I. Product Performance Parameters
The WS7040-12-X200 is a three-phase brushless DC blower designed for compact systems. Its core specifications include:
1. Electrical Characteristics
- Rated Voltage: 12VDC (recommended power supply: 12V-6A switching power supply).
- Current: 4.45A under fully open airflow, 1.5A in closed state, with static pressure up to 6.0kPa.
- Phase Resistance: 0.9Ω, optimized for efficiency and energy consumption balance.
2. Mechanical & Airflow Performance
- Speed: 35,000rpm (open state), 43,000rpm (closed state), adaptable to varying loads.
- Airflow: 416LPM (liters per minute) in open state; prioritizes static pressure in closed state for high-resistance scenarios.
- Noise: 65dBA, ideal for noise-sensitive environments.
3. Durability & Environmental Adaptability
- Bearings: Japanese NMB ball bearings with a lifespan of 10,000 hours (under 25℃ rated load).
- Protection Rating: IP20, operational temperature range: -20℃ to 50℃.
- Insulation Class: Class F, ensuring high-temperature resistance.
II. Core Features
1. Compact Design & High Efficiency
- Lightweight (68g) and space-saving, suitable for portable tools or space-constrained devices, delivering high vacuum pressure and airflow.
2. ntelligent Speed Control
- Compatible with external drivers (e.g., WS1208DY01V03), supporting PWM or 0-5V signals for stepless speed regulation.
- Hall sensors (60° electrical angle) enable precise speed control (1Hz ≈ 60r/min linear relationship) for stable operation.
3. Long Lifespan & Low Maintenance
- NMB bearings and brushless design minimize wear. Inlet filters further extend service life.
- Coil withstands 500VDC (1-minute test), meeting rigorous electrical standards.
4. Safety & Compatibility
- Standard industrial interfaces with clear wiring guidelines , simplifying installation.
III. Typical Applications
1. Medical Equipment
- Core component for CPAP (Continuous Positive Airway Pressure) devices, such as ventilators or sleep apnea machines, ensuring low-noise operation and reliability.
2. Industrial Automation & Portable Tools
- Integrated into handheld vacuum systems, 3D printer cooling modules, or pneumatic control units, meeting high-pressure and rapid-response demands.
3. Laboratory & Precision Instruments
- Used in spectrometers or environmental analyzers for airflow management, with IP54 protection for harsh lab environments.
IV. Selection & Usage Guidelines
- Power Compatibility: Use a 12VDC-6A power supply to avoid overload-induced failures.
- Operational Optimization: Avoid continuous operation at maximum static pressure; adjust loads based on airflow requirements.
- Maintenance: Regularly clean inlet filters and monitor bearings to maximize lifespan.
The WS7040-12-X200, with its compact size, high efficiency, and reliability, has become a critical component in medical, industrial, and energy sectors. As demand for smart systems grows, its tunable speed control and compatibility will further expand its role in IoT devices and automated control applications.
