Industry Status Pumps and fans are core fluid control devices used widely in industrial (HVAC), medical, appliance, and automotive sectors. Driven by global “carbon-neutral” goals and rising energy efficiency standards, the core drivers of technological development are high efficiency and intelligent controllability. Traditional AC induction or PMDC (brushed) motors face bottlenecks in variable-speed performance, efficiency, and lifespan. For example, AC motor efficiency drops significantly during frequency conversion, while PMDC motor brush wear limits its life and creates EMI. Therefore, the Brushless DC Motor (BLDC), with its high efficiency, long life, and controllability, has become the definitive choice for upgrading pump and fan systems.
AKT Product Solution AKT specializes in providing drive solutions for pump and fan systems, centered on high-efficiency Brushless DC Motors (BLDC).
High-Efficiency & Energy-Saving Solution: This is the core value of BLDC motors. Compared to traditional induction or PMDC motors, our BLDC motor series (frame sizes 28mm to 130mm) maintains extremely high operating efficiency (up to 85%-90%) across a wide range of speeds and loads. This means our BLDC solution consumes less power when driving the same impeller or pump head. The energy savings are significant, especially in continuous-run applications like HVAC or circulation pumps, drastically reducing operational costs.
Wide-Range Precision Speed Control Solution: Traditional AC fans are difficult to modulate, and PMDC control is imprecise. Our BLDC motors work with intelligent BLDC drivers (which can use integrated-Hall or sensorless FOC algorithms) to achieve smooth, stepless speed regulation over a wide range (e.g., 1:100, from 100 RPM to 10,000 RPM). The driver accepts analog (0-10V), PWM, or bus signals, enabling precise closed-loop control of flow or airflow to perfectly match the demands of intelligent systems.
Long-Life & High-Reliability Solution: Pumps and fans often require continuous operation for tens of thousands of hours. Our BLDC motor’s brushless design fundamentally eliminates brush wear and sparking, allowing lifespans to easily exceed 20,000 hours. Furthermore, their operation is extremely quiet with minimal vibration, making them the best choice for silent applications like medical ventilators and high-end appliances.
Engineering & Customization Capabilities: We offer deep customization for pump and fan clients: including matching the motor’s operating point to the customer’s impeller or pump P-Q curve for optimal fluid dynamics; customizing high-protection-rated (IP65+) sealed structures for humid or dusty environments; and providing highly integrated PCBA solutions (motor + driver in-one) to simplify customer installation and wiring.
Typical Application Equipment Examples
HVAC and Ventilation Systems: Fans in large commercial HVAC and fresh air systems are a major source of building energy consumption. Our high-power BLDC motors (e.g., 86mm, 110mm series) with FOC drivers can infinitely vary the airflow based on indoor load, saving up to 50% energy compared to traditional AC fans, all while running exceptionally quietly.
Precision Dosing Pumps: In medical or chemical fields, dosing pumps require extremely high flow stability and accuracy. Our BLDC motors paired with planetary gearboxes (to increase resolution and torque) and controlled by a driver’s speed loop, provide a constant, non-pulsating rotational speed for high-precision fluid metering. For lower-cost options, hybrid stepper motors are also a common choice.
NEV Electronic Water Pumps (E-Pump): The battery and electronics in NEVs require efficient liquid cooling. Our automotive-grade BLDC motors (often 12V/24V/48V low voltage) are the core of these e-pumps. They are compact, efficient, and long-lasting. The driver can communicate with the vehicle’s VMS via CAN bus to intelligently regulate coolant flow, making them a critical thermal management component.
Summary AKT focuses on providing more efficient and intelligent pump and fan drive solutions. We don’t just supply standard motors; we can co-design based on your impeller/pump characteristics to optimize the entire system’s efficiency and NVH performance. We provide a complete system from the BLDC motor to the intelligent driver, helping you develop end-products that meet the latest energy efficiency standards.
