Description
One, technical field
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention belongs to special power generator.
Two, technical background
The stator of switched reluctance machines and double salient-pole electric machine and rotor are salient-pole structure, all belong to variable reluctance motor, have simple in structure, the advantage that low price and reliability are high.Switched reluctance machines is done generator when work, needs position transducer, and needs that the source power converter carries out excitation control and power is exported, and has increased the cost and the complexity of system, has reduced the reliability of system.Electric excitation biconvex electrode electric machine (patent No.: ZL 99114250.0) does not need rotor-position sensor and power inverter, system reliability height.Adopt multi-polar structure and double-stator structure (Chinese invention patent application number: ZL 200710020866.9) can further improve the power density and the efficient of motor, big application prospect is arranged.
When electric excitation biconvex electrode electric machine is used as DC generator, the star-like connection of phase winding, and by the full-bridge rectifier output DC, as shown in Figure 1.Be subjected to factor affecting such as phase winding inductance and full-bridge rectifier diode steering, use the output voltage of the double-salient-pole generator of full-bridge rectifier to descend with the load increase.Common power consumption equipment always wishes that supply power voltage remains unchanged.The motor excitation regulating system keeps terminal voltage constant by increasing exciting current, thereby has increased the excitation loss of system.Therefore, from the basic electromagnetic characteristic of electric excitation biconvex electrode electric machine, the biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism that proposition has low-voltage regulation and low excitation loss becomes original intention of the present invention.
Three, summary of the invention
The objective of the invention is: overcome the deficiencies in the prior art, proposed a kind of biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism with low-voltage regulation and low excitation loss.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention, form by electric excitation biconvex electrode electric machine and diode, the positive direction of electric excitation biconvex electrode electric machine phase winding electromotive force and magnetic flux positive direction meet the right-handed helix relation, and the positive direction of phase winding electromotive force is pointed to the anode of winding.The negative terminal or the anode of all phase windings link together, and draw through lead, do the negative pole or anodal use of biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism.The anode of every phase winding or negative terminal connect the male or female of diode respectively, and the negative electrode of diode or anode are connected to a bit, draw through lead, and the negative or positive electrode of making biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism uses.The positive pole of biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism and negative pole connect the positive pole and the negative pole of load respectively, to electric.Regulate the size of exciting current, i.e. the output voltage of scalable biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism, thus keep output voltage constant.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention, the principle of its realization is: the phase winding magnetic linkage of electric excitation biconvex electrode electric machine is relevant with rotor-position, and when rotor pole slipped into stator poles, unloaded magnetic linkage increased, and winding induces negative electromotive force.If this stage motor powers to the load, by Lenz's law as can be known, the magnetic linkage that load current produces stops unloaded magnetic linkage to increase, and is the degaussing armature reaction, causes electromotive force to reduce; When rotor pole skidded off stator poles, unloaded magnetic linkage reduced, and winding induces positive electromotive force.If this stage motor powers to the load, by Lenz's law as can be known, the magnetic linkage that load current produces stops unloaded magnetic linkage to reduce, and for increasing the magnetic armature reaction, causes electromotive force to raise.Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism skids off the stage of stator poles to electric at rotor pole, utilization increases magnetic armature reacts and offsets or weaken the loss of voltage that factors such as phase winding inductance and full-bridge rectifier diode steering cause, thereby reduces the voltage regulation and the excitation loss of motor.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention, when the work of little exciting current, the motor magnetic circuit is unsaturated, and increasing electromotive force rising amplitude that the magnetic armature reaction produces increases with the increase of load; When big exciting current is worked, the motor magnetic circuit is saturated, increase with load, increase the electromotive force rising amplitude reduction that the magnetic armature reaction produces, but simultaneously because magnetic circuit is saturated, the loss of voltage that phase winding inductance and diode steering process cause is also all corresponding to be reduced, so under the different exciting electric current, all there are low voltage regulation and excitation loss in system.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention, if the reversal of diode of phase winding, the external characteristic of system can be very soft.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention is applicable to all versions of electric excitation biconvex electrode electric machine of the different numbers of phases.
Biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism of the present invention, compared with prior art, basic electromagnetic characteristic from electric excitation biconvex electrode electric machine, utilize the magnetic armature that increases of load to react voltage regulation and the excitation loss that reduces motor, the electric current that increases the magnetic armature reaction is a load current, do not increase excess loss, thereby improve the performance and the efficient of biconvex electrode electromotor for magnetic enhancing power generation excitation magnetism.
