A power generator is provided to effective remove moisture from an inner space of the power generator by mounting a band heater on an outer circumference of a bracket. An exciter supplying an excited current to a main rotor(10) of a power generator includes a rotor(30) supported by a rotation shaft at a center portion and a stator(40) spaced apart from the rotor in a clearance between the stator and the rotor. A band heater(60) is mounted on an outer circumference of a bracket(50) fixing the stator to a case. The band heater has first and second heating members, a heat wire heating the first and second heating members, an insulator covering the heat wire, and coupling members formed on both end sides of the heating member.
