PROBLEM TO BE SOLVED: To obtain a structure which can easily and precisely secure the rotatory balance of a rotor, and efficiently radiates heat generated from a driving coil in a motor to the outside, in a motor integral-type blower.SOLUTION: A hub 119 includes a boss 114, a radiator plate 115, and a cylindrical part 118, and a blade 117 is disposed at the periphery of the hub 119. The radiator plate 115 has one face exposing to the stator coil 107 side, and the other face exposing to the axial outside. Heat generated in the stator coil 107 and a stator core 105 is absorbed to the radiator plate 115 as radiation heat, and furthermore, the heat is radiated from the radiator plate 115 to the outside. |
