Cylindrical VCM Voice Coil Motor High Precision Light Weight Direct Drive

The VCAR0080-0129-00A is a cylindrical VCM voice coil motor engineered for high-precision, high-response positioning inside space-constrained automation. Unlike conventional drives that rely on gears, lead screws or belts, this moving-coil actuator converts electrical current directly into linear force, so a commanded move becomes motion almost instantly. The tubular coil glides inside a permanent-magnet stator with no contact between the moving and stationary parts, which removes backlash, friction and mechanical hysteresis from the motion path. Machine builders therefore obtain a smooth, quiet and repeatable linear axis that accelerates quickly and settles cleanly at the target position. With a low coil mass of only 149 grams and a compact 49 millimetre diameter, the VCAR0080-0129-00A fits neatly into optical heads, probe stations and miniature handling modules where every millimetre and every gram counts.

• Cylindrical VCM Architecture: The round coil and matched rare-earth stator deliver a high force-to-volume ratio, so strong thrust is available from a very compact cylinder.
• High Precision Positioning: Direct drive with an integrated position sensor supports sub-micron repeatability for inspection, metrology and optical alignment duties.
• Light Weight Moving Coil: A 149 gram coil keeps inertia low, enabling the high acceleration needed for fast step-and-settle cycles.
• Zero Backlash, Direct Drive: With no gears, screws or couplings, mechanical play and cogging are eliminated by construction rather than by adjustment.
• Fast Dynamic Response: Constant force-to-current behaviour lets controllers drive aggressive profiles for millisecond-level moves and rapid direction reversals.
• Low Noise and Long Life: Contact-free operation removes wear points and delivers an expected service life of 10,000 operating hours with minimal maintenance.

The VCAR0080-0129-00A is built for equipment where fast, accurate and repeatable linear motion drives throughput. Typical uses include optical focusing and lens positioning, wafer and semiconductor inspection stages, automated optical inspection (AOI) heads, miniature pick-and-place grippers, high-speed sorting gates and precision test probes that must step quickly between measurement positions. It is equally suited to medical imaging and laboratory instruments, where low noise, smooth motion and cleanliness are important, and to vibration-cancellation and active-damping assemblies that require continuous oscillation without wear. For original-equipment manufacturers, stroke limits, winding voltage, force constant and mounting interfaces can be customised to match a specific machine envelope.

Every VCAR0080-0129-00A is produced in a Jiangsu, China facility operating under ISO9001-2000 quality management and is bench-tested for force constant, insulation resistance and position repeatability before dispatch. The actuator is protected with anti-static foam and packed in an export-grade carton that resists shock during international shipping. The minimum order quantity is a single piece, which makes prototyping straightforward; samples ship in 3 to 5 working days and bulk orders in 15 to 25 days, with T/T as the standard payment term. A one-year warranty and application engineering support are provided, and the unit integrates directly with standard current-mode servo drivers designed for voice coil actuators.
