The medical equipment industry is subject to stringent global regulations, as products are directly related to patient health and safety. Consequently, the performance and reliability requirements for components are extremely high. With the development of precision medicine, minimally invasive surgery, and portable diagnostic devices, the demands on actuators have become increasingly sophisticated: 1) Extreme Low Noise & Vibration: Providing a quiet environment for patients and staff, and preventing vibration from interfering with precise measurements (e.g., imaging, bio-analysis). 2) High Precision & Smoothness: The motion of surgical tools, drug pumps, and scanning equipment must be precise and jitter-free, especially inhibiting pulsation in fluid control. 3) High Reliability & Long Life: Equipment failure can have severe consequences, requiring components to operate stably throughout their lifecycle, with materials needing to be biocompatible or sterilization-resistant. 4) Miniaturization & Low Power: Meeting the integration and battery-life needs of portable and handheld devices.
AKT Product Solution
AKT provides precision motion solutions for the medical field that meet industry standards, prioritizing Brushless DC Motors (BLDC) and High-Precision Hybrid Stepper Motors.
- Quiet, Long-Life & Clean Solution:
Our miniature, low-noise BLDC motors (e.g., 28mm, 42mm, 57mm series) are the top choice for medical devices. Through optimized electromagnetic designs (e.g., skewed slots, fractional slots) and high-precision bearings, we control their NVH (Noise, Vibration, Harshness) to extremely low levels. More importantly, the brushless nature of BLDC motors fundamentally eliminates the noise and carbon dust contamination associated with brush friction, making them the ideal choice for pumps and blowers in ventilators, anesthesia machines, and dialysis equipment, with service lives extending to tens of thousands of hours. - Precision Fluid Control Solution:
For applications requiring precise fluid metering (e.g., peristaltic pumps, syringe pumps), our BLDC motors or hybrid stepper motors offer exceptional control accuracy.
Stepper Solution: Our small stepper motors (e.g., NEMA 14, 17), by virtue of their step-by-step precision, combined with micro-stepping drivers, can achieve micro-liter level dispensing.
BLDC Solution: A BLDC motor paired with a small planetary gearbox and a dedicated driver can provide stable, smooth, and pulse-free rotational speed via high-accuracy closed-loop velocity control, ensuring the continuity and precision of drug delivery. - High-Precision Positioning Solution:
In applications requiring high-precision positioning, such as sample arms in biochemical analyzers or collimators in scanning equipment, our 0.9° high-resolution hybrid stepper motors are the ideal choice. Their step angle is half that of conventional motors, allowing them to easily achieve micron-level positioning accuracy and excellent low-speed smoothness when paired with a micro-stepping driver. - Engineering & Customization Capabilities:
We offer compliant customization for the medical industry, including: stainless steel or special coatings to withstand cleaning and sterilization, planetary gearboxes using food-grade lubricants, sealed designs with IP ratings, and custom electrical windings for low-voltage (e.g., 12V/24V) battery-powered operation.
Typical Application Equipment Examples
- Ventilators and Anesthesia Machines:
Their core turbine blowers or bellows pumps require motors with high dynamic response (for rapid pressure adjustment) and extremely quiet operation. Our high-speed, low-noise BLDC motors can reach speeds of tens of thousands of RPM, offering fast response times and minimal noise, ensuring both device performance and patient comfort. - Syringe and Infusion Pumps:
These devices demand the utmost stability and accuracy in flow rate. Our small stepper motors (e.G., NEMA 17 or smaller) with high-resolution drivers and precision lead screws can achieve extremely slow and precise pushing. Alternatively, a BLDC motor + planetary gearbox solution achieves smooth, pulse-free delivery through closed-loop speed control. - Automatic Biochemical Analyzers:
The sample arms, reagent arms, and cuvette-washing arms in analyzers require high-speed, high-precision reciprocating positioning on multiple X-Y-Z axes. Our 0.9° high-resolution stepper motors paired with high-performance drivers provide a high-accuracy, high-speed, and low-vibration solution, ensuring high throughput and zero-error sample handling.
