High-performance medical-grade DC high-speed blower WS7040AL: the core power driving precise respiratory support
In the medical equipment and industrial automation sectors, efficient and reliable airflow control solutions remain key to technological innovation. Wonsmart's WS7040AL series DC high-speed blowers, with their superior performance and sophisticated design, are ideal for medical respiratory equipment, 3D printing, and industrial cooling systems. Combining cutting-edge motor technology with intelligent control logic, this product is redefining the application boundaries of micro blowers.
1. Technical Architecture and Core Parameters
The WS7040AL utilizes a three-phase brushless DC motor drive system, combined with an NMB ball bearing design, achieving a perfect balance of high speed and low noise. The 12V model, for example, boasts a maximum speed of 42,500 RPM, generating a robust airflow of 19 m³/h at 0 kPa pressure, while maintaining stable output at a static pressure of 5.5 kPa. The 24V version further optimizes energy efficiency, achieving peak output power at a load of 4.5 kPa through 100% PWM control, while maintaining a maximum static pressure of 6.0 kPa.
This series of products is CE and RoHS certified, featuring an all-metal centrifugal impeller and a high-temperature-resistant ABS plastic housing. They operate stably in ambient temperatures ranging from -20°C to 50°C. The motors boast a mean-to-failure time to failure (MTTF) exceeding 20,000 hours (at 25°C). They weigh only 80-134 grams, significantly outperforming traditional brushed motor solutions.
2. Precision Application in the Medical Field
In the field of respiratory support equipment, the WS7040AL demonstrates irreplaceable technological advantages. Its compact design (60mm × 60mm × 40mm) and low vibration make it a core component for CPAP and bi-level positive airway pressure (BiPAP) devices. By integrating with smart sensors and microcontrollers, the blower achieves pressure regulation accuracy of 0.1kPa, ensuring personalized airflow support for patients during different respiratory phases.
In emergency medical scenarios, the WS7040AL's fast response (startup time < 50ms) and high reliability are particularly important. It supports dynamic overtemperature protection and short-circuit diagnostics, automatically triggering safety mechanisms under extreme operating conditions to prevent equipment failure and potential harm to patients.
3. Diversified Adaptation of Industrial Scenarios - Focusing on 3D Printing
The WS7040AL is suitable for a variety of 3D printing scenarios: it provides directional airflow for accelerated cooling in FDM printing, helps create a clean, constant-temperature environment for resin printing, and ensures balanced heat dissipation for industrial-grade multi-extruder equipment. Its low noise level is ideal for laboratory environments, and its modular design allows for flexible integration with various printing equipment.
4. Intelligent Control and Energy Efficiency Optimization
The WS7040AL built-in brushless motor controller integrates multiple intelligent functions:
- Dynamic load compensation : By monitoring changes in airflow resistance in real time, the drive voltage is automatically adjusted to ensure stable output power.
- Health status diagnosis : Through Hall sensors and temperature probes, 12 key parameters such as motor speed and bearing temperature are uploaded in real time to support predictive maintenance.
In terms of energy efficiency, the WS7040AL boasts a power factor exceeding 0.95, saving over 40% energy compared to traditional AC blowers. For example, in a typical medical device application, the 12V model consumes only 28W at full load, significantly lower than similar products.
Conclusion
The WS7040AL series of DC high-speed blowers is not only a culmination of micromotor technology but also a model of cross-disciplinary application innovation. Its dual breakthroughs in precision medical control and efficient 3D printing provide a new path for miniaturization and low-power development in smart devices. With continued advancements in materials science and control algorithms, the WS7040AL is expected to expand its technology into new energy, aerospace, and other fields, becoming a core engine driving industrial upgrading.
