Introduction of Our High Speed EC Motors with Extrusion Aluminum Casing


At Suzhou Dowell Ventilation Technology Co., Ltd., we are excited to introduce our High Speed EC Motors with Extrusion Aluminum Casing. These motors are specifically designed for direct drive applications, primarily for EC axial fan impellers, offering excellent performance and energy efficiency.


Our High Speed EC Motors operate within a speed range from 600rpm to 1800rpm or higher, depending on the specific needs of your application. With precise speed control, they ensure optimal airflow, making them perfect for a variety of ventilation and cooling systems. The integrated inverter at the non-drive end (NDE) simplifies installation with a 1.5-meter cable that connects easily to the power and control circuits without the risk of damaging the inverter board.


Built to withstand challenging environments, these motors come with an IP66 protection rating, which means they are resistant to dust, water, and corrosion. This makes them highly suitable for industrial applications. The inverter board is filled with thermally conductive adhesive, which ensures effective heat management and prolongs the motor’s lifespan.


The casing of our motors is made from extrusion aluminum or die-cast aluminum, both of which are chosen for their strength, lightweight nature, and excellent thermal dissipation properties. This ensures the motor operates efficiently even in demanding environments.


Our motors cover a power range from 0.3kW to 4kW, with a rated torque range of 1.2Nm to 48Nm. This makes them versatile for use in a variety of applications, from industrial ventilation to livestock farming. They support 50/60Hz frequency power inputs and can handle input voltages ranging from 360VAC to 460VAC (three-phase) or 200VAC to 270VAC (single-phase). Additionally, we offer customized power inputs such as 115VAC single-phase or 230VAC three-phase configurations.


These High Speed EC Motors are ideal for industries requiring energy-efficient, low-noise, and durable motors, such as HVAC systems, industrial ventilation, and more.

Key Features of High Speed EC Motors with Extrusion Aluminum Casing


Lightweight Design

The extrusion aluminum casing makes the EC motor lightweight, improving installation ease and reducing overall system weight. This ensures that the motor is more efficient in various applications, from industrial ventilation to HVAC systems.


High Power Density

By using NdFeB (rare earth) magnets, our EC motors achieve high power density. This ensures that the motor performs at optimal levels while maintaining a compact design, ideal for applications requiring reliable and efficient energy consumption.


Energy-Efficient Performance

Our EC motors meet the IE5 energy efficiency standard, providing excellent energy savings and reducing operational costs. With compliance to IEC60034-30-2-2016, these motors ensure low power consumption without compromising performance, making them a great choice for eco-conscious industries.


Versatile Mounting Options

These motors offer multiple installation configurations, including slide rail, foot mount, and B14 flange mount, all of which are compatible with IEC standard frame sizes. This flexibility allows for easy integration into various systems, making our EC motors perfect for HVAC systems, industrial ventilation, and other applications.


Direct Drive for Efficiency

Our EC motors directly drive the fan impeller, eliminating the need for belts or pulleys. This direct drive design reduces mechanical losses and improves the overall efficiency of the ventilation systems, providing more reliable and consistent performance.


I/O Control Features

Equipped with I/O control capabilities, our EC motors offer start/stop, clockwise/counterclockwise rotation, and speed control signals. This makes the motor highly customizable, allowing users to adjust speed and direction according to specific application needs.


Modbus Communication Support

For advanced control and monitoring, our EC motors support Modbus communication. This feature allows easy integration with control systems, enabling remote operation, fault detection, and speed regulation, all through the Modbus protocol.


Compact and Efficient Design

The compact design of our EC motors makes them an ideal choice for use in EC axial fans, where space constraints are a concern. Despite their small size, these motors maintain high efficiency and power, making them perfect for use in energy-efficient systems.

Applications of High Speed EC Motors with Extrusion Aluminum Casing


Enhanced Cooling in Air-Cooled Condensers

High-speed EC motors are commonly used in air-cooled condensers to improve airflow over the fins. These fans pull air into the condenser, helping to dissipate heat absorbed by the refrigerant. The efficiency of these fans directly influences the overall performance of the cooling system, ensuring effective heat exchange and energy savings.


Optimizing Heat Exchanger Systems

In heat exchanger systems, achieving high airflow performance while minimizing energy consumption is essential. EC motors are ideal for this task, as they deliver superior efficiency and performance. By selecting energy-efficient fans and incorporating speed control, users can dynamically adjust the fan speed according to the cooling demand, ensuring optimal performance in varying operating conditions.


HVAC and Industrial Ventilation

In HVAC applications, High-speed EC motors are often used to drive fans in air handling units, ducts, and cooling towers. Their ability to provide precise airflow control with minimal energy consumption makes them perfect for both residential and industrial HVAC systems. They also help reduce the environmental impact by lowering energy usage without compromising comfort.


Livestock Ventilation Systems

In the agricultural sector, particularly in livestock farming, EC axial fans driven by High-speed EC motors provide efficient air circulation in barns and animal housing. Proper ventilation is crucial for animal health, growth, and productivity. These motors help maintain optimal conditions by ensuring consistent airflow while reducing power consumption, making them a sustainable solution for farms.


Air Circulation in Commercial Spaces

For warehouses, workshops, or other large commercial spaces, EC motors are used in exhaust fans to maintain air quality and temperature control. The energy-efficient design helps keep operating costs low while ensuring that the air remains fresh and comfortable for employees and customers.


Centrifugal Fans in Industrial Applications

EC centrifugal fans equipped with high-speed EC motors are widely used in industrial applications, such as dust extraction systems, fume hoods, and air filtration units. The combination of high efficiency and adjustable speed control ensures that these fans operate at optimal performance levels while minimizing energy consumption.


Booster Pumps for Enhanced Airflow

In systems requiring high-pressure airflow, such as pneumatic conveyors or ventilation systems, EC motors are employed to power booster pumps. These pumps are essential for improving airflow and pressure levels in applications where high performance and energy efficiency are critical.


Heat Exchangers and Industrial Cooling Systems

Finally, High-speed EC motors are also used in industrial heat exchangers to drive fans that maintain the correct temperature and pressure levels for efficient operation. Their precise control capabilities and energy-saving features make them a preferred choice for industries focused on reducing operational costs while maintaining high-performance standards.
