The three-phase asynchronous motor special for the oil pump has the advantages of being simple in structure, good in cooling effect and long in service life.
Description
Technical field
The present invention relates to a kind of oil pump special three-phase asynchronous motor.
Background technology
At present, the rotating speed of three-phase asynchronous motor rotor is lower than the rotating speed of rotating magnetic field, rotor winding because of and magnetic field between exist relative motion induced electromotive force and electric current, and produce electromagnetic torque with magnetic field interaction, realize energy conversion.Because oil pump special three-phase asynchronous motor is in the time working, motor need to ceaselessly rotate, and can cause electric motor overheating, and traditional motor does not have radiator, and motor easily burns like this, increases cost, and has greatly shortened the useful life of motor.
Summary of the invention
The object of the invention is in order to overcome above deficiency, the oil pump special three-phase asynchronous motor of a kind of simple in structure, good heat dissipation effect, long working life is provided.
Object of the present invention is achieved through the following technical solutions: a kind of oil pump special three-phase asynchronous motor, comprise stator, stator one side is connected with end cap, rotor is installed in stator, rotor is connected in rotating shaft by bearing, rotor one side is provided with fan, the outside of end cap extends into a flange for fixing oil pump, stator is provided with ventilation hole, on end cap, be evenly provided with multiple heat-dissipating fin groups, each heat-dissipating fin group is provided with multiple heat-dissipating fins, and two adjacent heat-dissipating fins of each described heat-dissipating fin group are parallel to each other.
Further improvement of the present invention is: stator interior adopts silicon steel sheet to make, and silicon steel sheet thickness is 0.5mm.
Further improvement of the present invention is: the shell bottom of stator is provided with base.
The present invention compared with prior art has the following advantages: stator is provided with ventilation hole, can well breathe freely, dispel the heat, on end cap, be evenly provided with multiple heat-dissipating fin groups, each heat-dissipating fin group is provided with multiple heat-dissipating fins, area of dissipation is large, good heat dissipation effect, is difficult for infringement rotor, the long working life of motor.
