Abstract
The invention relates to a novel three-phase asynchronous motor that is mainly applied to the motor field. The novel three-phase asynchronous motor includes a motor body; a front end cap and a rear end cap are respectively installed at the front side and the back side of the motor body; a stator winding and a rotor that is installed on a spindle are arranged in the motor body; a fan is arranged on the rear end cap; and a fan cover is arranged outside the fan. Two end portions of the spindle are arranged in a deep groove ball bearing that is arranged inside the front end cap and the rear end cap; and a wave form spring piece is arranged between the end surface of the deep groove ball bearing and the front end cap. According to the invention, a fan is installed on a rear end cap; therefore, when a stator and a rotor work for a long time, a constant temperature can be maintained; besides, a wave form spring piece is arranged between an end surface of a deep groove ball bearing and an end cap and thus elastic contact is formed, so that vibration strength of a motor is reduced, stability of the motor is improved, and service life of the motor is prolonged.
Description
Technical field
The present invention relates to electric motors, relate in particular to a kind of threephase asynchronous.
Background technology
Motor is the equipment that converts electric energy 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 novel threephase asynchronous is also very extensive; 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 practice thrift 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.
Summary of the invention
The present invention the purpose of this invention is to provide 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.
Technical scheme of the present invention is following:
A kind of threephase asynchronous; Comprise body, it is characterized in that: be separately installed with front end housing and rear end cap in the front and back of said body, be provided with stator winding in the body, be loaded on the rotor in the rotating shaft; Said rear end cap is provided with fan, at the outer setting fan housing of said fan.Also be provided with terminal box in said body upper.Two ends of said 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, between zanjon ball journal and front end housing backbone sealing ring are installed.Said front end housing and rear end cap are fixed by bolts to respectively on the housing, and bolt is provided with packing ring.The junction of stating between 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.
Fan is equipped with in the present invention on rear end cap, when stator and rotor work long hours, can keep temperature constant.
Reasonable in design of the present invention 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.
