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 […]
Multi-axis transfer robot features backlash-free belt drive
Bell-Everman has introduced a new multi-axis transfer robot based on its proven ServoBelt backlash-free belt drive technology. Called ServoBelt Arc Drive, it features custom designed rotary and tilt axes that precisely position semiconductor glass panels. Measuring 450-mm across, the robot’s large rotary axis is built around a ServoBelt drive mechanism and a proprietary Bell-Everman bearing […]
