Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2016005383
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve rigidity in a circumferential direction by surely bringing an inner diameter side into contact while suppressing a variation in a contact state of a contact surface included in a connection core in a conventional structure in a rotary electric machine including a stator that is formed by folding the connection core in an annular manner, the connection core being formed by stacking linear connection core blanks.SOLUTION: A rotary electric machine includes the stator that is formed by folding the connection core in the annular manner, the connection core being formed by stacking the linear connection core blanks. When folding a connection core 3CS in the annular manner, in mating surfaces 3SS1, 3SS2, 3SE1 and 3SE2 of the connection core 3CS, the inner diameter side mutually opposite mating surfaces are brought into contact over a radial full length by clearance parts 3SSN and 3SEN which are provided at an outer diameter side.
