Moment motor of continuous rotation block
Continuous stalling torque motor described in the utility model is a kind of novel torque motor, is employed desired electrical motivation in the industry production such as metallurgy, electric wire device cable, weaving, papermaking.
The multipole asynchronous torque motor that the prior art of this technical field is made up of housing, protecgulum, bonnet, stator, rotor.By as can be known to the performance test of domestic and international relevant torque motor, all there is short, big, temperature rise when nothing adds ventilation condition of electromagnetic sound when working of continuous stall time in present existing torque motor, and torque fluctuations is bigger within 5 hours of starting working.At the existing problem of said structure torque motor, improving design has been very necessary with characteristic and the operating efficiency that improves continuous stall.
In view of above-mentioned problems of the prior art, task of the present utility model is a kind of good manufacturability simple in structure, advanced in performance of design, is convenient to maintenance, and output torque is the advantageous torque motor of stall greatly continuously.The very big research topic of the previous difficulty of order is exactly the stability of characteristics that how to guarantee motor, make motor can be for a long time stall continuously, allow the characteristic curve of motor present nearly linear, the development of producing along with modernization industry, to the requirement of this ideal type torque motor more and more urgent as: steel rolling drags that base curls, braiding, wire drawing ... all need this ideal type torque motor.Continuous stalling torque motor described in the utility model has solved this difficult problem, by to the test of the model machine characteristic curve type linearly of motor as can be known, ideal characterisitics of the present utility model has not only been replenished a domestic blank, and the development of torque motor is entered a new phase.
The utility model is a kind of continuous stalling torque motor, and it has rotor, stator, housing, front end housing, rear end cap, bearing, and its feature has one group of notch as shown in drawings on the rotor punching of rotor, and the groove of rotor is several to be decided according to needs.In each notch of rotor punching, all be inserted with one group of metal sliver, and the end of one group of metal sliver in the same notch and the metal sliver end in each notch all linked together, thereby fix with rotor punching by the method for welding.Fin and back fin before the forward and backward two ends of rotor insert.Stator winding of the present utility model adopts double folding, and stator rabbet is selected the semi-closed port peariform slot, and stator is installed in the housing.On rotor, be installed with rotor punching, in each notch of rotor punching, all be inserted with one group of metal sliver, and the end of all metal slivers is linked together by the mode of welding.Fin and back fin before the forward and backward two ends of rotor insert.Bearing in the two end axles of rotor and front end housing and the rear end cap centre bore is connected.Front end housing all is to be connected with housing by hold-down screw with rear end cap.
Continuous stalling torque motor described in the utility model is through complete performance test of the test of Dalian middle and small motor, inspection center, and this motor properties surpasses the model machine level that West Germany De Make motor company produces.The utlity model has following characteristics: can fluid drive, but low speed turns round continuously again, and 8 pole motor asynchronous speed scopes can be the most a kind of torque motor of speed adjustable range from 725 rev/mins to 5 rev/mins.This torque motor changes sensitivity simultaneously, and speed change is even, need not add ventilation.Full force feed electricity is stall continuously, allows completely to press plugging, but the short time antiport, can several motor reels to the connection co-operation.In sum as can be known, the utility model is as the used ideal torque motor of traction.It can save lots of control equipments and circuit.The utility model can be widely used in steel rolling and drag on the equipment such as base curls, straddle truck calliper, wire drawing, lathe; Can also be applied to light industry aspects such as papermaking, weaving.Research of the present utility model successfully will finish the history that China introduces external torque motor.And will bring huge economic benefit to China's building of the four modernizations.
The utility model has two accompanying drawings, and wherein accompanying drawing 1 is the overall construction drawing of continuous stalling torque motor, and accompanying drawing 2 is side direction half cut-away views of general structure.
Among the figure: 1, rotor 2, front end housing 3, metal sliver 4, rotor punching 5, stator 6, rear end cap 7, bearing 8, hold-down screw 9, housing 10, hold-down screw 11, preceding fin 12, back fin 13, bearing
Specific embodiment of the utility model is shown in accompanying drawing 1, accompanying drawing 2, and this continuous stalling torque motor has rotor (1), stator (5), housing (9), front end housing (2), rear end cap (6), bearing (7,13).On the rotor punching (4) of rotor (1), have 44 notches, in each notch of rotor punching (4), all be inserted with one group 4 metal slivers (3), and the mode by welding all links together metal sliver (3) ends in the end of one group 4 metal slivers (3) in the same notch and 44 notches, thereby fixes with rotor punching (4).Fin (11) and back fin (12) before the forward and backward two ends of rotor (1) insert.The winding of the utility model stator (5) adopts double folding, and the notch of stator (5) is selected the semi-closed port peariform slot, and stator (5) is installed in the housing (9).On rotor (1), be installed with rotor punching (4), on rotor punching (4), have 44 notches, in each notch, all be inserted with 4 metal slivers (3), and the end of all metal slivers (3) linked together by the mode of welding.Fin (11) and back fin (12) before the rear and front end insert of rotor (1).Bearing (7,13) in the two end axles of rotor (1) and front end housing (2) and rear end cap (6) centre bore is connected.Front end housing (2) is to be connected with housing (9) by hold-down screw (8,10) with rear end cap (6).Model machine model among the utility model embodiment be JLLJ110-8 compare its characteristic with domestic and international different model torque motor can be for details see attached table 1, subordinate list 2.
