COMPACTED MAGNETIC CORE, PRODUCTION METHOD OF THE SAME, AND MOTOR FOR ELECTRIC VEHICLE |
摘要 |
A manufacturing method of a magnetic core includes a first step of applying a treatment liquid for forming an insulating film to iron powder; a second step of heat-treating the iron powder to which the treatment liquid has been applied, at a temperature higher than 350 degrees; a third step of compacting the heat-treated iron powder to form a magnetic core; and a forth step of heat-treating the magnetic core at a temperature ranging from 600 degrees to 800 degrees.
