Generator with multiple outputs

A generator with multiple outputs, comprising:

• an outer housing having an internal space;
• a stator fixed to an inside of the outer housing, having a hollow structure, and wound with a first coil thereonto;
• a first rotor rotatably placed inside the stator to be supported for rotation against the outer housing, having a hollow structure, and coupling a plurality of permanent magnets thereto in both circumferential and longitudinal directions thereof;
• a second rotor rotatably placed inside the first rotor to be supported in rotation against the first rotor and wound with a second coil thereonto;
• a driving part placed on an outside of the outer housing to provide a driving force so that the first rotor and the second rotor rotate in opposite directions to each other;
• and
• first and second output induction parts adapted to induce and output induced currents generated from the first coil and the second coil according to a rotation of the first rotor relative to the stator and a rotation of the second rotor relative to the first rotor to the outside of the outer housing,
• wherein the outer housing comprises:
• a housing case having a hollow cylinder shape, the housing case having both sides that are open;
• and
• first and second housing caps coupled to the both sides of the housing case to close the both sides of the housing case,
• wherein the first and second housing caps have first and second through holes defined on central portions thereof, and
• wherein the first rotor comprises:
• a first rotor case having a first side rotor shaft passing through the first through hole to be exposed to the outside of the outer housing, a connection block connected with the first side rotor shaft, and a plurality of magnet coupling bars protruding from the connection block to be spaced apart from one another in a circumferential direction of the connection block to allow the plurality of permanent magnets to be coupled thereto in longitudinal directions thereof;
• and
• a first rotor cap having a second side rotor shaft passing through the second through hole to be exposed to the outside of the outer housing and a coupling block coupled to protruding ends of the plurality of magnet coupling bars to prevent the plurality of permanent magnets from escaping from the plurality of magnet coupling bars.
