Thin strip component, method for manufacturing same, and motor using thin strip component

Abstract

A method for manufacturing a thin strip component, including a processing step of processing an amorphous thin strip member into a dimension shape larger than a target shape, and a heat treating step of heat treating and contracting the amorphous thin strip member processed in the processing step to form the amorphous thin strip member into a thin strip component of the target shape. A thin strip component which is a magnetic laminate in which a plurality of plate-shaped thin strip component members of the same shape are laminated, and has a recess over an entire side surface of the magnetic laminate is used. A motor including the thin strip component, a plurality of coils disposed on the thin strip component, and a rotor disposed between the plurality of coils is used.

         1 . A method for manufacturing a thin strip component, comprising:
 a processing step of processing an amorphous thin strip member into a dimension shape larger than a target shape; and   a heat treating step of heat treating and contracting the amorphous thin strip member processed in the processing step to form the amorphous thin strip member into a thin strip component member of the target shape.   
     
     
         2 . The method for manufacturing a thin strip component of  claim 1 , further comprising:
 a laminating step of laminating a plurality of the thin strip component members after the heat treating step.   
     
     
         3 . A method for manufacturing a thin strip component of  claim 1 , comprising:
 a processing step of processing an amorphous thin strip into a dimension shape larger than a target shape;   a laminating step of laminating the amorphous thin strips processed in the processing step; and   a heat treating step of heat treating and contracting a laminate of the amorphous thin strips after the laminating step to form the amorphous thin strips into a laminated thin strip component members of the target shape.   
     
     
         4 . The method for manufacturing a thin strip component of  claim 3 ,
 wherein, in the heat treating step, the heat treatment is performed while pressing the laminated amorphous thin strip in a lamination direction.   
     
     
         5 . The method for manufacturing a thin strip component of  claim 3 ,
 wherein, in the heat treating step, the laminated thin strip component members are bonded to each other.   
     
     
         6 . The method for manufacturing a thin strip component of  claim 3 ,
 wherein, in the heat treating step, a side surface of the laminated thin strip component members is recessed.   
     
     
         7 . The method for manufacturing a thin strip component of  claim 1 ,
 wherein the amorphous thin strip member having a dimension larger than the target shape is larger than 0% of the target shape and 0.6% or less than the target shape.   
     
     
         8 . The method for manufacturing a thin strip component of  claim 1 ,
 wherein the processing of the amorphous thin strip into the dimension shape larger than the target shape further includes the dimension shape depending on a location of the amorphous thin strip member.   
     
     
         9 . The method for manufacturing a thin strip component of  claim 1 ,
 wherein the processing of the amorphous thin strip into the dimension shape larger than the target shape further includes the dimension shape depending on a condition of the heat treating step.   
     
     
         10 . The method for manufacturing a thin strip component of  claim 9 ,
 wherein the amorphous thin strip member having a dimension larger than the target shape is increased in dimension as a temperature in the heat treating step is higher or a time in the heat treating step is longer.
