Abstract
An inductor-type synchronous machine having an axial gap structure, which has a shaft portion at the center thereof, the machine includes: a field-side stator which has a yoke made of a magnetic material and a field body protruding from the yoke in an axial direction of the shaft portion to form an N pole and an S pole in a radial direction; a rotor which has N pole inductors disposed so as to be opposed to the N pole formed by the field body and S pole inductors disposed so as to be opposed to the S pole formed by the field body; and an armature-side stator in which an armature coil is disposed so as to be opposed to the N pole inductors and the S pole inductors.
