Abstract
Official abstract text for this publication.
A manufacture method that includes positioning the permanent magnet body of which a surface is coated with a coating film for deterioration prevention, a scheduled cleavage portion of the permanent magnet body being located between two fulcrums, which are edge portions of a die, supporting the permanent magnet body, and cleaving the permanent magnet body into a cleaved magnet body and the magnet piece by pressing the scheduled cleavage portion of the permanent magnet body is provided. The manufacture method also includes cutting the coating-film between the cleaved magnet body and the magnet piece by pressing an end portion of the cleaved magnet piece from a pressing side of the scheduled cleavage portion, the end portion being on a side opposite to a cleavage surface side.
First claim
Opening claim text (preview).
1 . A manufacture method of manufacturing a magnet piece constituting a magnet body for a field pole disposed on a rotating machine by cleaving a permanent magnet body, comprising: positioning the permanent magnet body of which a surface is coated with a coating film for deterioration prevention, a scheduled cleavage portion of the permanent magnet body being located between two fulcrums supporting the permanent magnet body; cleaving the permanent magnet body into a cleaved magnet body and the magnet piece by pressing the scheduled cleavage portion of the permanent magnet body; and cutting the coating-film between the cleaved magnet body and the magnet piece by pressing an end portion of the cleaved magnet piece from a pressing side of the scheduled cleavage portion, the end portion being on a side opposite to a cleavage surface side. 2 . The manufacture method according to claim 1 , wherein the cutting the coating film is performed by pressing the end portion of the magnet piece on the side opposite to the cleavage surface side by an elastic body. 3 . The manufacture method according to claim 1 , wherein the cutting the coating film is performed by pressing the end portion of the magnet piece on the side opposite to the cleavage surface side by an air jet. 4 . A manufacturing device for manufacturing a magnet piece constituting a magnet body for a field pole disposed on a rotating electric machine by cleaving a permanent magnet body, comprising: a support portion supporting the permanent magnet body of which a surface is coated with a coating film for deterioration prevention on two fulcrums on both sides of a scheduled cleavage portion of the permanent magnet body; cleaving unit configured to cleave the magnet body into a cleaved magnet body and the magnet piece by pressing the scheduled cleavage portion of the permanent magnet body between the both fulcrums; and coating-film cutting unit configured to cut the coating-film between the cleaved magnet body and the magnet piece by pressing an end portion of the cleaved magnet piece from a pressing side of the scheduled cleavage portion, the end portion being on a side opposite to a cleavage surface side. 5 . The manufacturing device according to claim 4 , wherein the coating-film cutting unit is performed by pressing an end portion of the magnet piece on a side opposite to the cleavage surface side by an elastic body. 6 . The manufacturing device according to claim 4 , wherein the coating-film cutting unit is performed by pressing an end portion of the magnet piece on a side opposite to the cleavage surface side by an air jet.
