Abstract

PURPOSE: To prevent the charging of static electricity on plastic impeller by coating a conductive paint continuously on the surface and boss portion of the plastic impeller and a part of rotor shaft in contact with the impeller boss portion.
CONSTITUTION: In the motor fan 4 the rotor shaft 5 of which is fitted with the impeller boss 6 of the plastic impeller 3 made of a glass fiber-reinforced plastic, for example, the conductive paint 7 is coated on the whole surface of the impeller 3, the impeller boss 6, and a part of the rotor shaft 5 in contact with the boss. Thus, the static electrocity generated on the surface of the impeller 3 makes up of an electric circuit to the earthed portion of the wind channel of a radiator body, for example, provided with the impeller boss 6, the rotor shaft 5, the motor, and the motor fan, permitting the release of the static electricity generated on the surface of the impeller 3 by friction with atmospheric suspended dust upon the rotation of the impeller 3 all the time.
