Housing Outside Diameter, 0.750 inch, 19.1 mm

Product Overview

The GVCM-019-032-02VAC 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 Construction

The actuator provides a 0.875 in (22.2 mm) stroke, 7.4 Oz (2.1 N) of continuous force, and 23.3 Oz (6.5 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 0.750 in (19.1 mm), and the housing length is 1.250 in (31.8 mm).

Key Features

• Vacuum-compatible version for motion inside vacuum systems
• Integrated shaft and bearing for guided linear motion
• 0.875 in (22.2 mm) bidirectional stroke
• 7.4 Oz (2.1 N) continuous force
• 23.3 Oz (6.5 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

Applications

Semiconductor 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 Integration

Select 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 Control

The 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.
 
The miniature GVCM-019-032-02VAC Linear Voice Coil Servo Motor has only three-quarters of an inch (19.0 mm) in diameter and features a 0.875 in. (22.2 mm) stroke.

Also called an electric cylinder, this miniature linear servo motor, features a continuous high-force-to-size ratio of 7.4 ounces (2.1 N) and 23.3 ounces (6.5 N) of peak force at a 10 percent duty cycle.

Featuring: High reliability, high speed, zero cogging, high acceleration/deceleration, and when used in a servo loop, very high accuracy, and repeatability, these non-commutated, brushless miniature linear servo motors are clean, and quiet.

The housing is only 1.250 in. (31.8 mm) long and combined with coil end the total length is 1.438 in. (36.6 mm). In the fully extended position, the threaded shaft extends 1.156 in. (29.4 mm) beyond the face of the housing and the end of the shaft has a 2-56 UNC-2A thread 0.156 in. (4.0 mm) long for backlash free connections.

Both the housing and coil ends of the actuator have two 4-40 UNC-2B threaded mounting holes on 0.313 (7.9 mm) bolt circles for easy integration into an application, they should be considered as low-cost replacements for pneumatic linear actuators.
