-micron encoder
The LCR16 from SMAC Moving Coil Actuators provides precision Z-theta motion within one small actuator, which is suitable for pick, orient and place applications. A wide variety of LCR16 linear rotary actuators are available with either direct drive or gearbox equipped rotary units. The vacuum-built-in shaft through the rotary motor is available for some models […]
New piezo driver with 1,200 W of power for fast switching applications
PI (Physik Instrumente) has released the new model E-619, a high-power piezo amplifier designed to drive high-capacitance multilayer piezo actuators with rapid rise times or high frequencies. As a special form of electro-ceramics, piezo materials are the gold standard when it comes to speed, force, and precision in a small package. Providing sink/source currents up […]
