Abstract:
1. A driving motor for transmitting a rotation force to a rotor member so as to rotate the rotor member, wherein a motor main body includes: a rotating shaft for rotating the rotor member which is attached to one end in an axial direction; a rotor assembly being attached to the rotating shaft and rotating together with the rotating shaft; a stator assembly facing the rotor assembly in a radial direction of the rotating shaft and being arranged not rotating together with the rotating shaft; a control circuit-board that controls rotation of the rotating shaft as well as the rotor assembly; and a housing having a first opening which is formed in the relative vicinity of the rotor member and a second opening relatively spaced apart from the rotor member, whereas the housing extends from around of the rotating shaft to outward in a radial direction of the rotating shaft at the vicinity of one end, where it opens at the other end of the axial direction of the rotating shaft, and the housing at the other end of the axial direction of the rotating shaft is covered by a flange, thus the housing and the flange define a motor interior-space, and the housing, being made of a metal, is attached to a case in which an air duct is defined inside so that an external surface of the housing is exposed to the air duct, and at least the stator assembly is contained in the motor interior-space of the housing, wherein one end in the axial direction of the rotating shaft is protruding outwardly toward the rotor member side from the housing, and the other end in the axial direction of the rotating shaft is contained in the motor interior-space, and wherein the rotor assembly is also contained in the motor interior-space of the housing, the control circuit-board is arranged to be contained in the motor interior-space of the housing, being located in the vicinity of either one of the one end and the other end of the rotating shaft than the rotor assembly and the stator assembly in the axial direction of the rotating shaft, and a yoke is disposed to be contained in the motor interior-space of the housing, being located in the other one of either one of the one end and the other end in the axial direction of the rotating shaft.
