Abstract
The invention discloses a kind of electromagnetic-energy engine.This electromagnetic-energy engine is not as common salient pole synchronous electric machine, be arranged in the breach between the rotor with salient pole by galvanic winding but be placed on equably in the groove of salient pole rotor pole body, between the pole body of salient pole rotor and pole shoe, have additional rotor airgap, thereby the mechanical output of output is increased.
Description
The invention belongs to the electromagnetic-energy frontier.
Common motor mainly is made up of three parts of the air gap between stator, rotor and stator and the rotor.Conductive winding all is being set on stator and rotor, and the main flux that they produce separately is all respectively by the air gap between stator and the rotor.Magnetic field in the air gap is by stator and the common resultant magnetic field that produces of rotor current.By the electromagnetic induction of this synthetic air-gap field by producing between stator and the rotor, between stator and rotor, transmit electromagnetic power, realize the mutual conversion of electric energy and mechanical energy.In transfer process, because a series of losses of motor itself, so power output is always less than input power.
Chinese Lin Andong residing in American discloses a kind of new electricity generation system-pulse electromagnetic kinetic energy engine in the WO83/01353 patent documentation.This system combines microelectric technique with electromagnetism stepping motor electricity generation system, obtain bigger power output with less power input.But because main frame is the pulse electromagnetic stepping motor, under the situation of any mechanical load torque, its rotating speed and torque are all fluctuateed, and its rotating shaft can not directly drive mechanical load or generator as power output.Moreover because pulse electromagnetic stepping motor stator coil magnetic core is subjected to the restriction of manufacturing process, its volume also is restricted accordingly.Therefore, the mechanical output and the electric energy of this system's output are all less, the output that is difficult to solve powerful mechanical energy and electric energy.
The objective of the invention is,, invent the electromagnetic-energy engine of a kind of power output greater than input power according to electric current stressed basic principle in magnetic field.
The approach that realizes above-mentioned purpose is that by stator (1), salient pole rotor (7) constitutes the electromagnetic-energy engine main part.Three-phase alternating current armature winding (3) is arranged on the stator (1), between stator (1) and salient pole rotor (7), leave air gap (9), rotor DC armature winding (8) evenly is placed in the groove of salient pole rotor (7) pole body, has additional rotor airgap (11) between the pole body of salient pole rotor (7) and rotating pole-piece (14).

The electromagnetic-energy engine main part is made of stator [1], salient pole (two utmost points) formula rotor [7].Three-phase alternating current armature winding [3] is arranged on the stator [1], between stator [1] and salient pole rotor [7] air gap [9] is arranged, the size of this air gap and same volume, identical with the size of gaps of rotating speed threephase asynchronous machine generally adopt δ

The operation principle of this electromagnetic-energy engine is: after passing to electric current for every utmost point DC armature winding [8], the main flux [5] that is produced by it self forms the closed-loop path by rotor airgap [11] every extremely the going up of salient pole rotor [7], not by the air gap between stator and rotor [9], the main flux [16] that is produced by stator three-phase alternating current armature winding [3] is not had longitudinal axis demagnetizing effect, have only less transverse axis demagnetizing effect.The AC and DC armature winding of stator, rotor is only gone up at salient pole rotor [7] and is formed the resultant magnetic field.Magnetic field by the air gap between the stator and rotor [9] is different with general motor, and it is not by the common resultant magnetic field that produces of stator and rotor winding, but absorbs the reactive current magnetization from electrical network.With regard to the electric current of stator winding, because total gas length (gas length between stator and rotor [9] adds rotor airgap [11] length) is equivalent to the asynchronous motor of the very big no-load running of reactive current than same volume, much bigger with the general motor of rotating speed.According to the principle of general motor by the transmission of the air gap between stator and rotor electromagnetic power, the electromagnetic power that rotor produces is not to import into from stator terminal, so power factor COS φ is very low, and active current I
