Description
Technical field
The utility model belongs to technical field of generators, relates to a kind of reluctance generator, relates 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 made salient pole type by common silicon steel plate stacking, are wound with concentrated winding on magnetic pole of the stator, 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, make easily, and the operational efficiency height, the power factor height, starting current is little, and detent torque is big, and overload capacity is strong, all has high efficiency simultaneously in wide speed regulating range.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 by Mechanical Driven excitation when switch reluctance generator (the be called for short SRG) state, and generating is that unidirectional timesharing is uncontrollable, and the generating state electric current also is unidirectional; What the more important thing is that original switched reluctance machines SRM is converted under the switch reluctance generator SRG state output 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, manufacturing cost and operating cost 1/3～2/5 have been increased 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, excitation phase-splitting in turn by the timesharing of Electronic Control power tube phase-splitting excitation when motor rotates a circle is generated electricity, good maximum two-phase generatings as control, because the timesharing excitation has occupied the regular hour, generated output is 60% of a power of motor only, so influenced generating efficiency.
My utility model patent " power generation machine for switched reluctance motor " (patent No. 200820028231.3) applied for be rotor not under the state of excitation by the Electronic Control stator winding, energising produces rotating magnetic field and uses as motor, by producing electric energy output by excitation under the effect of Mechanical Driven revolving force, and the stator-rotator magnetic number of poles is unequal, 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.Because according to the different numbers of phases of switched reluctance machines with decide slip utmost point technology, 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.
