Product Description

Axial Exhaust Fan External Rotor Motor Fan
Unlike conventional motors whose rotors are on the inside of a wound stator, external rotor motors have their rotor on the outside. This presents unique advantages to the fan manufacturer and user as detailed below:

An extremely compact, therefore space saving unit, is produced by utilising the external rotor component as the hub of a fan impeller.
Precision balancing is assured as the hub and impeller becomes one integrated unit of short axial length.
Heat is very effectively removed in the airstream, assisted by the fan impeller that acts as a rotating heat sink of appreciable surface area.
Speed control is then possible by low cost voltage variation because the extra heat generated in the rotor under speed control is lost directly into the airstream.
Air filters can be 'saved' when clean but 'air flow compensated' when dirty by the tendency of centrifugal fans to speed-up as flow resistance increases. The increase in speed is more pronounced when using external rotor motors.
In general, the external rotor principle leads to small efficient motors, ideal for saving space within equipment.

EXTERNAL ROTOR FANS

Fans housing stator and windings inside the rotor are compact, well-balanced, with widely adjustable rotation speed and good motor cooling. Built with insulation system (Class F) and integrated thermal protection. Axial fans are characterised by a series of unique properties of being quiet, robust and thermal-shielding. Useful in all those situations in a system with low pressure drop (therefore not very high resistance), the axial fans guarantee a large airflow rate.

The external rotor axial flow fan has the characteristics of compact structure, convenient installation, reliable operation, low noise, energy saving and high efficiency. The products are widely used in hotels, restaurants, industrial and mining enterprises, office buildings, theaters and other building facilities, as ancillary equipment for freezers and cold storage or for ventilation and heat dissipation. (For example, it is matched with refrigeration equipment or facilities such as supermarket freezers, ice machines, air coolers, chillers, condensing units, etc., and used with dehumidifiers, evaporators, side wall fans, fire fans, central air-conditioning fans and other equipment).

The outer rotor axial flow fan is composed of fan blades, outer rotor motor, net cover, lead wire and other parts. The structure of the fan is calculated by structural finite element, and the strength check, modal analysis, harmonic response analysis and other methods are carried out to ensure that our products have the advantages of stable and reliable structure, high safety factor, small vibration, and strong anti-interference ability! According to customer requirements, Thermal protectors, junction boxes and other components can be installed, or different installation methods such as cylinder type and box type can be selected. The blades are designed according to the principles of aerodynamics, acoustic principles and acoustic performance requirements. They are twisted according to certain rules from the tip to the root. The material is made of high-quality steel or plastic. After dynamic balance verification, it has good starting performance, stable operation and low noise.
