Abstract

The utility model relates to a generator, which is composed of end covers, a stator, a rotor, a fan, etc. The utility model has not a steel casting casing and the stator and the rotor of the utility model are directly fixed to the front end cover and the back end cover through a plurality of fixing screw rods; a silicon steel sheet set is provided with a plurality of pore canals for ventilation; the fan of the generator can blow through the pore canals for ventilation. The generator has simple structure and particularly solves the problem of heat radiation of a motor; in addition, the utility model has the advantages of small volume, low cost, long service life, material saving and energy saving. The utility model can be particularly used as the substitution product which presently uses a generator with small power.

Description

A kind of generator

The utility model relates to a kind of generator.

Existing small power generator, its structure is at stator silicon steel plate and adds the steel-casting shell, and the heat that produces in the electric power generation process passes on the shell fin by stator silicon steel plate and dispels the heat.It is big that said structure exists motor volume, and heat radiation is slow, makes complexity, and consumptive material is many, defectives such as big energy-consuming.

The purpose of this utility model just is to provide a kind of no cast steel shell, and volume is little, good heat dissipation effect, the novel electricity generator of long service life.

The purpose of this utility model is achieved in that by front and rear cover motor stator and rotor is directly fixing, cancels former cast steel shell; Its winding mode and connect electric mode and be same as common generator; In the stator silicon steel plate group, make some ventilating hole channels, make electric motor fan blowing energy passing hole channel; During use, motor is fixed by the front and rear cover foot bolt.

The utility model dwindles motor volume owing to take said structure greatly, generally can alleviate motor weight about 30%, has saved sheathing material, and cost reduces.Owing to there is not a shell, the generator heat radiation obviously improves, and in addition, is provided with ventilating hole channel in the silicon steel sheet group, and more sharp have a motor radiating, motor can be for a long time near running at normal temperature, long service life, reactive power consumption is few, generally energy-conservation approximately 10-15%.In addition, the power of being used to that former generator operation produces is to pass to shell through end cap, passes on the under-chassis seat that is connected with shell again, tends to take place generator from quivering phenomenon, and motor of the present utility model operation is used to power and is directly passed on the end cap pin through end cap, has solved the problem of quivering certainly of generator at one stroke.

Be further elaborated below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the end cover structure schematic diagram

Accompanying drawing 3 is a stator ventilating hole channel schematic diagram

The sequence number of marking is expressed as follows respectively in the accompanying drawing: 1, front end housing; 2, dust cover; 3, rotating shaft; 4, end cap pin; 5, standing screw; 6, stator; 7, stator ventilating hole channel; 8, rotor; 9, rear end cap; 10, fan; 11, fan cover cap; 12, end cap pin fixed bolt hole; 13, strengthen width of cloth bar; 14, stator winding.

This generator consists of stator 6 and rotor by front and rear cover, stator, rotor, fan etc. 8 place between drive end bearing bracket 1 and the rear end cap 9, and forward and backward end cap by several standing screws 5 admittedly Fixed; Fan cover 11 links to each other with rear end cap, and fan 10 is positioned at fan cover 11, with Rotating shaft 3 links to each other; Dust cover 2 but does not cover ventilating hole channel between end cap and stator and rotor, Its effect is to prevent that dust etc. from entering stator and internal rotor; If processing in the stator silicon steel plate group Dried ventilating hole channel 7, the blowing of fan 10 can be played cooling, heat radiation work through this ventilating hole channel With; End cap 1,9 structures are identical, and top is rounded, and hollow has several reinforcement spokes 13, Strengthen width of cloth bar 13 and mainly play a part to improve end cap intensity, the end cap bottom is end cap pin 4, should The end cap pin has fixed bolt hole 12 as the generator under-chassis on the end cap pin, can make generator solid Fix on the under-chassis seat.

Embodiment: power output is 10 kilowatts a generator, and forward and backward end cap can be used steel-casting, and circular portion is provided with three and strengthens width of cloth bar; Standing screw with three diameter 20mm is fixed, and its fixed position such as accompanying drawing 2 connect suspension ring, so that motor moves on the top screws centre position; Stator, rotor size and winding are equal to the generator with power, process ventilating hole channel on the stator silicon steel plate group, and as accompanying drawing 3, ventilating hole channel is positioned at winding space, the about 7mm of channel diameter; Dust cover is optional made of plastic, strengthens width of cloth bar with three spring one ends and end cap and links to each other, and other end compressing dust cover makes it fixing.
