Abstract
Official abstract text for this publication.
Recesses and projections that extend in an axial direction are formed on an outer-circumferential surface of a molded resin body. The recesses are provided on portions where are extended outward from teeth having the winding and are on the outer circumferential surface. In addition, further recesses and projections that extend in a radial direction are formed on an axial-direction end surface of the molded resin body. The further recesses are provided on portions of the axial-direction end surface that are aligned in the axial direction with the winding.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor comprising: a stator that includes a stator core formed of a substantially ring-like yoke and teeth extending in a radial direction from an inner circumference-side of the yoke, and a winding wound around the teeth via an insulator, the stator being formed of a molded resin body encapsulating the stator core, the insulator, and the winding; and a rotor including a rotor core, a motor rotating shaft inserted through a center of the rotor core and a permanent magnet inserted to the rotor core in an axial direction, the rotor core being rotatably held in the inner circumference-side of the stator via an air gap, wherein recesses and projections that extend in the axial direction are alternately formed on an outer-circumferential surface of the molded resin body, each of the recesses being provided on a portion that is extended outward from the teeth wound with the winding and is on the outer-circumferential surface. 2. The motor according to claim 1 , wherein recesses and projections that extend in the radial direction are alternately formed on an axial-direction end surface of the molded resin body, each of the recesses being provided in a portion of the axial-direction end surface that is aligned in the axial direction with the winding. 3. The motor according to claim 2 , wherein the molded resin body includes a resin material having a heat conductivity of at least 1.4 W/m·K. 4. The motor according to claim 1 , wherein the molded resin body includes a resin material having a heat conductivity of at least 1.4 W/m·K.
