Background technology
The special three-phase asynchronous motor of frequency control has been widely used in many fields, but the special three-phase asynchronous electrical machine energy-saving effect of existing frequency control is bad, do not meet the requirement of GB/T4942-1-2006 to electrical machine energy-saving reduction of discharging aspect, and the fan of the special three-phase asynchronous motor internal of existing frequency control is mainly arranged on motor shaft, when the speed of motor shaft reduces, this just may cause the rotating speed of fan to slow down, radiating effect is variation thereupon just also, and the long-term poor words of radiating effect will cause the lifetime of motor integral body.
Utility model content
For solving the defect of prior art scheme, the utility model discloses the special three-phase asynchronous motor of YVF3 series frequency control of a kind of good energy-conserving effect, good heat dissipation effect.
The utility model discloses the special three-phase asynchronous motor of a kind of YVF3 series ultra high efficiency frequency control, comprise: casing, frequency converter terminal box, front end housing, rear end cap, motor shaft, rotor, stator, fan housing, fan terminal box, fan, described frequency converter terminal box is arranged on casing outside by screw, described front end housing is arranged on casing front end by screw, described rear end cap is arranged on the rear portion of casing by screw, described motor shaft is arranged on front end housing and rear end cap, described rotor is fixed on motor shaft by the mode of hot jacket, described stator is installed in casing inside, described stator and the iron core of rotor all adopt that 50ww470 silicon steel sheet is cold rolling to be formed, described frequency converter terminal box is connected with the winding of stator by lead wire, the winding of described stator adopts polyester-imide enamel covered wire to make, described fan housing is screwed in casing rear end, described fan terminal box is screwed on casing, described fan is arranged on fan housing inside, described fan is connected with fan terminal box by lead wire, described fan and motor shaft are on same axis.
Owing to adopting technique scheme, the utlity model has following useful advantage:
1, good energy-conserving effect;
2, good heat dissipation effect;
3, long service life.
Accompanying drawing explanation

Wherein: 1-casing; 2-frequency converter terminal box; 3-front end housing; 4-rear end cap; 5-motor shaft; 6-rotor; 7-stator; 8-fan housing; 9-fan terminal box; 10-fan.
Embodiment
As shown in Figure 1, the utility model discloses the special three-phase asynchronous motor of a kind of YVF3 series ultra high efficiency frequency control, comprise: casing 1, frequency converter terminal box 2, front end housing 3, rear end cap 4, motor shaft 5, rotor 6, stator 7, fan housing 8, fan terminal box 9, fan 10, described frequency converter terminal box 2 is arranged on casing 1 outside by screw, described front end housing 3 is arranged on casing 1 front end by screw, described rear end cap 4 is arranged on the rear portion of casing 1 by screw, described motor shaft 5 is arranged on front end housing 3 and rear end cap 4, described rotor 6 is fixed on motor shaft 5 by the mode of hot jacket, described stator 7 is installed in casing 1 inside, described stator 7 and the iron core of rotor 6 all adopt that 50ww470 silicon steel sheet is cold rolling to be formed, described frequency converter terminal box 2 is connected with the winding of stator 7 by lead wire, the winding of described stator 7 adopts polyester-imide enamel covered wire to make, described fan housing 8 is screwed in casing 1 rear end, described fan terminal box 9 is screwed on casing 1, described fan 10 is arranged on fan housing 8 inside, described fan 10 is connected with fan terminal box 9 by lead wire, described fan 10 and motor shaft 5 are on same axis.
The utility model is to implement like this: frequency converter terminal box 2 is for connecting outside frequency converter, frequency converter terminal box 2 is connected with the winding of stator 7 by lead wire, stator 7 passes into after electric current, form rotating magnetic field, rotor 6 because of and magnetic field between exist relative motion induced electromotive force and electric current, be that rotating magnetic field and rotor 6 exist relative rotation speed, and produce electromagnetic torque with magnetic field interaction, rotor 6 is turned over, realize electric energy to mechanical energy energy conversion, thereby the rotation drive motor axle of rotor 65 rotates, because the winding employing polyester-imide enamel covered wire of stator 7 is made, because polyester-imide enamel covered wire has the advantages such as the good and resistance of resistance to elevated temperatures is little, both reduced the loss of electric current, economize on electricity obviously, effectively extended again the useful life of the winding of stator 7, and to have electrical efficiency high due to 50ww470 silicon steel sheet, the advantages such as magnetic disturbance is little, the iron core of stator 7 and rotor 6 all adopts that 50ww470 silicon steel sheet is cold rolling to be formed, can effectively improve the energy conversion efficiency of motor, and can meet up-to-date national energy consumption standard, fan terminal box 9 is for connecting 380V, the power supply of 50HZ, fan 10 is connected with fan terminal box 9 by lead wire, fan 10 rotary speeies are constant like this, can not change rotary speed along with the speed of motor shaft 5 rotary speeies, thereby while having avoided reducing because of electric machine frequency, thereby reducing, motor shaft 5 velocities of rotation bring fan 10 rotary speeies to reduce the defect that causes cold air blast velocity to reduce and make radiating effect variation, also avoided the defect that causes bulk life time to shorten because radiating effect is bad simultaneously.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
