In a motor that is molded with resin in part or as a whole, thermal expansion caused by temperature rise due to reduction in size and increase in output causes application of stress equal to or greater than fracture stress to the resin, thus generating cracks.;Therefore, according to the invention, in a resin-molded rotating machine, a part or the whole of a gap between plural mold resins molded in different places from each other is made of a material with a higher thermal conductivity and a lower Young's modulus than the mold resins, and these mold resins are bonded together mechanically or with an adhesive material, or are fastened by both these methods. |
