Title: METHOD FOR MANUFACTURING MEMBER FOR ROTARY ELECTRIC MACHINE
Abstract:
Provided is a method for manufacturing a member for a rotary electric machine, the method comprising: a step for laminating a plurality of electromagnetic steel plates to form a motor core; and a step for welding the motor core by keyhole welding while pressurizing the motor core in the lamination direction using a pressurizing force less than the pressurizing force at which the lamination thickness in the lamination direction, i.e., the length from one end of the motor core to the other end, is saturated.
