Product Description

Product Description

Ywf Series Externa Rotor Axial Flow Fan Type 2650rpm
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.
