Abstract

A manufacturing apparatus and a manufacturing method for a laminated core which enable low-cost, short-time, and uniform thermobonding manufacture of a laminated core comprising a thermobonding type electromagnetic steel plate. A manufacturing apparatus for a laminated core having an induction coil (2) which inductively heats a work (1) comprising a laminate of electromagnetic steel plates with thermobonding insulation film by excitation in its lamination direction and a yoke (5) which presses both ends of the work in the lamination direction with first and second yoke members (5A, 5B) movable by mutual uninterference and forms a magnetic closed circuit upon pressing. A manufacturing method for a laminated core with the excitation frequency of the induction coil adjusted to 10-1000Hz, and the pressing pressure of the yoke to 0.1MPa or more for the thermowelding of the work laminated steel plate with the manufacturing apparatus.
