Abstract
The utility model provides a cylindrical three-phase linear induction motor, comprising a primary which consists of primary iron core, primary winding and magnet yoke, and a secondary. The primary iron core is in a ring shape, and every iron core is excavated with vortex block slot; the primary winding is in a cake shape consisting of a coil framework made of insulating material and the coil wound on the framework; the primary iron core and the primary winding are arranged at intervals to form a cylindrical primary; the secondary is arranged inside the primary, and the magnet yoke is enclosed the primary. The utility model has the advantages that: the structure is simple, the cost is low, the energy is saved and the speed is high; the exchange of frequency and the speed regulation can be carried out directly; the noise is low, the stroke is long and the maintenance is convenient; no pollution.
Description
(1) technical field
The utility model relates to a kind of motor.
(2) background technology
Conventional motors is made up of rotor and stator, its output be revolving force.In many linear drive apparatus or system, all be to adopt electric rotating machine to be converted to rectilinear motion, or realize by cylinder, oil cylinder by mechanisms such as chain, steel wire rope, driving-belt, gear or screw mandrels.Because there are the intermediate conversion transmission mechanism in these devices or system, it is slow all to exist mechanism's loss, noise, stroke limiting system and speed, and problems such as maintenance difficult are so machine volume is big, efficient is low, precision is low.If adopt linear motor driving just can overcome these deficiencies.Important a kind of in the linear electric motors is cylindrical linear.It is made up of elementary, secondary.In prior art,, can not form large batch of suitability for industrialized production owing to can not overcome problems such as complex structure, the loss of cylindrical linear are big, cost height.
(3) summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, with low cost, cylinder type three-phase linear asynchronous motor that loss is little.The purpose of this utility model is achieved in that it comprises the primary and secondary of being made up of elementary iron core, elementary winding, yoke, elementary iron core is the ring-type iron core, and all have the eddy current partition grooves on each iron core, the coil rack that elementary winding is made by insulating material and be wrapped in the pie winding that the coil on the skeleton is formed, it is cylindric elementary that elementary iron core and elementary winding are spaced formation, secondary be arranged in elementary, yoke wrap in elementary outside.Advantage of the present utility model is: (1) can significantly reduce eddy current because elementary iron core has the eddy current partition grooves, and efficiency of motor is improved, and thrust improves can reach 15%, helps energy savings, more economical use; (2) adopt pie winding, improved the utilance of copper cash, can save copper cash, reduced copper loss, compare with flat linear electric motors, reduced the loss of electric machine, improved electric efficiency, increase the thrust of motor, reduced the volume of motor, alleviated the weight of motor; (3) stroke of cylinder type three-phase linear asynchronous motor can be realized by inferior level length as required, therefore can set flexibly; (4) yoke is again the shell of motor simultaneously.In a word, device of the present utility model has simple in structure, and is cheap, energy savings, speed height, but Direct Conversion speed governing, advantage such as noise is low, and stroke is long, and is pollution-free, easy to maintenance.Has extensive applicability.Can replace mechanisms such as the sprocket wheel chain that drives by electric rotating machine, rack-and-pinion, crank connecting link and realize straight-line type of drive; Also alternative cylinder or oil cylinder moving linearly.For example: with the elevator of linear motor driving of the present utility model can realize not having machine room, wireless, no counterweight.Also can be used as punch press etc. and need the driving power source of the machine tool etc. of moving linearly.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of elementary iron core.
(5) specific embodiments
For a more detailed description to the utility model for example below in conjunction with accompanying drawing: in conjunction with Fig. 1, the composition of cylinder type three-phase linear asynchronous motor comprises the primary and secondary of being made up of elementary iron core 2, elementary winding 3, yoke 41.In conjunction with Fig. 2, elementary iron core is the ring-type iron core, and all has the eddy current partition grooves on each iron core, the coil rack that elementary winding is made by insulating material and be wrapped in the pie winding that the coil on the skeleton is formed.Elementary iron core and elementary winding are spaced, and it is cylindric elementary that yoke wraps in elementary outer formation.Yoke is wherein made by low carbon steel pipe, be yoke be again electric machine casing.Secondary be arranged in elementary.The sliding bearing 6 that elementary end is provided with motor cover 5, adopts engineering plastics to make.Its operation principle is: primary magnetic field is open magnetic field, produces air-gap field behind the feeding symmetrical sine electric current in three phase windings, and the distribution situation of its air-gap field is similar to electric rotating machine, is that the rectilinear direction that spreads apart is Sine distribution.When three-phase current changed in time, air-gap field prolonged straight line by directed phase sequence and moves, and is translation, is called travelling-magnetic-field.Under the secondary ripple magnetic field intercepts of being expert at, induced electromotive force also produces electric current, just and secondary electric current and air gap magnetic field interaction produce electromagnetic push, as elementary be fixed, secondaryly just do rectilinear motion along the travelling-magnetic-field travel direction.
