摘要： 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 (1) includes: a shroud (2); a motor (3) secured to and supported at the shroud (2); an axial-flow fan (4) connected to a rotation shaft part of the motor (3); and a heat shield panel (5) mounted at the rear side of the motor (3) with a gap being provided therebetween, in which the heat shield panel (5) has a spatula-shaped air guiding part (52) projecting outward in a radial direction at at least one location on an outer circumference portion; and the air guiding part (52) has a width gradually reducing toward an outer side and a fan-rotational-direction leading edge part (53) having an arc shape.
