Wherein: 1-casing; 2-terminal box; 3-front end housing; 4-brakes end cap; 5-motor shaft; 6-rotor; 7-stator; 8-ac electromechanical electricity-loss brake; 9-fan; 10-fan housing.
Embodiment
As shown in Figure 1, the utility model discloses the brake 3-phase asynchronous motor of a kind of YEJ3 series ultra high efficiency, comprise: casing 1, terminal box 2, front end housing 3, braking end cap 4, motor shaft 5, rotor 6, stator 7, ac electromechanical electricity-loss brake 8, fan 9, fan housing 10, described 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 braking 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 braking end cap 4 by bearing, and braking end cap 4 is stretched out in the rear end of motor shaft 5, 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 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 ac electromechanical electricity-loss brake 8 is connected with terminal box 2 by electric wire, described ac electromechanical electricity-loss brake 8 is connected with braking end cap 4 by clamping screw, the geared sleeve of described ac electromechanical electricity-loss brake 8 is connected with motor shaft 5 by key, described fan 9 is arranged on the rear end of motor shaft 5, described fan housing 10 is screwed in casing 1 rear end.
Described braking end cap 4 adopts grey cast-iron HT200 to make, and the right side rubbing surface of described braking end cap 4 is more smooth.
The utility model is to implement like this: terminal box 2 is for connecting external circuit, 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, the motor shaft 5 that rotarily drives of rotor 6 rotates, motor shaft 5 drives fan 10 rotations to carry out internal heat dissipating, because adopting polyester-imide enamel covered wire, makes the winding of stator 7, 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 extend 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, can meet up-to-date national energy consumption standard, and the utility model is by the electromagnetic power-off brake 8 of increasing exchanges, when ac electromechanical electricity-loss brake 8 is electrified by terminal box 2, the brake disc of ac electromechanical electricity-loss brake 8 is held, can not produce braking action, in the time of power-off, the brake disc of ac electromechanical electricity-loss brake 8 is released, and produce friction with braking end cap 4, engage with brake disc according to the geared sleeve of ac electromechanical electricity-loss brake 8 inside, and the geared sleeve of ac electromechanical electricity-loss brake 8 is connected with motor shaft 5 by key, thereby the brake disc of ac electromechanical electricity-loss brake 8 stops rapidly under frictional force effect, then the geared sleeve of electromagnetic power-off brake 8 inside also stops operating, thereby check rapidly motor shaft 5, so both reduced the waste of energy, and can be widely used in the quick stopping operating mode of the needs such as punch press, simultaneously because braking end cap 4 adopts grey cast-iron HT200 to make, wear-resisting, long service life, and because the right side rubbing surface of braking end cap 4 is more smooth, frictional force is large, be beneficial to braking.
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.
