External rotor fans are suitable for a wide range of applications

2023-09-28

Unlike conventional motors, which have their rotors inside the wound stator, External Rotor Fans have their rotor on the outside. This allows the fan impeller to be fitted directly to the shaft of the motor, making it a complete plug-in unit. It also enables precise balancing as the hub and the impellor become one integrated unit of short axial length. This in turn leads to small efficient motors, ideal for saving space within equipment. It also increases torque inertia, which allows the fan to absorb fluctuations in load without loss of speed and without the need for high-wear gears.

External rotor fans are suitable for a wide range of applications including cooling and ventilation systems. They are especially useful in industrial applications where they can be used to provide low pressure airflow for dust removal, cooling processes and drying processes. The fans are available in both AC and DC models to meet specific application requirements.

The advantage of these fans is that they produce a large volume of air at relatively low noise levels, making them well-suited to use in machinery and machine tools where sound insulation is important. The fact that they operate at lower speeds than centrifugal fans means that they can be fitted to machines with smaller doors and can therefore be easily transported from site to site.

Axial fans have the ability to move large volumes of air at low pressure, making them ideally suited for use in machinery and machine tools where the cooling capacity of the device is more important than the pressure of the flow of air. They can also be used in ventilation systems to create a fresh air environment in factories, warehouses and workshops.

This type of fan is usually used in conjunction with heaters, welding machines and high and low temperature boxes. They are also often found in the air conditioning system of central air conditioning outdoor units, as well as being used for the ventilation of commercial freezers and cold storage rooms. They are also widely used in the ventilation of hospitals, hotels, meeting rooms and stations. In general, they can be used anywhere that needs air ventilation. We offer both single phase and three phase asynchronous AC-Outer Rotor Fan Motors. They are built with quality materials and are UL-approved in America, RHOS, CE approval in Europe and CCC safety certificate in China.

Our External rotor Fans are made in our factory with modern production lines, which include plastic injection, motor winding and die-casting processing lines. This allows us to shorten the production time of our products to 4-6 weeks, thereby significantly improving our delivery reliability. The finished products are tested for safety and performance and packaged according to the customer's requirements.
