Abstract
A rotary electric machine member manufacturing method includes: a step of providing a motor core by stacking a plurality of electromagnetic steel sheets; and a step of welding the motor core by keyhole welding while pressurizing the motor core in a stacking direction with a welding pressure lower than that at which the thickness of the motor core in the stacking direction levels off. The thickness is a length of the motor core between a first end of the motor core and a second end of the motor core.
