GVCM-032-025-02 Linear Voice Coil Motor with Internal Shaft and Bearing
Stroke: 0.50 inch (12.7 mm), Continuous Force: 2.1 Lb (9.3 N), Intermittent Force: 6.6 Lb (29.3 N)

Housing Outside Diameter, 1.250 inch, 38.1 mm
The GVCM-032-025-02M 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. Also referred to as an electric cylinder, this compact linear servo actuator features a continuous high-force-to-size ratio of 9.3 N (2.1 lb.) and 29.3 N (6.6 lb.) 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 linear servo motors are clean and quiet. They are an ideal choice for: Haptic feedback, pipetting, medical devices, laser machining and drilling, work holding and clamping, scanners, laser beam steering and filtering, optical focusing, dynamic vibration absorption, testing, sorting, and assembly.
Product Overview The GVCM-032-025-02 is a brushless linear voice coil motor with an integrated shaft and internal bearing for guided, direct-drive motion. Its 1.250 in. (38.1 mm) housing provides a 0.50 inch (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. Performance and Construction The non-commutated direct drive design produces smooth bidirectional force proportional to coil current. With no gears, lead screws, or mechanical transmission components, the motor provides zero cogging, rapid acceleration and deceleration, quiet operation, and zero mechanical backlash when the load is coupled directly to the shaft. The housing length is 1.000 inch (25.4 mm). Key Features • Integrated shaft and internal bearing for guided linear motion • Direct-drive brushless operation with no cogging • Zero mechanical backlash when directly coupled to the load • Smooth, controllable force proportional to current • High acceleration, rapid reversal, and responsive servo performance • Compact cylindrical housing for space-constrained equipment • Threaded mounting and shaft features for straightforward integration Applications Medical and Laboratory Equipment: Haptic feedback, pipetting, diagnostic instruments, sampling, and compact test systems. Optical and Scientific Systems: Optical focusing, beam steering, shutters, scanners, and precision positioning. Small-Scale Automation: Sorting, switch actuation, light clamping, small-part assembly, and dynamic vibration control. Mechanical Integration and Closed-Loop Control The built-in shaft and bearing simplify load alignment and provide guided linear travel. For closed-loop position or velocity control, combine the motor with a suitable position sensor, servo controller, and current amplifier. Final accuracy and repeatability depend on the feedback sensor, load, mounting stiffness, controller, and servo tuning.
