Moticont’s GVCM-051-025-01 Linear Voice Coil Motor features: High acceleration/deceleration, high speed, high reliability, zero backlash, high accuracy, high repeatability, and a 0.5 inch (12.7 mm) stroke length.  Also referred to as an Electric Cylinder, this linear actuator is an ideal low cost, high accuracy replacement for hydraulic and pneumatic linear actuators. This clean, compact, voice coil motor has a high force to size ratio with 5.3 lbs. (23.5 N) continuous force and 16.7 lbs. (74.4 N) of peak force at 10% duty cycle with a housing measuring just 2.00 in. (50.8 mm) dia. x 1.00 in. (25.4 mm) long. 

The precision ground 0.1572 (3.993 mm) diameter shaft has an internal thread, and the housing has threaded mounting holes on each end for easy integration into current and future applications.  This clean, quiet, efficient, low inertia, brushless actuator featuring an internal shaft and recirculating ball bearing is suitable for medical devices, antenna positioning, testing, sorting, assembly equipment, workholding and clamping, scanners and laser beam steering and filtering, laser machining and drilling, wafer handling, optical focusing, and dynamic vibration absorption. The Moticont’s GVCM-051-025-01 linear voice coil motor can also be ordered as a complete plug-and-play system including a position sensor, and controller. Is there a need for a smaller or larger diameter motor, one with longer stroke, or more force? 

There are currently seven series of Moticont's GVCM motors based on diameter of the motor, and models based on length of stroke and/or force to select from with additional motors being added to select from.
