Description

A kind of motor with intelligence control system

Technical field

The utility model relates to a kind of motor with intelligence control system.

Background technology

Motor is an electronic product common in commercial production and the daily life, and in electric machine structure, stator, rotor, end cap are the three big parts of forming motor.And end cap can be divided into: cast iron end cap, aluminium die casting end cap, thin plate stretching end cap or the like form.And aluminium die casting end cap is current mode relatively more commonly used.Existing end cap basically all is to have a monolithic case, and shell is provided with some through holes then.Owing to adopt monoblock cast, make the end cap easy deformation, when end cover body was connected with bearing pedestal, concentricity can not get assurance, and radiating effect is poor, and temperature rise is higher, and the use aluminum is more, and cost is higher relatively.

The utility model content

The technical problem that the utility model will solve is: the motor that provide a kind of simple in structure, economical and practical, heat dispersion is high.

In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopted and is:

A kind of motor with intelligence control system; Structure comprises the end cap at machine shaft, intelligence control system, rotor, stator, fan blade and stator two ends; Said intelligence control system; Comprise a microprocessor, this microprocessor is connected with LCD display circuit, A/D change-over circuit, failure indicating circuit, output driving circuit, keyboard control circuit and signal input circuit respectively; Said A/D change-over circuit is connected with three-phase voltage input sampling circuit, three-phase current input sampling circuit, pressure sensor input sampling circuit, temperature sensor input sampling circuit and velocity transducer input sampling circuit; Be connected through bolt between said end cap and the stator, be provided with 4 convexities on the said end cap at least, this convexity is uniformly distributed on the end cap; Said convexity is connected with said stator engaging, and said end cap comprises end plate, plurality of fixed seat and a bearing chamber, and said bearing chamber is positioned at the end plate center; Connect through circumferential reinforcement between the said holder; Be connected through shaft orientation reinforcing rib between said end plate and the holder, said end plate, holder and bearing chamber are one-body molded, and said electric motor end cap comprises the rear end cap that front end housing is connected with fan blade; The end plate of said rear end cap is Openworks shape, and said holder is provided with axially extending bore.

The utility model has solved the defective that exists in the background technology, is connected the stator that can guarantee motor and the axiality of rotor with the engaging of stator through end cap, improves the useful life of motor, and the utility model is simple in structure; Economic and practical, adopt the structure of full open model to make the perfect heat-dissipating of motor, save cost; Production efficiency is high, and structural strength increases, and has reduced vibration; Reduced noise, end cap weight has reduced by 1/3, the getting a promotion of the processing performance of end cap.
