Description
Technical field: the three-phase linear asynchronous motor that the present invention relates to a kind of forced air cooling platypelloid type three edge works.
Background technology: at present the platypelloid type linear electric motors adopt single side type or double-flanged end mostly, winding construction be generally double-layer overlapped around mode.Because consider the assembling of iron core and the installation question of motor, the general design margin of yoke section of iron core is larger, and effective rate of utilization is low, the winding double-layer overlapped is larger around the end, and copper loss increases, and generally not only wastes material, and volume is large, and cost is high, can not satisfy the needs of industry-by-industry.Particularly be subject to the restriction of environment for use, requiring motor volume little, the occasion of the relatively large and continuous operation of thrust, traditional design concept can't realize the requirement used.For solving above-mentioned contradiction, when design of electrical motor, adopted the design of three edge works.
Summary of the invention: the purpose of this invention is to provide that a kind of propulsive efficiency is high, system energy consumption is low, the three-phase linear asynchronous motor of forced air cooling platypelloid type three edge works of compact conformation, the little easy care of noise.Technical scheme of the present invention is: a kind of three-phase linear asynchronous motor of forced air cooling platypelloid type three edge works, formed by primary and secondary, elementary by elementary iron core, and the winding that is positioned at elementary iron core consists of, cooling system adopts a Fans at least, assembling is in the fan supporter bottom, fan supporter and elementary iron core and winding overhang consist of the airtight ventilation air duct in two ends by the epoxy casting layer, mounting blocks is equipped with respectively in elementary iron core both sides, use location when installing as the client, back-up block is equipped with at elementary core length two ends, back-up block is connected with elementary iron core by the standard component hex bolts, be drilled with screw on the back-up block, offering user installation uses when fastening, elementary core design becomes the form of left and right sides symmetrical grooving, form the double surface grooving structure, winding is directly in entering iron core slot, the secondary channel steel type that is designed to, secondary structure adopts combined type secondary, current-carrying part aluminium alloy expanded material, shape is designed to grooved, and the installation groove of magnetic conduction iron yoke is all arranged on three limits of aluminium alloy expanded material, is higher than the plane of aluminium alloy expanded material after magnetic conduction iron yoke is installed; Magnetic conduction iron yoke is selected low-carbon steel material, and two sections of material is combined into one by bonding mode.The present invention had both reduced the loss of motor, had improved the efficient of motor, had increased simultaneously the mechanical strength of current-carrying part, had reduced secondary distortion, realized motor three edge works.
Operation principle of the present invention:
In the concentrated winding on the elementary iron core of double surface grooving, when passing into the three-phase symmetrical electric current, in elementary and secondary air gap, can produce the shifting magnetic field, under the effect of shifting magnetic field, closed grooved three limits are secondary can to produce induced electromotive force, because aluminium section bar is secondary current-carrying part, therefore the secondary middle meeting of three limit aluminium section bars produces induced current, induced current and shifting magnetic field interact, and namely produce electromagnetic push, make and produce relative motion between primary and secondary.Since the present invention be closed three limit aluminium section bars as secondary, so induced current loss minimizing, the induction linear asynchronous motor of the more former monolateral secondary work of pushing force density is large.
Technique effect of the present invention:
1, design of electrical motor is forced air cooling, and volume is little, and is lightweight, and pushing force density is large.
2, double surface grooving on the iron core makes motor form two main working faces, an attached working face, and motor three edge works have improved the utilance of material greatly, effectively reduce cost, have saved the space.
3, winding is for concentrating winding, and winding directly on iron core, has been saved the man-hour of rule, has shortened the end size of motor, makes the more compact structure of motor, has reduced copper loss, has improved the efficient of motor.
4, cooling system structure is compact, occupies little space, and air channel structure is reasonable, and wind flow is unobstructed, and good cooling results effectively reduces electric machine temperature rise.
5, the compact conformation of design of electrical motor, it is little to take up room; Convenient disassembly is installed reliably.
