Description
The present invention relates to a kind of two-in-one dynamo-electric machine that rationally is assembled into one by transformer and synchronous motor.
According to existing technical data, known motor can change into mechanical energy with electric energy; Generator can convert mechanical energy to electric energy, but the two all can not realize the inverse conversion of energy.
Propose a kind of two-in-one dynamo-electric machine that can realize electric energy and mechanical energy inverse conversion but the objective of the invention is to design, in power output with motor and efficient, can induce electric energy again with input power myopia.
Two-in-one dynamo-electric machine stator of the present invention is made up of the synchronous motor stator, and the former auxiliary winding of stator is made up of the former auxiliary winding of transformer, and rotor is made up of generator or synchronous electric motor rotor.Therefore, these facility have with the power output of power synchronous motor and efficient, simultaneously induce electric energy with input power myopia value as generator or transformer again, as accompanying drawing.
Accompanying drawing is represented: the profile of two-in-one dynamo-electric machine of the present invention (three-phase and quadrupole).
1-stator core, 2-rotor, 3-rotor winding, 4-stator primary winding, 5-stator auxiliary winding, 6-layer insulation, 7-slot liner, 8-slot wedge, 9-rotating shaft, 10-rotor bar, 11-rotor magnetic pole insulation, 12-rotor magnetic pole
The present invention is achieved in that transformer and synchronous motor is united two into one, and lays a phase-wound rotor in the middle of the former auxiliary winding of transformer.Just three-phase synchronous motor is designed routinely, be close to winding-auxiliary winding (5) that primary winding (4) inboard embeds shape and the identical required voltage of primary winding (4) in the every phase winding groove of stator, transformer auxiliary winding just is as figure.
Two-in-one dynamo-electric machine stator primary winding (4) is connected on the three-phase alternating-current supply, just added an alternating voltage at the two ends of the every phase primary winding of stator, just have alternating current to pass through in the every phase primary winding of stator, thereby stator core (1) is magnetized the generation alternating flux.The alternating flux that is produced not only passes stator primary winding (4); Also pass stator auxiliary winding (5), thereby in the former and deputy winding of stator (4,5), produced the induced electromotive force of alternation respectively.Because the existence of the induced electromotive force of alternation is arranged in the stator auxiliary winding (5), formed a new power supply, so just there is alternating voltage at the two ends of stator auxiliary winding (5), thereby when the circuit in the stator auxiliary winding (5) is closed circuit, pass through with regard to the induced current that alternation is arranged in the circuit.According to the law of electromagnetic induction and Lenz's law, the middle sense of current of the direction of induced current and stator primary winding (4) is opposite in the stator auxiliary winding (5).Therefore, the magnetic flux that is produced by induced current in the stator auxiliary winding (5) always will be resisted the magnetic flux in the stator primary winding (4), in order to guarantee the operate as normal of two-in-one dynamo-electric machine, electric current in the stator primary winding (4) is increased, and the electric current that it is produced in the corresponding magnetic flux counteracting stator auxiliary winding (5) increases.That is to say that the size of electric current is controlled by the induced current in stator auxiliary winding (5) loop in the two-in-one dynamo-electric machine stator primary winding (4).Therefore, in the electric energy loss of not considering two-in-one dynamo-electric machine inside; Air gap between the stator and rotor is to the resistance (being magnetic resistance) of magnetic flux, and then the intake of two-in-one dynamo-electric machine equals its output energy near-sightedly, that is:
When being the pure inductance circuit in stator auxiliary winding (5) loop (inductance element is arranged), 90 ° of phase angles of induced current lagging voltage.When the electric current in the stator primary winding (4) strengthens, then increase by the magnetic flux in the stator auxiliary winding (5), learn by Lenz's law, the magnetic direction of induced current is to make by the magnetic flux in the stator auxiliary winding (5) to reduce in the stator auxiliary winding (5), and it is opposite with the magnetic direction of stator primary winding (4) lining electric current, electric current in the stator primary winding (4) does not really consume in the loop, but be delivered in stator auxiliary winding (5) loop (comprising inductance element) by the coupling in magnetic field, store with the form of magnetic energy.When the current decay of stator primary winding (4) lining, magnetic flux by stator auxiliary winding (5) lining reduces, learn by Lenz's law, the magnetic direction of induced current should make the magnetic flux by stator auxiliary winding (5) increase in the stator auxiliary winding (5), and it is identical with the magnetic direction of stator primary winding (4) lining electric current, inductance element disappearance magnetic field in stator auxiliary winding (5) loop, also give new power supply with energy stored---auxiliary winding (5).In the whole cycle, the inductance element in stator auxiliary winding (5) loop only inhale, discharge can and consumed power not.Therefore, two-in-one dynamo-electric machine inside, the magnetic flux in one-period can not reduce.After two-in-one dynamo-electric machine stator three-phase primary winding (4) is connected with three-phase alternating-current supply, in the inner generation of two-in-one dynamo-electric machine rotating magnetic field, and with n
1The speed rotation.(number of poles of stator and rotor equates because of rotor (2) has the fixed magnetic pole of installation, the middle and small motor rotor can adopt brushless reaction equation or magneto, large and middle size motor rotor magnetic pole coil is given excitation, and mouse cage sliver and end ring be housed), the N utmost point of stator rotating magnetic field attracts the S utmost point of rotor (2) fixed magnetic pole like this, the S utmost point of stator rotating magnetic field attracts the N utmost point of rotor (2) fixed magnetic pole, thereby drives rotor (2) with synchronizing speed n
1And turn round.Therefore, two-in-one dynamo-electric machine has the dual power output of transformer and synchronous motor, that is to say, when external power is imported this machine with certain electric energy, when transformer is inducing myopia ground electric energy (it is identical that the transformer identical with input power compared its efficient), convert electric energy to mechanical energy (it is identical that the synchronous motor identical with input power compared its efficient) as figure as synchronous motor again.
