Embodiment
As shown in Figure 1, the invention 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 present invention implements 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 present invention and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention 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 present invention; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in claim scope of the present invention.
