PROBLEM TO BE SOLVED: To provide an exciter capable of decreasing the magnetic reluctance and iron loss of an exciter (stator) in which a yoke is divided into a circumferential direction and a field machine (rotor) to increase magnetic flux (B), and the system machine and a synchronous machine employing the same. SOLUTION: The exciter generates a shifting magnetic field by being applied with current. The exciter has a yoke and a teeth, the yoke is divided into the circumferential direction of the exciter, the easy axis of magnetization of an electromagnetic steel sheet forming the teeth is inclined byθ1 deg (preferably, 5 deg≤¾θ1¾≤10 deg) against the radial direction of the exciter.
