It also can work reversely. The rotor is simple and convenient, and the effect rate is high.
Description
Technical field
The utility model belongs to a kind of Constant Direct Current motor.
Background technology
Existing direct current machine mostly is alternating current machine and adds that the commutator transformation forms, and is not to be direct direct current machine, must must reduce as efficiency of motor through links such as parallel operation commutations, and manufacturing and maintenance cost also can increase thereupon simultaneously.In order to find the equipment of direct generation direct current, people have carried out many explorations.Application for a patent for invention prospectus as CN1320998A has just disclosed a kind of permanent direct current woman motor, put down in writing according to the document, its scheme is that the rotor with a radial is installed in the stationary magnetic field of being made up of permanent magnet, promote to change rotation by external force, direct current is sent in the motion that produces cutting magnetic line.The electric current that rotor produces is drawn by axle center and these two end points of periphery, with this power supply as external power supply.
The scheme of above-mentioned patent application is contained in rotor axis in the magnet piece, and the one, have difficulties on the manufacturing process, the 2nd, depletion takes place in the magnetic of magnet easily, and the electric power that sends can not guarantee " constant ".Therefore be necessary this scheme is improved.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, proposes a kind of new Constant Direct Current motor, novel structure, and magnetic field is stable, and rational in infrastructure, the direct current of output is constant, can reversely do work, and rotor is easy, and the efficient height is with through solving the deficiencies in the prior art.
This Constant Direct Current motor that the utility model proposes, it has rotor and stator, it is characterized in that rotor is that the conductor of a cylindrical shape is done rotor, two ends of rotor is mounted in the rotor shaft that rotates on its bearing, rotating shaft is connected transmission with the hydraulic turbine or steam turbine prime movers, stator is a coil, coil is one circular, between stator and rotor annular space is arranged, coil stationary is installed on the casing, and stator coil connects external dc power, to set up the stationary magnetic field, rotor shaft and rotor cylinder periphery are connected to brush respectively, the direct current that is produced are drawn, externally power supply.
The above-mentioned hydraulic turbine or steam turbine can replace with working machine, and two brushes connect the two poles of the earth of external dc power respectively, make whole device become the acting of motor driven working machine.
Stator coil with the insulation shell jacket circlewise.
The part that brush contacts with rotor is rotor shaft and rotor post.
The fixed form of rotor is identical or close with existing motor.
Characteristics of the present utility model are:
Novel structure, magnetic field is stable, and rational in infrastructure, output current is constant, does not need commutator, can reversely do work, and rotor is easy, renders a service high.

Embodiment
As Figure 1-3.Stator 5 is one group of coil, and stator is opened the effect of circle and put forward the connection DC power supply, and to set up constant magnetic field, the intensity in magnetic field is decided by the number of turn of size of current and coil.People can set the number of turn according to different power.The direction in the magnetic field of setting up behind the coil electricity determines that by the right-hand rule magnetic line of force all is parallel to axial line.Rotor is a conductor together with two ends rotor shaft 2 and rotor post 3, and material therefor mostly is metal.Rotor shaft is installed and fixed by corresponding bearing and bearing pedestal.One end of rotor shaft and outside power source are as connections such as the steam turbine or the hydraulic turbines, as with the shaft coupling connection etc.Rotor post part is consistent with the length of stator, and in general annular space 4 radially is the smaller the better between the two, but will consider the difficulty of manufacturing process, and factors such as both concentricitys, the depth of parallelism are advisable with 1-30mm.Stator coil generally is the shell jacket made from the insulating material such as plastics of a ring-type and is fixed on the casing, and casing is fixed on the support.The structure of this and common electric machine is basic identical.
Left side brush 1 is identical with the brush of existing motor with right brush 6.The part that brush contacts with rotor is rotor shaft and rotor post.
After the true back of the perfectly straight stream size of current of the coil turn of stator and institute, corresponding magnetic field has also just been determined thereupon.
The rotor that conductor is made is equivalent to numerous armature frame, and when rotor during by the external impetus device drives, these armature frames will be done the motion of cutting magnetic line, thereby produce direct current in the loop, and the constant DC source externally is provided.Here it is the utility model is as the operation principle of DC generator.
When the steam turbine that is connected with rotor shaft or the hydraulic turbine change working machine into, as rice mill, pulverizer etc., and when brush was connected DC power supply to rotor, rotor will be driven, and becomes direct current machine, drives working machine work.Here it is the utility model is as the operation principle of direct current machine.Change the input current size of input current size or change stator coil, rotating speed of motor will change thereupon.The principle of Here it is speed-regulated DC motor.
Through the test of easy midget plant, this Constant Direct Current motor of the present utility model is feasible.Output voltage (electric current) is constant.
Need to prove that at last this routine rotor post cross section can change over shapes such as ellipse, polygon, is that the direct current size of being exported can change to some extent.
