Description
Technical field
The utility model belongs to techniques of linear motor field, particularly relates to a kind of concentratred winding formula linear electric motors.
Background technology
Linear electric motors a kind ofly cancel traditional intermediate conversion device, electric energy is directly changed into the source that is used as power and the driving mechanism of the mechanical energy of rectilinear motion.The double-deck distributed winding of the many employings of traditional linear electric motor primary, such motor production operation complex procedures, the equipment investment in early stage is larger, operating personnel's utilance is low, the Manufacture quality control of motor is complicated, simply by in-situ production management, be difficult to the production cost reducing single motor further.
The production process of existing concentratred winding inserts slot liner in the groove of iron core, the elementary iron core of insertion groove insulating paper is concentrated the coiling carrying out enamel-cover circle line, cause the forming requirements of the elementary slot liner of concentratred winding formula high like this, need to carry out shaping according to the shape of the inwall of elementary grooved.And because direct coiling is in elementary groove, enamelled wire be arranged with intersect and occur when high speed winding fine rule disorderly around etc. problem, motor copper factor is reduced, and increases the problems such as resistance unbalance rate, reduce electric efficiency.Therefore, need badly in the middle of prior art and a kind of novel technical scheme will solve this problem.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of concentratred winding linear electric motors, motor volume can be reduced, realize high power density, winding factor can be improved, and reduce linear electric motors material cost, save frock, save the production time, while linear electric motors production cost is reduced, improve electric efficiency.
Concentratred winding linear electric motors, comprise armature winding, elementary iron core and casing, described casing is rectangular flat structure, casing is laterally set up in parallel fluted; Described elementary iron core is arranged on the inside grooves of casing, and elementary iron core is provided with elementary iron core teeth; Described armature winding is rectangular hollow structure, and rectangle frame portion is formed by enameled sheet wire coiling, and armature winding is socketed in the elementary iron core teeth of elementary iron core.
The outer coil of the enameled sheet wire of described armature winding is closely wound around by insulating paper, and the joint summit place of insulating paper is bonded by glue, is shaped by insulating varnish in the end of the outer coil of enameled sheet wire.
By above-mentioned design, the utility model can bring following beneficial effect: concentratred winding linear electric motors, motor volume can be reduced, realize high power density, winding factor can be improved, and reduce linear electric motors material cost, save frock, save the production time, while linear electric motors production cost is reduced, improve electric efficiency.Adopt centralized winding, end size is little, saves raw material, makes motor coil resistance little, and copper loss reduces, and improves electric efficiency.And winding overhang is not overlapping, there is shorted-turn fault probability and reduce and save the production time of placing same dielectric; As adopted integer groove concentratred winding, winding factor reduces, therefore adopts fractional-slot concentratred winding, can improve winding factor; Armature winding adopts lenticular wire by square winding mould coiling, makes coil configuration neat, saves material, and improve copper factor, reduce resistance unbalance rate, improve electric efficiency.And can the multiple identical coil of coiling by a winding mould, each coil can be welded to each other according to design requirement, therefore can design plurality of specifications motor, saves frock; Insulating paper is closely wound around the primary coil completed with coiling outer, bonds in joint with glue, putting in elementary iron core.Solve the problem that the forming requirements of the elementary slot liner of concentratred winding formula is high, and save the time of inserting phase insulation paper, thus reduce the production cost of motor.
