GVCM-032-076-02 Linear Voice Coil Motor with Internal Shaft and Bearing
Stroke: 2.50 inch (63.5 mm), Continuous Force: 1.8 Lb (8.0 N), Intermittent Force: 5.3 Lb (25.3 N)

Housing Outside Diameter, 1.250 inch, 38.1 mm
The GVCM-032-076-02M (Metric version), features a 63.5 mm (2.50 in.) stroke and a diameter of 31.8 mm (1.250 in.). This motor features very high accuracy and repeatability when coupled with a linear encoder in a servo position loop. This low inertia motor also referred to as an electric cylinder and moving coil motor, has high reliability, high speed, zero cogging, high acceleration/deceleration. This clean and quiet motor is ideal for use in lab, cleanroom, assembly, sorting, and manufacturing applications. This Linear Voice Coil Motor has a high force-to-size ratio of 8.0 N (1.8 lbs.) continuous force and 25.3 N (5.3) of peak force at 10% duty cycle. The internal M2.2X0.45 x 0.20 threaded 0.175 +/- 0.008 mm (0.125 +/- 0.0003 in.) diameter shaft enables a zero-backlash connection to the load. Two M3.5x0.6 x 0.20 threaded mounting holes on 12.7 mm (0.500 in.) bolt circles on each end of the motor allow for easy integration into new and existing applications. The overall length of this compact linear actuator is 152.4 mm (6.00 in.) long and the shaft in the extended position extends 66.7 mm (2.625 in.) beyond the housing. The shaft guided by a plain bushing tolerates a side load up to 2.0 N (7.2 oz.) The low cost, “Made in America” Linear Servo Motor is 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-032-076-02 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 2.50 inch (63.5 mm) stroke, 1.8 Lb (8.0 N) of continuous force, and 5.3 Lb (25.3 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 3.000 inch (76.2 mm). The internal bearing is rated for side loads up to 2.0 N (7.2 oz.). 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.
