Abstract

PURPOSE: To contrive miniaturized lightweight structure of a sirocco fan in such a way that a vane retaining plate is made into multipolar magnet construction, and a motor part is formed by arranging an induction coil which is brought near to its periphery.
CONSTITUTION: This sirocco fan is structured the fringe of the members of the vane portions 3 to be multipolar magnet mechanism, at the same time, allocation of an induction coil 1 brought near to it is made to be a motor part. And, when said induction coil 1 is excited by alternating current, movable magnetic field is generated, the vane portions 3 turn to send the blast. In that event, because the motor part which gives torque T is positioned around the periphery of the vane portions, even if the radius of the vane portions is changed, it will be all right with a constant torque. And, in case where there is a need of changing the rotation, by reason of using the multipolar magnet, it will take a high frequency induction modality, such as a stepping motor, it serves for the possibility of variability in wide range, in addition, for offering smooth rotation in the retention of larger radius.
