Description
Technical field
The present invention relates to a kind of three-phase single hop multiple-pole switching reluctance motor, relate in particular to three-phase single hop and two section multiple-pole switching reluctance motor.
Background technology
At present, switched reluctance machines is the switching mode motor of double-salient-pole, is wound with concentrated winding on its stator poles; This motor can be divided into single-phase, three-phase, four phase switch reluctance motors by the number of phases, wherein 8/6 structure is in the majority mutually with three-phase 6/4,12/8, four again, that switched reluctance machines has is simple in structure, be easy to make, be easy to speed governing, reliable, not fragile, the advantages such as power factor is high, operational efficiency is high, detent torque is large, starting current is little, overload capacity is strong, energy heavy load starting, and good in high speed constant power district wide ranges performance.
Switched reluctance machines is along with the number of phases and number of poles increases, and step angle will reduce, and is conducive to torque ripple reduction, makes the startability of motor, stable performance better, and noise is also less, and the vibration of motor is just less.Controlling cost but the increase number of phases will increase, increase number of poles the motor pole area is reduced, therefore is to increase the number of phases or increase number of poles electric machine structure complexity, volume will be increased.
Existing switched reluctance machines only has three-phase 6/4, four phases 8/6, three-phase 12/8, because two-phase 4/2, two-phase 8/4 are arranged in theory, but can not go out product, and this is because they are difficult to self-starting, even auxiliary starter does not reach the operation torque yet.And greater than three-phase 12/8 be exactly three-phase 12/10, five mutually 10/4, five mutually 10/8, seven mutually 14/12, three-phase 24/32,,,,, etc. combination, these combinations have not only increased the number of phases, simultaneously also increased the control difficulty, the increase of the number of phases just equals the increase of cost; Only have at most mutually two pairs of magnetic poles to enter work done state (such as three-phase 12/8) and motor is every in commutation process, namely only has 1/3 magnetic pole of the total magnetic pole of motor in work done, what have is even 1/4,1/5 in work done, the cause that area reduces, the magnetic energy area is little that this volume that has just formed switched reluctance machines is large, unilateral magnetic force is large, noise and vibration is large, magnetic energy conversion Ψ-i surrounds.
The patent of invention that I have applied for, application number 200910117477.7, name is called " Double stator-rotor multiple-pole switching reluctance ", the armature number of magnetic poles is 2 times of rotor magnetic pole number in this patented technology, but under the single hop state, can start operation, because it is very little with the operation torque to be not activated moment under the single hop state, thus single hop (separate unit) can not be done, and can only be applicable to two sections (separate unit).
Switched reluctance machines is compared with the Same Efficieney AC three-phase motor, the regular tap reluctance motor is than the large seat No. of AC three-phase motor, the high performance switch reluctance motor is than large two seat No. of AC three-phase motor, and AC three-phase motor only needs the simple operation electric switch that starts, it is low to control cost, and switched reluctance machines is because belonging to electronic on-off-type, increase the number of phases and just mean the increase electronic switch, control cost thereby increased, its electronic switch control appliance accounts for switched reluctance machines cost 30%～40% according to the number of phases difference of switched reluctance machines, its price is higher more than 3～5 times than the price of common alternating current machine, has therefore affected applying and popularizing of switched reluctance machines.
At present, countries in the world are all being studied this New-type electric machine of switched reluctance machines, adopt single-chip microcomputer control technology in control technology, and there has been larger breakthrough application-specific integrated circuit (ASIC) modularization aspect, but industrialization and action oriented research work relatively lag behind, and especially what progress switched reluctance machines are not had itself.
