Abstract
When an axial gap rotating electrical machine is assembled, stator cores are accurately positioned and a manufacturing process therefor is simplified. The axial gap rotating electrical machine comprises: a housing frame body having a first space in the cylindrical central part thereof and multiple second spaces located in the circumferential direction which have the same distances from the center; a shaft rotatably provided in the first space in the housing frame body; a core placed in each of the second spaces in the housing frame body and a coil arranged around the core; a rotor yoke fixed on the shaft, extended in the direction of the circumference thereof, and having multiple magnets arranged in circumferential positions confronting the cores; and a case having a hole for the shaft and housing the housing frame body and the rotor yoke.
