Description

Magnetic energy developing machine

Magnetic energy is the active energy of perpetuity, is a kind of new forms of energy that can be developed application.

Magnetic energy motor of the present invention, magnetic-energy generator and magnetic energy unit thereof are that magnetic energy is directly changed into mechanical energy, directly changes electric energy or directly change electric energy into and mechanical energy is exported the machine of application simultaneously into.

The magnetic energy developing application mechanism is: when magnetic-energy machine adds certain field power supply, just produce magnetic energy in the air gap between stator and rotor, when changing magnetic energy into mechanical energy output, make simultaneous back electromotive force power acting weaken the corresponding minimizing of input electric energy of balance with it; When changing magnetic energy into electric energy output, simultaneous anti-electromagnetic torque is weakened, the corresponding minimizing of input mechanical energy of balance with it, magnetic energy promptly is developed application.

The magnetic energy developing rate of magnetic-energy machine:

K _p=(magnetic energy output)/(energy input-loss)＞1

Magnetic energy developing machine of the present invention, simple and reliable for structure, cost is not high, and operation is convenient.When making generator operation, not only replace fuel and all types of generators such as coal, oil, and high pressure long distance power transmission net has not existed.Environmental pollution and balance of nature make moderate progress, and the technology and society productivity that advances science advances.

Magnetic energy in the field of magnetic, is not study one of clear problem as yet.So far, magnetic energy only as " media " in power conversion (electric energy-mechanical energy) process, is considered as a kind of passive can being applied in motor.

1。Magnetic energy motor of the present invention is directly to change magnetic energy into machine that mechanical energy output is used.Its electromagnetic structure principle is shown in accompanying drawing (1).Stator by main pole 4., pay magnetic pole 2. with yoke 7. and corresponding excitation winding 5. and 3. form, the magnetic pole of the stator iron core is stamped to form by electric steel plate, 8. the casing that is anchored on aluminum with the extruding of each pole core of stator with the nonmagnetic substance chock between the adjacent pole core 1. in, magnetic pole of the stator is split into and is three times in the rotor magnetic pole number, air gap under the magnetic pole (11) skewness, pay fixedly magnetic bridge of magnetic pole utmost point facies palmaris 2., magnetic bridge laminates (13) by the steel disc warp-wise of certain insulation thickness, and nexine has certain thickness nonmagnetic substance dividing plate (12) to form.The similar common DC motor rotor of rotor electromagnetic structure principle (comprising commutator and brush).

Its operation principle: 6. the rotor winding of energising produces rotor field Ha, because commutation, rotor field time to time change not under certain air gap, it does not produce induced electromotive force to the stator excitation winding, the electromotive force that the rotor field produces in the rotor winding that is rotating, owing to the electromagnetic structure symmetry on brush both sides is cancelled out each other, so rotor input electromagnetic field is not had influence yet.The stator excitation winding can with rotor windings in series and in parallel, also can power separately.
