PROBLEM TO BE SOLVED: To provide an axial air gap synchronous machine having a rotor structure suitable for two-rotor one-stator synchronous machine. SOLUTION: An axial air gap synchronous machine is so constructed that rotors 100 and a stator 200 are disposed facing each other with an axial gap of an output shaft 300 in between. The rotors 100 include a disk-shaped ferromagnetic back yoke 120; multiple magnets 110, disposed with an equal angular pitch in the direction of the circumference of the back yoke 120; and a paramagnetic or nonmagnetic front cover 130 bonded to the back yoke 120 so that it covers the multiple magnets 110 and is pressed against the back yoke 120. The front cover 130 is disposed such that it faces the stator 200. COPYRIGHT: (C)2007,JPO&INPIT
