0.88N Micro Cylindrical Linear Voice Coil Motor For Medical Endoscope Lens Focusing

The SUPT MOTION VCAR0001-0064-00A is a miniature cylindrical linear voice coil motor specifically designed for focusing medical endoscope lenses, with a peak thrust of 0.88 N, a continuous thrust of 0.28 N, and a total stroke of 6.4 mm. With a diameter of just 9.5 mm, a length of 17.7 mm, and a voice coil weight as low as 3 g, this motor can be directly integrated into the slim body of an endoscope without compromising the device’s operational flexibility or patient comfort, making it the ideal drive component for medical endoscope lens focusing. This voice coil motor features a medical-grade non-magnetic stainless steel housing and biocompatible insulation materials, complying with the ISO 10993 medical device biocompatibility standard. It can be used directly in sterile surgical environments and is free of tissue irritation and toxicity. In terms of performance, the motor achieves a positioning accuracy of ±0.005 mm, a repeatability of ±0.002 mm, and a response time of less than 0.3 ms. It enables micron-level precision adjustment of the lens focal length, helping physicians quickly obtain clear images of internal organs and avoid diagnostic errors caused by focal length deviations. Additionally, the linear voice coil motor features a coreless winding design that eliminates the cogging effect, ensuring low noise during operation and preventing interference with physician communication or equipment auscultation during surgery. In terms of environmental adaptability, the voice coil motor operates within a temperature range of -5°C to 70°C, accommodating temperature fluctuations in medical environments; It features a high protection rating, withstanding alcohol wipes, ethylene oxide sterilization, and light water mist during endoscope disinfection, ensuring no performance degradation over long-term use. Operating at 6.9V with a power consumption as low as 0.8W, this voice coil motor meets the portable power requirements of endoscopes. It generates no heat, preventing excessive endoscope body temperature that could compromise the patient’s experience. Compared to traditional electromagnetic drive components, the VCAR0001-0064-00A features no mechanical friction, ensuring smooth and stutter-free operation. With a maintenance cycle of up to 3 years, it significantly reduces hospital equipment maintenance costs, providing a reliable, precise, and safe focusing drive solution for medical devices such as rigid endoscopes, flexible endoscopes, and arthroscopes.
