Technical field
The invention provides a kind of direct current machine, particularly a kind of motor of compound efficient rate.
Background technology
Existing direct current machine is all made up of single rotor and single stator.The solenoid of rotor or stator is energized to generate an electromagnetic field, and then constantly changes the magnetic direction of solenoid according to the logical order of rotor turns, to realize the Power output of motor with carbon brush type commutator or brushless control circuit.
This type of motor is by the limitation of structure, and only produce magnetic field at the single phase tangent plane of rotor and stator, the effect that utilizes of electric energy is not very large.Again, if need enough power stages, need constantly to strengthen overall dimension, therefore space availability ratio is limited.
Summary of the invention
For above-mentioned defect, the invention provides a kind of motor of compound efficient rate.Main innovate point of the present invention is that the rotor of motor and stator are all with the patten's design of combined type, for multi-turn composite type is unshakable in one's determination, namely stator is overlapped in rotor core, and rotor is overlapped in stator core again, is all fully used in the magnetic field, inner and outer of rotor and stator core.
Technical scheme of the present invention is:
A kind of direct current machine, comprise rotor core group 1, stator core group 2, connecting axle 3, bearing 4, stator base 5, rotor base 6, flange 7, described rotor core group 1 packs in stator core group 2 with concentric shafts; In stator base 5 with the annular space of rotor spindle nose 10, stud with bearing 4, blocking in stator base 5 with the annular slot of bearing 4 outer has jump ring 8; Be connected with flange 7 with on the rotor spindle nose 10 of screw, fixed by bolt and connecting axle 3.
Stator core group 2 refers to coiling solenoid on single silicon steel plate core, every single iron core distinguishes the whole circle of composition group unshakable in one's determination with the difference of internal diameter size, whole circle iron core group is upper places band screw steel ring 14, is fixed on stator base 5 by bolt through screw by stator core group 2; Rotor core group 1 refers to and each permanent magnet is formed whole circle set of permanent magnets by the difference of radian size, and each whole circle permanent magnet is provided with fixed steelring 9, through screw, each whole circle permanent magnet is fixed on rotor base 6 by bolt; Connecting axle 3 and rotor base 6 are fixed by bolt in base back surface.
Further, stator core group 2 is at least 2 groups.
Further, rotor core group 1 is at least 3 groups.
Further, the outside of stator core group 21 is overlapped in the inner side of rotor core group 11, the outside of rotor core group 12 is overlapped in the inner side of stator core group 21, and the outside of stator core group 22 is overlapped in the inner side of rotor core group 12, and the outside of rotor core group 13 is overlapped in the inner side of stator core group 22.
The invention has the advantages that: first combined type efficiency motor adopts the compound design of high power density, and the magnetic field S pole that solenoid can be made to produce and N pole are all utilized effectively, and greatly can improve power output efficiency, with energy savings.Again adopt this physical structure to have effectively utilance to bulk, relative can size do less.Also the number of turns unshakable in one's determination can constantly be superposed as required, can scalability be large flexibly.
This motor, due to improvement physically, namely improves the utilance of self space, also makes power output efficiency be improved, otherwise also greatly can improve generating efficiency to economize on resources with the generator that this physical structure is made.
