6.8mm High Precision Ultra Thin Flat Voice Coil Motor For Medical Devices
Product Description:
SUPT’s VCAP0020-0068-00A is an ultra-compact, ultra-thin flat voice coil motor designed specifically for medical devices, portable instruments, and microelectromechanical systems (MEMS). Housed in an ultra-compact enclosure measuring just 39 × 50 × 21.5 mm, this product delivers a peak thrust of 20 N, a continuous thrust of 5.5 N, and a stroke of 6.8 mm. With a thickness of just 21.5 mm, this flat voice coil motor is ideal for space-constrained applications such as minimally invasive surgical instruments, portable diagnostic devices, micro-pumps, and precision wearable mechanical devices. Manufactured using biocompatible materials and high-precision components, it delivers smooth, quiet, and stable motion with zero backlash and excellent repeatability. With a maximum operating voltage of 8.2 V, this flat voice coil motor features low power consumption, low heat generation, and a long service life. Thanks to its back-EMF constant of 4.4 V/m/s, the motor enables precise and responsive motion control. Widely trusted in medical robotics, portable optical devices, micro-valve control, precision medical device delivery systems, and small consumer electronics, this flat voice coil motor is the ultimate solution for micro-precision motion in ultra-thin designs.
