Abstract
The utility model relates to a three-phase asynchronous motor which comprises a shell. A front end cover and a rear end cover are respectively installed at the front and the rear of the shell; the shell is internally provided with a stator winding and a rotor arranged on a rotating shaft; the rear end cover is provided with a fan which is externally provided with a fan cover; the two end parts of the rotating shaft are arranged in deep groove ball bearings which are arranged in the front end cover and the rear end cover; and the end surface of the deep groove ball bearing and the front end cover is separated from each other by a wave-shaped spring piece. The rear end cover is provided with the fan, so that the temperature is maintained to be constant when a stator and the rotor work for a long time; and the end surface of the deep groove ball bearing and the front end cover is separated from each other by the a wave-shaped spring piece, so that elastic contact is formed, and the vibration strength of the motor is reduced.
Description
Technical field
The utility model relates to electric motors, relates in particular to a kind of threephase asynchronous.
Background technology
Motor is the equipment that electric energy is converted to mechanical energy, and in machinery, metallurgy, oil, coal, chemistry, aviation, traffic, agricultural and other various industry, motor is being widely used.Along with industrial automatization improves constantly, need to adopt the element of various control motors as automated system, in the automatic control system of artificial satellite, motor also is indispensable.(in the modern household electrical appliances industry) motor also should use more and more widely in this external national defence, culture and education, medical treatment and the daily life.
The use of threephase asynchronous is also very extensive, and the rotating speed of its rotor must be lower than the rotating speed of rotating magnetic field, the 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.Compare with monopole asynchronous motor, the threephase asynchronous runnability is good, and can save various materials.But owing to work long hours down, the stator winding caloric value is big, has brought to life-span of motor to have a strong impact on.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and resistance to shock is good, good heat dissipation effect, the threephase asynchronous that long-time running is stable.
The technical solution of the utility model is as follows:
A kind of threephase asynchronous, comprise housing, it is characterized in that: be separately installed with front end housing and rear end cap in the front and back of described housing, be provided with stator winding in the housing, be loaded on the rotor in the rotating shaft, described rear end cap is provided with fan, at the outer setting fan housing of described fan.
Also be provided with terminal box on described housing top.
Two ends of described rotating shaft are arranged in the deep groove ball bearing in front end housing and the rear end cap, are separated with the wavy spring sheet between deep groove ball bearing end face and the front end housing.
Described front end housing and rear end cap are fixed by bolts to respectively on the housing, and bolt is provided with packing ring.
Junction between described rear end cap and the rotor is provided with back-up ring, and fan housing is screwed on rear end cap after being arranged on outside the fan.
The utility model is equipped with fan on rear end cap, when stator and rotor work long hours, can keep temperature constant.
The utility model reasonable in design is separated with the wavy spring sheet between deep groove ball bearing end face and front end housing, formed Elastic Contact, has reduced the oscillation intensity of motor, has increased the useful life of motor.
