Dunkermotoren launches compact linear motor with double peak force
With the SA/SC 38 series, Dunkermotoren presents a new modular concept for tubular linear direct drives. The highly dynamic three-phase linear motors deliver up to 3,690 N and accelerate at over 200 m/sec2. The modular design is currently available as actuator version SA (with maintenance-free plain bearing system) and component version SC (for modules). If […]
How to size a rack and pinion drive
In linear motion applications, ball screws are widely recognized for their ability to provide high thrust forces, while linear motors are gaining market share in high-speed applications, and belt drives continue to maintain their reputation as the best solution for long travel lengths. But rack and pinion drives are the often-overlooked workhorses behind gantry and […]
What are walking piezo motors?
Piezo motors that produce linear motion include linear ultrasonic piezo motors, linear stepper piezo motors, and piezo inertia motors. Although their construction and principles of operation are different, all three designs harness the inverse piezoelectric effect — in which a piezo material expands or contracts when electrical energy is applied — to produce linear movement in a […]
Under development: Linear stroke-extending technology from Ascending Power
In a recent email exchange with London-based John Hammerbeck of Ascending Power, we learned more about a novel new linear-motion extension technology from the company. The actuator steps up a short input stroke to a long output stroke using either kinematic linkages or permanent magnets. Below is a SolidWorks animation of the linkage variation; depending […]
Thomson online product sizing and selection tool for linear-motion systems
Thomson Industries has enhanced its Linear MOTIONEERING product -sizing and selection tool for linear motion systems. The tool reduces time for component selection from hours to less than 15 minutes. The upgraded resource also incorporates the RediMount motor mounting adapter kit — the default standard for Thomson linear motion systems and precision linear actuators. The […]
Compact voice-coil motors from Moticont with 1.0-in. diameters for myriad stroke requirements
Moticont now sells linear voice coil motors (LVCMs) in two 1-in. (25.4-mm) diameter motors. • The LVCM-025-022-01 has a stroke length of 0.375 in. (9.5 mm) a mid-stroke length of 1.30 in. (33 mm) and a high-force-to-size ratio of 16.9 oz (4.7 N) and a peak force of 53.5 oz. (14.9 N) at 10% duty […]
New SMAC LBL25 linear actuators — fast, cost-competitive, and stackable
SMAC Moving Coil Actuators now sells LBL series linear actuators — price competitive with ball screw and high-cycle-rate air cylinders thanks to a simple no-milling plate design. The LBL design features flat printed coil and single-piece, screw down magnets. It’s equipped with SMAC proprietary encoder and gives more than 100 million cycle expected life. Starting […]
ANCA Motion expands high-performance tubular linear motor line
The LinX M-series linear motor features an integrated position sensor with 10 um of resolution, eliminating the need for an external encoder, simplifying system design and reducing overall cost. Modular design of the heatsink and end-caps enables flexibility in system integration. The motor produces a continuous force range of 90 to 160 N and a […]
Belt-driven electric actuators from IMI Norgren offer precise control
A new line of belt-driven electric actuators from IMI Norgren is designed to meet the force and extreme loading requirements for machine builders and plant engineers looking for an alternative to pneumatic actuators. NB27 single rail belt-driven linear actuator features a unique arc belt technology that improves traction for higher thrust. These single rail actuators […]
