Abstract
Tjhe general-purpose energy-saving multi-speed full-winding asynchronous machine described by present invention belongs to a multi-specification change-pole multi-speed asynchronous motor. Its structure is characterized by that its all the three-phase windings with different forms are full load windings, and the total amount of lead taps of motor winding is limited between 6-15 taps, and according to the different wire-connecting modes of change-pole windings its combination form can be made up by rotating speed or magnetic pole ratio. The optimized designing method, coil-inserting method and tapped wire-connecting method of this change-pole winding practically are the application of "Generalized multi-variable discrete function optimization" in change-pole motor. It can be extensively applied in the fields of machine tool, blower fan, paper-making and hoisting, etc. having need of multi-speed transmission.
Description
Multispeed asynchronous motor of the present invention is meant a kind of complete winding asynchronous motor of weight energy-saving multi-speed that comprises 21 series, about 200 different capabilities, specification, kind of novelty.It is after No. 88107625.2 patents of invention " energy-saving multi-speed asynchronous motor ", further developing after practice and prototype design, reduce 9～36 6～15 of reducing to the latter of the total lead riser number of multispeed asynchronous motor significantly by the former, approaching with 6～12 of the how fast machine of YD series of every fast 3 lead risers.But the invention belongs to the how fast machine new range of dominance energy, its industrial application broadness.No matter full winding is meant how fast machine and is two, three, four speed, no matter no matter winding is the single or multiple lift winding a plurality of stride values or division coil, all whole current-carrying of each winding of motor are arranged.
The present invention is derived from the new motor series that reform forms on Y series single speed machine basis, express with code name QYD for sake of convenience, i.e. weight, how fast Y type motor derivatives.The relevant prior art of the present invention is the JDO of the seventies
2The YD series multispeed asynchronous motor of the series and the eighties, the latter's overall performance level is with abroad the eighties, like product was approaching.YD series characteristics are double speed machine 6 lead risers, three fast machine 9 lead risers, four fast machine 12 lead risers, promptly every fast 3 lead risers.Its advantage is the minimum control apparatus of simplifying of lead riser number; Its deficiency is to lack multiple 6 lead risers in the double speed machine to contain the double speed machine that low or first gear, distal pole compare, and for example pole-changing is than being 2P
i=4/12; 4/16; 6/18; 6/24 etc.As existing JZ

22Or JZ
2-H
23Series (Dalian No.2 Electric Machine Factory's product) and BJZD
2Series (Jiamusi Electrical Machinery Plant's product) all be distal pole than double speed machine, but all uses two three phase windings that overlap, its total lead riser number also is a ∑
N=6, these double speed machines with weight single speed machine relatively, its power output and efficiency value all significantly descend.More than the YD series three fast machines, all be provided with two cover three phase windings of different stride values again, in service have only a cover winding to devote oneself to work, and winding current-carrying rate all has only 50% under each gear, so greatly reduce the output capacity and the efficiency value of motor.Get YD112M-4/6/8 and be example with weight Y112M-4 relatively, the former power output only has 1.5KW, efficient is 75%; The latter is 4.0KW, and efficient is 84.5%; With YD180L-4/6/8/12 four fast machines is example, and its minimum starting weight is 210Kg.And light-duty QYD90L-2/4/6/8 four fast machines of the present invention have only 27Kg, only are 13% of the former weight, and the stock utilization of visible YD series four fast machines is poorer.At existing problem in the above-mentioned prior art, design a kind of energy-saving multispeed whole-winding asynchronous machine series of rational in infrastructure, advanced technology, existing problem is very necessary in the prior art thereby overcome.
In view of existing problem in the above-mentioned existing all kinds of multi-speed asynchronous machine technology, the objective of the invention is to keep as far as possible the advantage of YD serial motors, overcome its shortcoming.Utilize " broad sense multivariable discrete function optimum seeking method " in the motor pole-changing, to use, invent a kind of novel multispeed asynchronous motor series to adapt to the needs of departments such as energy-saving multi-speed blower fan, permanent power multi-change speed bench drill and boats and ships, metallurgy, crane for dominance energy multispeed asynchronous motor.
Its mechanical structure of energy-saving multispeed whole-winding asynchronous machine series of the present invention is seen accompanying drawing 1, and it mainly is made up of support, stator core, rotor, rotating shaft etc.Three-phase stator winding is different from Y type single speed asynchronous machine, can be single cover, two cover or overlap winding more that during pole changing, each overlaps the equal current-carrying of winding, by special sub-winding grouping connection, the complete winding asynchronous machine series of three-phase winding connection mode M gained when optimizing pole-changing.It is similar to the YD serial motors also double speed, three speed, four speed, can select for the practical application of multi-change speed industrial circle, with whole 9 serial motors of YD relatively, motor of the present invention expands to 21 series.The power output of certain rotating speed shelves and efficiency value must be arranged in the how fast machine of this serial arbitrary specification and with weight single speed machine near (or low slightly).The deficiency of this serial motors is than every fast 3 lead risers of YD serial motors increase to be arranged slightly, and total lead riser number of this serial motors double speed～four speed is a ∑
N=6～15.The advantage of this serial motors is dominance energy such as light weight, high efficiency, high output, permanent power, wide speed ratio, many kinds, wide purposes.
Another characteristics of this multispeed asynchronous motor series mechanical structure are the complete general Y series single speed machines of outlet box, but relatively the latter simplifies terminal block, binding post and the positioners such as nut, packing ring that save in the terminal box, whole 6～15 of this serial motors is free end, airtight being positioned in the terminal box.
Why this serial motors has the dominance of multi-series like this, many kinds can multispeed asynchronous motor, and its reason is a practical studies in the multispeed electric machine, and best pole-changing is counted 2P
