Generator with closed-magnetic-path coils

A generator with closed-magnetic-path coils, comprising a casing, a base, a stator, a rotor, a transmission shaft, and a fan, wherein a magnetic conductive material is fixed to the transmission shaft, a magnet is fixed to the magnetic conductive material, and the magnetic conductive material and the magnet form the rotor;

• a magnetic conductive bracket is fixed to the casing, a coil winding or a conductor winding is fixedly installed on the magnetic conductive bracket, and the magnetic conductive bracket and the coil winding or the conductor winding form the stator;
• the transmission shaft and the casing are in rotatable connection, one end of the transmission shaft is fixed to a drive wheel for inputting power, and the other end is fixed to the fan;
• a magnetic conductive material is fixed to the casing to serve as a mechanical support of a rotating part, or the casing itself is formed by the magnetic conductive material and serves as a mechanical support machine of the rotating part;
• one pole surface of the magnet on the rotor is corresponding to a profile surface of the coil winding or the conductor winding on the stator, and the other pole surface of the magnet is fixed to the rotor magnetic conductive material, fixed to the transmission shaft, or fixed to the magnetic conductive material as a whole then fixedly installed on the transmission shaft;
• the coil winding or the conductor winding and a drive motor share the rotor;
• a prime mover drives the rotor to rotate and the magnet rotates along with the rotor, unipolar magnetic force lines of the magnet cut the coil winding or the conductor winding, the coil winding or the conductor winding is induced to generate current, an interior and an exterior of the coil winding or the conductor winding are fixedly connected through the magnetic conductive material, and magnetic force lines in a magnetic field generated by the current in the coil winding or the conductor winding concentrate in and pass through the magnetic conductive material to form a closed loop;
• and the magnetic force lines of the magnet on the rotor pass through the magnetic conductive material in the coil winding or the conductor winding, and return back into the magnet after passing through the magnetic conductive material on the casing to the magnetic conductive material on the rotor, so as to form a closed loop of the magnetic force lines of the magnet on the rotor.
