Title: Laminated core of rotating electric machine
Inventor: IIJIMA MASAKI
IPC: H02K1/02
Filed: 2002-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a laminated core of a rotating electric machine capable of suppressing the influence upon a device characteristic to the utmost while employing an adhesive bonding method.  <P>SOLUTION: The laminated core 19 of the rotating electric machine is formed by integrally laminate-bonding a plurality of steel pieces 1. Insulating layers 3 formed of insulating films are formed between opposing faces of the steel piece 1 and the adjacent steel piece 1. The steel pieces 1 are bonded with an adhesive 2 having a magnetic property that is magnetizable in a magnetic field. Since the adhesive 2 becomes a magnetic substance, magnetic flux is made to pass thereto, and the substantial lamination thickness of the core is increased compared with a laminated core in a conventional adhesive bonding method, thus improving the device characteristic and suppressing the degradation of the device characteristic associated with the use of the adhesive.  <P>COPYRIGHT: (C)2004,JPO
