Driving Motor
First Claim
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 relatively 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.

Abstract
Provided is a driving motor that will meet the requests of making the length of a rotating axis of the driving motor to be shorter in the axial direction, and which will also have waterproof, vibration resistance, and soundproof characteristics. In this driving motor (3); a motor interior-space (35) is formed by a housing (21) that has a first and second opening and which is formed to be cylinder shaped, and a flange (22) that blocks the second opening of this housing (21); and a stator assembly (18), a rotor assembly (20), a lower-side end section of the rotating axis (12) that has been placed lower than the flange (22) up until now, and a control circuit-board (19) are all made to be contained in this motor interior-space (35). Furthermore, a ring-shaped elastic member (45) is made to interpose between the upper-side end section of the rotating axis (12) and the first opening of the housing (21); and the lower-side end section of the rotating axis (12), the stator assembly (18), and the rotor assembly (20) are made to be fixed to the flange (22) through a mounting elastic member (59).
