Abstract
The present invention provides a fan motor capable of achieving both an improvement in a self cooling function of the fan motor and a reduction in fan noise, and of preventing the occurrence of heat damage, problems, and the like caused by external radiation heat and by self-heating, fan noise, and deterioration in fan performance and in fan efficiency. The fan motor () includes: a shroud (); a motor () secured to and supported at the shroud (); an axial-flow fan () connected to a rotation shaft part of the motor (); and a heat shield panel () mounted at the rear side of the motor () with a gap being provided therebetween, in which the heat shield panel () has a spatula-shaped air guiding part () projecting outward in a radial direction at least one location on an outer circumference portion; and the air guiding part () has a width gradually reducing toward an outer side and a fan-rotational-direction leading edge part () having an arc shape.
