Abstract
Official abstract text for this publication.
A motor includes a motor housing, a motor body, and a damping member. The motor body includes a drive shaft. The motor body is housed in the motor housing. The damping member is disposed on an outer surface of the motor housing. The damping member includes a damping layer and a constraining layer. The damping layer is made of an organic polymeric material, and bonded to the outer surface of the motor housing. The constraining layer is made of at least one of a resin mixed with an inorganic compound and an elastomer mixed with an inorganic compound. The constraining layer is disposed on the damping layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A motor comprising: a motor body including a drive shaft; a motor housing in which the motor body is housed; and a damping member disposed on an outer surface of the motor housing, wherein the damping member includes a damping layer and a constraining layer, the damping layer being made of an organic polymeric material, the damping layer being bonded to the outer surface of the motor housing, the constraining layer being made of at least one of a resin mixed with an inorganic compound and an elastomer mixed with an inorganic compound, and the constraining layer being disposed on the damping layer. 2. The motor according to claim 1 , wherein the resin is polyvinyl chloride. 3. The motor according to claim 1 , wherein the inorganic compound contains barium sulfate. 4. The motor according to claim 1 , wherein a thermal conductivity of the constraining layer is 0.5 W/mK or higher. 5. The motor according to claim 1 , wherein a specific gravity of the constraining layer is within a range from 2.0 to 2.5. 6. The motor according to claim 1 , wherein the motor housing has a cylindrical portion and a bottom portion that closes a first axial end of the cylindrical portion; the damping member has an opening located at a center portion of the damping member; and the damping member is disposed on the bottom portion, at a position at which the opening is aligned with a first axial end of the drive shaft.
