SUPT has expanded its voice coil motor (VCM) range to nine production series, giving machine builders a single source for short-stroke, high-acceleration direct-drive actuators. The portfolio now covers cylindrical, flat (pancake), rectangular, arc, flexible feeder, shafted, semi-enclosed shafted, ventilator-grade and hollow-shaft (through-bore) designs.
- Cylindrical VCM - high response, high acceleration and low moving mass, with no cogging and zero hysteresis; widely used in semiconductor, precision test and valve flow control.
- Flat VCM - short stroke from 1 mm to 20 mm in a compact, low-profile envelope.
- Rectangular VCM - longer effective stroke, from 1 mm to 200 mm.
- Arc VCM - limited-angle rotary motion, 1 to 100 degrees of rotation and 1 to 50 N-m torque for mirror positioners and oscillating valves.
- Flexible feeder VCM - drives flexible vibratory bowl feeding for small or irregular parts.
- Shafted and semi-enclosed shafted VCM - integrated motion shaft and precision linear bearing for guided, ready-to-mount axes.
- Ventilator-grade VCM - lightweight coil, micro ball bearing system and flexible cable for respiratory equipment.
- Hollow-shaft (through-bore) VCM - an open bore for optical paths, probes or vacuum lines.
Cylindrical models in the VCAH series span 11 N to 253 N peak force with 7 mm to 24 mm total stroke. On selected voice coil linear actuators, repeat positioning accuracy peaks at 0.1 um - a specification that suits short-stroke, fast-response, high-precision positioning.
| Model | Peak Force (N) | Continuous Force at 25C (N) | Stroke (mm) | Voltage (V) | Back-EMF (V/m/s) |
|---|---|---|---|---|---|
| VCAH0011-0070-00A | 11 | 3.6 | 7 | 26.2 | 4.9 |
| VCAH0030-0100-00A | 30 | 7.2 | 10 | 24.9 | 5.2 |
| VCAH0040-0240-00A | 40 | 6.0 | 24 | 44.5 | 8.0 |
| VCAH0253-0120-00A | 253 | 46.5 | 12 | 42.7 | 16.0 |
Arc-series motors complement the linear range. The VARS family delivers 0.08 N-m to 0.42 N-m peak torque across 26 to 100 degrees of rotation, targeting laser mirror positioners, oscillating valve actuators, swing positioning systems and flight control applications in the semiconductor, automation and aircraft industries.
- No gearbox, screw or belt: zero backlash and no wear parts in the transmission chain
- No cogging and zero hysteresis for smooth, predictable force output
- High acceleration with a light moving coil for fast settling
- Maintenance-free operation and long service life
All nine series are wound, potted, machined and assembled in SUPT's 4,000 m2 plant under ISO 9001-2016 control, and each motor is verified on LCR, oscilloscope, thrust, pressure and interferometer test stations before shipment. Motors are modular by design and can be customised on force, stroke, winding, feedback, cable exit and mounting interface. Samples and 2D/3D drawings are available for engineering evaluation.
