Miniature voice coil servo motor features high force-to-size ratio, 1-micron resolution
Moticont’s new miniature GVCM-016-019-01M linear voice coil servo motor is smaller in diameter than a U.S. dime. This 15.9 mm (0.625 in.) diameter servo motor, also called an electric cylinder, features a high force-to-size ratio of 1.5 N (5.3 oz) continuous force and 4.6 N (16.6 oz) of peak force. The compact housing is just […]
Programmable linear actuator features stroke to 100 mm
The new LDL Programmable Electric Linear Actuator from SMAC Moving Coil Actuators has been designed as a cost-competitive alternative to pneumatics. A common trend in industrial automation is that engineers are looking for electric alternatives to pneumatic components for a number of reasons, including increased control, improved cycle life, and reduced operating cost. The LDL […]
Comparing micropositioning and nanopositioning stages
Linear stage designs can range from long-stroke, high-load gantries to micropositioning and nanopositioning stages with light payloads. Although all linear stages are designed and constructed to provide high positioning accuracy and repeatability and to minimize angular and planar errors, stages for micropositioning and nanopositioning applications require additional considerations in component selection and design to achieve these […]
What are piezo flexure stages and how do they work?
Piezo actuators provide highly responsive, rapid movements, but their displacement is limited to just 0.1 to 0.2 percent of the actuator length. To overcome this limited stroke capability, a piezo actuator can be combined with elements, such as flexures, that provide mechanical amplification. The amplification provided by a flexure mechanism can extend the stroke of […]
What are piezo actuator creep and drift?
Piezo actuators exhibit a linear* relationship between applied voltage and displacement, responding almost instantly to any change in voltage. But they also experience creep — a phenomenon in which the actuator continues to expand or contract even after the voltage change is complete. Piezo actuator creep Creep occurs because piezoelectric materials have an asymmetric charge […]
