Abstract
The invention discloses a high-efficiency three-phase asynchronous motor. The high-efficiency three-phase asynchronous motor comprises a shell and is characterized in that a front end cover and a rear end cover are mounted in the front and in the rear of the shell respectively, a stator winding and a rotor mounted on a rotating shaft are arranged in the shell, the rotor comprises a rotor core, a guide strip and cast aluminum end rings, a fan is arranged on the rear end cover, a fan housing is arranged outside the fan and fixed on the rear end cover through screws, two ends of the rotating shaft are arranged in deep groove ball bearings in the front end cover and the rear end cover respectively, and the front end cover and the end face of the corresponding deep groove ball bearing are separated by a waveform spring piece. The front end cover and the end face of the corresponding deep groove ball bearing are separated by the waveform spring piece to form elastic contact, so that the vibration strength of the motor is reduced, the service life of the motor is prolonged, and the motor is good in radiating effect, simple, economical and applicable and has huge economic and social benefits and wide market prospect.
Description
Technical field:
The present invention relates to a kind of motor, particularly a kind of efficient threephase asynchronous machine, the temperature rise in the time of can reducing work, cost simple in structure is low.
Background technology:
Along with the progress and the expanding economy in epoch, the economic construction develop rapidly, motor as the power source application more and more widely, asynchronous motor be use in all kinds of motor the widest, that requirement is maximum is a kind of.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 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.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:
In order to address the above problem, the present invention provides a kind of efficient threephase asynchronous machine, and is simple in structure, good heat dissipation effect.
The technical scheme that the present invention adopts is: a kind of efficient threephase asynchronous machine; Comprise housing, it is characterized in that the front and back of housing are separately installed with front end housing and rear end cap, be provided with stator winding in the housing, be loaded on the rotor in the rotating shaft; Rotor comprises rotor core, sliver, cast aluminium end ring; Rear end cap is provided with fan, at the outer setting fan housing of fan, fan housing by screw on rear end cap; Two ends of 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.
