Abstract
The invention discloses a three-phase asynchronous motor used in a pump. The three-phase asynchronous motor comprises a housing, a left end cover and a right end cover which are respectively connected on a left end and a right end of the housing on by bolts, and a spindle disposed through a center of the left end cover and the end right cover. The spindle and the left end cover are connected by a bearing, and the spindle and the right end cover are connected by a bearing. A rotor is provided on a position of the spindle which is inside the housing. A stator is disposed on outside of the rotor. The right end cover is connected with a fan cover, and a fan is disposed on a position of the spindle which is inside the fan cover. A junction box is connected on a front part of the housing. The three-phase asynchronous motor is advantaged by simple structure, good heat dispersion, and stable operation.
Description
Technical field:
The present invention relates to motor, particularly a kind of pump is used threephase asynchronous.
Background technology:
The rotor of threephase asynchronous because of and magnetic field between exist the electromotive force and the electric current of caused by relative motion; Relativity through with magnetic field produces electromagnetic torque; Thereby realize the conversion of energy; But existing threephase motor is working long hours down, and the stator winding caloric value is big, influences the useful life of motor.
Summary of the invention:
The objective of the invention is provides a kind of simple in structure in order to overcome above deficiency, perfect heat-dissipating, and stable pump is used threephase asynchronous.
The object of the invention is realized through following technical scheme: a kind of pump is used threephase asynchronous; Comprise housing, the right ends of housing is connected with left end cap and right end cap through bolt respectively, and left end cap and right end cap center are run through and be provided with a rotating shaft; All be connected between rotating shaft and left end cap and the right end cap through bearing; Rotating shaft is positioned on the position of enclosure interior and is with rotor, and the outside of rotor is with stator, and right end cap is connected with fan shroud; Rotating shaft places on the inner position of fan shroud and is connected with blower fan, and the front portion of housing is connected with terminal box.
The present invention compared with prior art has the following advantages: through blower fan is installed in rotating shaft; Stator is when working long hours like this; It is constant that temperature can keep, and guaranteed the stability that motor works long hours, and can between the bearing surface of left end cap middle (center) bearing and left end cap, be provided with spring leaf; Form Elastic Contact like this, reduced the oscillation intensity of motor.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Label among the figure: 1-housing, 2-bolt, 3-left end cap, 4-right end cap, 5-rotating shaft, 6-bearing, 7-rotor, 8-stator, 9-fan shroud, 10-blower fan, 11-terminal box, 12-wavy spring sheet.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection range of the present invention.
Show the embodiment of a kind of pump of the present invention with threephase asynchronous like Fig. 1, comprise housing 1, the right ends of housing 1 is connected with left end cap 3 and right end cap 4 through bolt 2 respectively; Left end cap 3 runs through with right end cap 4 centers and is provided with a rotating shaft 5, all is connected through bearing 6 between rotating shaft 5 and left end cap 3 and the right end cap 4, and rotating shaft 5 is positioned on the position of housing 1 inside and is with rotor 7; The outside of rotor 7 is with stator 8, and right end cap 4 is connected with fan shroud 9, and rotating shaft 5 places on the inner position of fan shroud 9 and is connected with blower fan 10; The front portion of housing 1 is connected with terminal box 11; Through blower fan 10 is installed in rotating shaft 5, stator is when working long hours like this, and it is constant that temperature can keep; Guaranteed the stability that motor works long hours; Between the bearing surface of left end cap 3 middle (center) bearings 6 and left end cap, be provided with spring leaf, form Elastic Contact like this, reduced the oscillation intensity of motor.
