DYNAMOELECTRIC MACHINE AND MANUFACTURING METHOD OF DYNAMOELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a dynamoelectric machine and its manufacturing method which enable the reduction of the number of components, the cost reduction and the reduction of assembly man-hours while insulation properties are secured. SOLUTION: A core insulator 30 which is attached to a laminated core 14 has a cylindrical part 31 fixed to a rotary shaft 14 and tooth cover elements 32 which are extended from the cylindrical part 31 radially and with same angular intervals so as to cover one side surface of the laminated core 15. Coil bobbin segments 33 are extended from the respective teeth cover elements 32 so as to cover inside surfaces of the respective slots 15b of the laminated core 15. The tip parts 33a of the coil bobbin segments 33 are made to protrude from the other side surface of the laminated core 15 when the core insulator 30 is attached to the laminated core 15.
