Description

Generator such as magnetic resistance such as extremely two section rotor such as two grades
Technical field
The invention belongs to technical field of generators, relate to a kind of reluctance generator, relate in particular to a kind of two extremely two section rotor magnetic resistance generators that wait.
Background technology
Existing switched reluctance machines (SRM) is the motor of biconvex utmost point field structure, and its stator, rotor are processed salient pole type by common silicon steel plate stacking, on magnetic pole of the stator, are wound with concentrated winding, does not also have permanent magnet and rotor has both had winding; This motor can be divided into single-phase, two-phase, three-phase, four phase and heterogeneous switched reluctance machines by the number of phases, and again with three-phase 6/4 electrode structure, 8/6 electrode structure is in the majority mutually with four for 12/8 electrode structure; The advantage of switched reluctance machines is: simple in structure, to make easily, and operational efficiency is high, and power factor is high, and starting current is little, and detent torque is big, and overload capacity is strong, in wide speed regulating range, all has high efficiency simultaneously.Because of its rotor does not have the coil winding, thus increased the complexity of power generation machine for switched reluctance motor, stator winding be excitation winding be again the generating winding; When giving each phase winding energising successively; Motor just can produce electromagnetic torque, and motor is rotated continuously, and electric current is unidirectional when electric motor state.Yet the switched reluctance machines of prior art (SRM) is unidirectional controlled timesharing property by Mechanical Driven excitation when switch reluctance generator (the be called for short SRG) state, and generating is that unidirectional timesharing property is uncontrollable, and the generating state electric current also is unidirectional; What the more important thing is that original switched reluctance machines SRM converts under the switch reluctance generator SRG state output into is direct current energy rather than AC energy.
Because it is that the rotor magnetic pole is unequal that there is the difference utmost point in switched reluctance machines biconvex utmost point field structure; The stator magnet number of poles is greater than the rotor magnetic pole number; And also need the exciting current of switch controlled stator winding and control time of its excitation pilot angle at generating state, increased manufacturing cost and operating cost 1/3~2/5 like this, and excitation mode is the phase-splitting mode of excitation stage by stage; That is to say switched reluctance machines reversible state as generator operation in its control more complicated;, motor, generates electricity like good maximum two-phases of control, when rotating a circle because the timesharing excitation has occupied the regular hour through the generating of excitation phase-splitting in turn of Electronic Control power tube phase-splitting excitation timesharing property; Generated output is merely 60% of power of motor, so influenced generating efficiency.
My patent of invention " power generation machine for switched reluctance motor " (application number 200810017433.2) of having applied for be rotor not the state of excitation pass through the Electronic Control stator winding down; Energising produces rotating magnetic field and uses as motor; Effect by the Mechanical Driven revolving force produces electric energy output through excitation down, and the stator-rotator magnetic number of poles is unequal, and magnetic pole of the stator is greater than the rotor magnetic pole number; Can become by different number of phases different poles arrays; Belong to the phase-splitting generation technology, rotor can only be that the electric plus pole rotor that has winding is formed, and can not adopt permanent magnetism magnetic pole.Since according to the different numbers of phases of switched reluctance machines with decide extremely technology of slip, electric energy that sends and existing using electricity system are incompatible, can only change into direct current through rectifier could use, and the control technology more complicated, the manufacturing cost height.
My patent of invention " single-phase reluctance generator " (application number 200810018034.8) volume applied for is little, in light weight, owing to adopted extremely technology such as rotor, need not use Electronic Control, can not dual-use so can only make single-phase alternator.But this generator stator-rotator is salient pole, and rotor can adopt permanent magnetism magnetic pole, and rotor magnetic pole can adopt the excitatory mould assembly of electric field pole, Permanent Magnet and Electric, pawl utmost point mixed type etc. of band field winding; Use very flexible; And can satisfy the needs of different capacity, different voltage, different frequency, and power output is big, and the output voltage sinusoidal waveform is good; Little through the pulsation of rectification output dc voltage, effective when miniature small-power, multipole number, high speed operation.But at middle power, few number of poles, effect is just so perfect when operating in low speed; Especially after having adopted rotor etc. extremely technology improving power output; Rotors etc. the extremely magnetic pole of technology are equivalent to rotor N, S, N, S magnetic circuit at static magnetic pole closure state; So it is big especially to form stiction, the generating resistance of start is big, the low speed power consumption is big, the low speed noise is big, the high speed noise is little, low speed vibration is big, vibration at high speed is little thereby cause.Find through test how much relevant the size of the amplitude noise of its vibration and number of poles be, number of poles amplitude less is big more, and noise is big more; The frequency of vibration is relevant with rotating speed, and rotating speed short arc more is high more, and noise is big more.

The present invention compared with prior art has the following advantages:
1, because the present invention breaks the normal procedure, make switched reluctance machines by the difference utmost point (magnetic pole of the stator N S>rotor magnetic pole N r) utmost point (N such as become S=N r); Installed permanent magnetism magnetic pole or electric excitation pole on the rotor additional, all magnetic pole of the stator windings all are in generating state simultaneously, and make all pole regions of stator all obtain utilizing; All windings of stator winding are all utilized simultaneously; Therefore make generated output density to be multiplied according to the power composition principle, the performance of generator and efficient have also obtained effective raising, have reduced the operation temperature rise simultaneously.
2, the present invention utilizes the series-parallel dynamic combined of winding; Make output voltage regulate more convenient and can improve the utilance of winding: regulate different rotating speed and can obtain different frequency different voltages with different; Make generator under generating state, save stator armature winding electronic-controlled installation, and have only the adjustable DC power supply excitation unit of rotor, do not have switch power consumption (not needing the control of armature electronic switching tube); Thereby reduced equipment cost 1/3~2/5, improved the reliability of equipment; Simultaneously, make it not have the switch intermittent phase, solved the stator winding inductance in the not high influence of generating state rectification afterflow efficient.
3, because the present invention will common rotor be arranged to the form of internal rotor and external rotor, therefore when armature winding placed external rotor to need slip ring to supply power, the internal stator excitation pole did not then need slip ring; When excitation pole places external rotor, only be applicable to magnet limbs, and external rotor needs slip ring; When adopting the magneto external rotor, then do not need slip ring.
4, because the electric energy of the present invention output is an AC energy, so its output need not be installed inverter when using.If the present invention adopts direct current output, then can adopt phase-splitting polarity winding rectifier, its effect is better than conventional products effect, no matter to generator or external electrical rectifier, inverter, all can reduce the wastage, and reduces heating.
