PURPOSE: A cover housing for a motor is provided to be protruded toward the center of an inner side unit, thereby reducing the interval between the bearing hub, improving the stability of the dynamic characteristic and shafting of the bearing hub, preventing the interference with a stator coil, effectively supporting the dynamic load which generates in the rotation of the motor by forming a plurality of rib in the outer side unit, and reducing the material cost. CONSTITUTION: The outer side of a cover housing (100) is comprised of the followings: an outer circumference unit (120) in which a plurality of coupling hole (121) for the bolt combination with the motor housing is formed along the columnar direction, a recess unit (130) which is formed to be depressed from the inner side of the outer circumference unit to the center; and a circular protrusion type central unit (140) which is formed in the center of the recess unit and is protruded to the outer side of the cover housing. In the recess unit, a plurality of reinforcing rib (150), which is arranged in the radial shape toward the center, is formed. |
