Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of advantageous torque threephase asynchronous.
Background technology
The moment threephase asynchronous is derivatives of threephase asynchronous, is its mechanical property with the difference of general threephase asynchronous.The breakdown torque of moment threephase asynchronous is near stall, but the scope of its steady running is comparatively wide, can be from nearly synchronous speed near stall.Because the mechanical property of moment threephase asynchronous is very soft, less load variations just can cause the corresponding change of motor shaft rotating speed.
The moment threephase asynchronous is mainly used in the coiling aspect, and at manufacture fields such as metal material, fiber, papermaking, plastics, rubber and electric wires, coiling is that last procedure also is most important one procedure.Along with the coiling of product, coil diameter increases gradually, in this process, require can both keep uniform tension force any time because tension force too conference cause that the thick book inequality of product, gauge or diameter of wire change, line footpath drawing-down even break; And the too small meeting of tension force makes coiling lax.The biggest factor of tension variation during coiling is that coil diameter increases gradually when being wound up into reel owing to product, and coiling moment also increases with the increase of coil diameter, and the speed of main transmission is changeless, therefore the reel rotating speed is reduced with the increase of coil diameter.The mechanical property of moment threephase asynchronous has satisfied above-mentioned requirements well.
Though the moment threephase asynchronous of prior art has satisfied above-mentioned performance requirement, but because it generally adopts silicon steel sheet to strike out flute profile, then brass rod being penetrated silicon steel sheet laminates in the columniform groove, two ends are welded in the red copper ring, the rotor of forming mouse-cage type, its structure and manufacturing process complexity; Or adopt seamless steel pipe as rotor, and though structure and technology are simple, its characteristic is soft, loss is big, heating is big, temperature rise, needs the strong cooling of ventilating.
The utility model content
The purpose of this utility model provides a kind of advantageous torque threephase asynchronous exactly in order to address the above problem.
The purpose of this utility model is achieved in that a kind of advantageous torque threephase asynchronous, comprise stator, rotor assembly, front end housing, rear end cap and be arranged on the fan in the rear end cap outside, described rotor assembly comprises axle and the rotor that is installed on the axle, described rotor comprises rotor punching, the mouse-cage type cast-aluminum rotor that described rotor is formed in one, front end at cast-aluminum rotor is equipped with the long fan blade of multi-disc, is equipped with a plurality of balance columns in the rear end of cast-aluminum rotor; Described rotor punching is equipped with a plurality of ventilation holes around paraxial hole.
Described long fan blade is six.
Described balance columns is six, can install packing ring additional on balance columns.
The shape approximation of the notch on the described rotor punching is trapezoidal.
The described ventilation hole that is arranged on the rotor punching is six.
The utility model moment threephase asynchronous makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1, because rotor structure adopts cast-aluminum rotor, and this cast-aluminum rotor adopts HRA-1 high resistant aluminium alloy casting to become mouse-cage type, and manufacturing process is simple, easy-formation;
2, because rotor structure adopts cast-aluminum rotor, and the front end of this cast-aluminum rotor is provided with long fan blade, do not have fan blade in the rear end of cast-aluminum rotor, only establish balance columns, so just form pressure differential at motor cavity, inhale in forming to stream mode, with the loss heat sucking-off that rotor produces, help heat radiation;
3, owing to the mid portion at rotor punching dashes six ventilating heat dissipating holes are arranged, form the thermal convection of another inner chamber, help heat radiation;
4, cast-aluminum rotor easy-formation, structure, technology easily realize, comparatively speaking, and the production efficiency height; And the hardness of cast-aluminum rotor is higher, the motor that moves between 800-1200 rev/min applicable to rotating speed;
5, because fan can be installed in the rear end of the motor that rotating speed moves, cold wind is directly blown into motor cavity between 800-1200 rev/min, realize inner cooling, cost is low and safe and reliable.
