Disk type wind-mill generator

Abstract

The invention is a disc wind power generator, where a stator is composed of windings without ferromagnetic material; a permanent magnet fixed on a rotor spindle is a rotating body with the rotor spindle as axis and corresponds to permanent magnets fixed in the upper and lower casings, the opposite surfaces has the same polarity and there is a gap between them; the generating line of the rotating body is a curve or a broken line or an oblique line. Because eliminating iron core, the magnetic resistance is reduced. Because eliminating bearing, it forms air suspension between the rotor spindle and the stator, reducing no-load resisting torque, raising efficiency of motor and implementing breeze power generation; the permanent magnet whose generating line is a curve or a broken line or an oblique line makes the rotor spindle able to automatically align and reset.

Description

technical field [0001] The invention relates to the field of generators, in particular to wind power generators, in particular to a disc wind power generator. Background technique [0002] A traditional disc generator is mainly composed of a rotor, a stator, and a rotating shaft, and the rotating shaft supported by bearings rotates together with the rotor. For example: Chinese Patent No. 94222786.7, a utility model patent, discloses a "disc permanent magnet generator mechanical structure". Due to the use of stator core and winding structure, the magnetic resistance is relatively large, and the rotor shaft is supported by bearings. It is not easy to start under the state; the 94118835.3 Chinese invention patent published on September 20, 1995, which uses wave power generation, discloses a "brushless DC wave generator". Although the stator winding does not contain iron core materials, the rotor shaft is also made of bearings. Support, large starting torque. China Patent No. ...

Due to the use of stator core and winding structure, the magnetic resistance is relatively large, and the rotor shaft is supported by bearings. It is not easy to start under the state; the 94118835.3 Chinese invention patent published on September 20, 1995, which uses wave power generation, discloses a "brushless DC wave generator". Although the stator winding does not contain iron core materials, the rotor shaft is also made of bearings. support, large starting torque

China Patent No. 99243654.0 is a utility model patent for "Magnetic Levitation Permanent Magnet Wind Power Generator", which uses a magnetic levitation device to replace the bearing and improves the efficiency of the generator. However, this technology uses the traditional cylindrical permanent magnet wind power generator technology, and the no-load resistance The torque is large, and the magnetic levitation device that replaces the bearing is composed of inner and outer rings. After the rotor shaft moves or jumps, it is difficult to find and reset
