The GVCM-032-025-02MVAC
Linear Voice Coil Servo Motor, the 12.7 mm (0.500 in.) stroke
compact linear servo motor with built-in shaft and bearing is just 31.8 mm
(1.250 in.) in diameter. The housing is only 25.4 mm (1.000 in.) long and
combined with the coil end the total length is 34.95 mm (1.375 in.).
In the fully extended position, the 3.175 mm (0.125 in.) diameter shaft
extends 15.9 mm (0.625 in) beyond the face of the housing.
The shaft has a M2.2X0.45 x 5.1 mm deep thread, and the housing and coil ends
have two M3.5X0.6 mounting holes on a 12.7 mm (0.500 in.) bolt circle for easy
integration into new or existing applications. |

Product OverviewThe GVCM-032-025-02MVAC is a vacuum-compatible, brushless linear voice coil motor with an integrated shaft and bearing. The self-guided moving shaft simplifies mechanical integration and provides smooth, direct-drive linear motion for equipment operating inside vacuum chambers and other controlled environments.Performance and Vacuum-Compatible ConstructionThe actuator provides a 0.50 in (12.7 mm) stroke, 2.1 Lb (9.3 N) of continuous force, and 6.6 Lb (29.3 N) of intermittent force at a 10% duty cycle. Its non-commutated direct-drive construction eliminates gears, lead screws, belts, and other transmission components, providing zero mechanical backlash, no cogging, rapid acceleration and deceleration, quiet operation, and long service life. The housing outside diameter is 1.250 in (38.1 mm), and the housing length is 1.000 in (25.4 mm).Key Features• Vacuum-compatible version for motion inside vacuum systems• Integrated shaft and bearing for guided linear motion • 0.50 in (12.7 mm) bidirectional stroke • 2.1 Lb (9.3 N) continuous force • 6.6 Lb (29.3 N) intermittent force at a 10% duty cycle • Brushless, non-commutated operation with no cogging • Direct drive with zero mechanical transmission backlash • High acceleration, fast response, and smooth force control ApplicationsSemiconductor and Vacuum Processing: Wafer handling, inspection, metrology, sample positioning, and vacuum-chamber automation.Optical and Scientific Equipment: Beam steering, focusing, scanning, alignment, spectroscopy, and research instrumentation. Aerospace and Test Systems: Space-simulation equipment, component testing, precision actuation, and controlled-environment mechanisms. Vacuum-System IntegrationSelect the motor, wiring, connectors, mounting hardware, position sensor, and controller according to the required vacuum level, cleanliness standard, temperature range, duty cycle, and allowable heat load. Thermal performance in vacuum differs from operation in air because convective cooling is reduced; continuous and intermittent operating limits must therefore be evaluated for the complete installation.Mechanical Guidance and Closed-Loop ControlThe internal shaft and bearing guide the linear motion, but the applied load should be aligned with the shaft to minimize side loading and bearing stress. For closed-loop position or velocity control, combine the motor with an appropriate external position sensor, servo controller, and current amplifier. Final accuracy and repeatability depend on the sensor, mounting, load alignment, structural stiffness, controller, and servo tuning. |
