Zusammenfassung: | PURPOSE: To provide a stator core manufacturable by a smaller number of parts and having a high radiation efficiency, and a motor having simple construction and a smaller volume to output ratio. CONSTITUTION: This is a stator core provided with a plurality of boards 111, made of high-permeability material having outside outlines 11a in shapes having equal distances from a center O1 of an inside outline 12a of a stator. The boards 111 are turned/piled up and laminated. Turning and piling-up may be performed by every board sheet, or by every several sheets. Since boards made of high- permeability material are turned and piled up, the outside outline of the core is fitted with fins.
본 발명은, 적은 부품점수로 방열효율이 높은 고정자코어 및 단순한 구조로 출력당의 체적이 작은 전동기를 제공하는 것을 과제로한 것이며, 그 해결수단으로서, 고정자내형(12a)의 중심(01)에 대해서 비등거리형상의 외형(111a)을 간진 복수의 고투자율재료제의 시트(111)를 구비하고, 상기 복수의 시트(111)가, 돌려가면서 쌓기로 적층되어 있는 고정자코어와, 이 고정자코어의 상기 돌려가면서 쌓기는 1시트마다로도되고 복수시트마다로도되며, 고투자율재료제의 시트가 돌려가면서 쌓기되므로, 코어의 외형은 핀부착으로되는 것을 특징으로 한 것이다. |
