II. Product Features
1. High-precision positioning: With the subdivision drive technology, the step angle can be accurately controlled between 0.01° - 1.8°, ensuring that medical equipment can achieve micron-level precise positioning in scanning, injection, sampling and other operations, avoiding errors affecting diagnosis and treatment effects.
2. Low-noise operation: With optimized motor structure and silent bearing design, the operating noise is less than 40 decibels, creating a quiet atmosphere for the medical environment, not interfering with the patient's emotions and the work of medical staff, especially suitable for noise-sensitive operating rooms, wards and other scenes.
3. High reliability and long life: The use of wear-resistant and corrosion-resistant high-quality materials, combined with sealing design, can effectively resist the erosion of disinfectants, body fluids and other erosions in the medical environment; after 1000 hours of continuous trouble-free operation test, it ensures stable performance under long-term high-frequency use and reduces the frequency of equipment maintenance.

4. Flexible control performance: supports multiple control methods, and can realize forward and reverse rotation, speed regulation, positioning and other operations through control systems such as PLC and single-chip microcomputer to meet the diverse motion control needs of different medical equipment; it has a power-off self-locking function to prevent equipment displacement in the event of an accidental power outage, ensuring safe operation.
