Summary of the invention
The present invention is intended to solve the problems such as heat that can produce iron loss and be harmful in existing DC motor structure complexity and the work, try hard to reduce cost, reduce loss, raise the efficiency, increase the service life, can also to this direct current machine (using magnetic suspension bearing) through simply the sealing after as energy storage motor (device).
The present invention realizes by following technical scheme.
The present invention is made up of stator, rotor and bearing, as shown in Figure 1 and Figure 2.
Admittedly overlap the disc permanent magnet of an axial charging at the every end of the round ring magnet of radial magnetizing, the U-loop slot field that described three permanent magnets surround is a unipolarity magnetic field; Make a U-loop groove unipolarity magnetic field again by preceding method, but its polarity is with previous opposite, the permanent magnet outer surface of two U-loop slot fields is linked up with disc and the combination of annular magnetic conductor, the permanent magnet of two U-loop slot fields is a heteropolarity with the face that magnetic conductor pastes mutually, thereby the magnetic line of force is connected, shown in dotted line among Fig. 1 Fig. 2; The cylindrical of the interior circle of magnetic conduction annulus and magnetic conduction disk and non magnetic annulus or non magnetic axle connects, connect the non magnetic disk that has mesopore at non magnetic annulus or non magnetic axle two ends, non magnetic disk connects with non magnetic annulus, but not magnetic disk connects by bearing with non magnetic axle, the mesopore of non magnetic disk connects with the cylindrical of bearing outer ring, and the interior circle of bearing inner race connects with the cylindrical of non magnetic axle; Above-described magnet assembly, magnetic and non magnetic connector constitute rotor of the present invention.
The non magnetic lead of strip winding insulating covering is made armature coil on non magnetic insulation annulus, armature coil is fixed it with non magnetic insulation annulus, the interior circle of non magnetic insulation annulus and another non magnetic insulation annulus or the cylindrical of non magnetic insulation axle connect, and have just constituted stator of the present invention.
The major part of armature coil both ends of the surface and cylindrical or interior circle are inserted in the rotor U-loop slot field, and the wall of the U-loop groove that surrounds with permanent magnet leaves a gap; The end face of the non magnetic insulation annulus of holding armature coil connects with non magnetic disk inner face or joins with the inner face of bearing inner race, with the mesopore interference fit of the outer ring of bearing and non magnetic disk and connect; And between the interior circle of rotor cylindrical or the corresponding stator of interior circle or the cylindrical gap is arranged, and between the inner face of rotor outer face or the corresponding stator of inner face or the outer face gap is arranged; The input of armature coil, output are guided to the outside of motor with the lead connection of tape insulation foreskin, and connect positive pole, the negative pole of power supply respectively, require to make the circulation direction of electric current in the armature coil cross section of the left and right sides opposite.
The bearing that connects or get in touch described stator and rotor is general mechanical bearing or magnetic suspension bearing.
Described armature coil equates with the set of permanent magnets group number that surrounds the U-loop slot field, according to actual conditions, can be designed to some groups, but minimum be two groups.
The present invention is as DC motor, its operation principle is: electromagnetism discloses, electrical conductor in the magnetic field can be subjected to active force, the size of active force is calculated by relational expression F=BIL, wherein B represents magnetic flux density, and I represents the current strength in the conductor, and L represents conductor the overall length dimension in magnetic field vertical with the magnetic line of force in magnetic field, to the wire-wound armature coil, L equals the armature coil number of turn and every circle average perimeter is long-pending; The direction of active force is judged according to left hand rule, promptly stretch out left hand, make thumb four refer to vertically in same palm plane, allow the N utmost point of the palm of the hand over against magnetic field with all the other, four sensings are consistent with the sense of current in the conductor, and at this moment thumb just indicates the force direction that is subjected to of conductor.In the present invention, show as Fig. 1, if the direct current of feeding for left armature coil sees it is clockwise on the top of armature coil section, and see to be exactly anticlockwise in the bottom, simultaneously, the onesize direct current of feeding for right armature coil sees it is anticlockwise on the top of armature coil section, and see to be exactly clockwise in the bottom, determine easily with left hand rule, two armature coil the first half force directions that every limit is subjected in magnetic field all leave the beholder and go, promptly vertical the sensing in the paper, and two armature coil the latter half force directions that every limit is subjected in magnetic field promptly vertically point to outside the paper all towards the beholder, like this, two armature coils produce the torque in the same way of relative rotor simultaneously, but armature coil is fixed, so rotor will rotate relative to armature coil.If change two senses of current in the armature coil simultaneously, the rotor rotation direction just changes.Described motor, in case bring up, B, L are relative definite value just, obviously, the size that only changes I just can change the rotating speed of rotor, and the size of change I is the technology that realizes easily.
After when described rotor operation, cutting off the electricity supply, rotor has inertia motion, the magnetic field of the induced current in the armature coil and rotor permanent magnetic field interact so, it is moving to hinder rotor rotation, as long as thereby reduce current strength in the armature coil, not only reduced power, and produced braking force simultaneously, realize brake deceleration, so armature coil can auxiliary brake.Thus, power supply can be designed and produced and to become to have two-way adjustable function---can power to armature coil, can reclaim induction electric energy from armature coil again.
The present invention is as DC generator, operation principle is identical with existing DC generator, follow electromagnetic induction principle, promptly, rotates rotor when being driven by exterior power, armature coil is done the motion of cutting rotor magnetic field magnetic line with respect to rotor, thereby produces induced electromotive force in armature coil, and its direction is judged (not giving unnecessary details) here with the right-hand rule, if the armature coil external load, formation induced current then is in closed circuit.The present invention uses as DC generator, if have only two armature coils, current opposite in direction in two armature coils, if two armature coils around to identical, respectively one input and another output are joined, thereby form two line ends, just be equivalent to the positive pole and the negative pole of power supply; If a plurality of armature coils are arranged, its connection is similar, can join addition behind this coil and increases as long as guarantee that the electric current of each armature coil flows out.
Isolate a gap in the periphery of described direct current machine (bearing magnetic suspension bearing) and make non magnetic closure, its inwall connects with the stator of motor, punch thereon the conductor wire of armature coil is drawn, and the space sealed, to be evacuated in the non magnetic closure then, become energy storage motor (being equivalent to energy accumulation device for fly wheel) like this.When powering to motor, described motor serves as DC motor, can make the rotation of its rotor high-speed and capacitation, and when the conduction line end external load of armature coil, described motor serves as the outside energy supply of DC generator, and in the energy storage phase, the conduction line end of armature coil is unsettled.
The above armature coil can also be made into whole with non-magnetic conductive material, removes non magnetic insulation annulus.
Compare with existing direct current machine, the present invention has following advantage:
1, absence of commutator, brushless, the iron core that no silicon steel sheet builds up, so simple in structure, cost is low;
2, eddy current loss in the motor and magnetic hysteresis loss, it is iron loss, only occur in motor shutdown process or the speed regulation process, (motor leads to steady direct current as if motor stabilizing work, generator input torque and rotating speed are constant) time, being in the armature coil in the stationary magnetic field is steady direct current, so there is not iron loss, energy-conservation, efficient is high;
3, because there is not iron loss during the work of brushless, motor stabilizing, thus can the long time of continuous operation, and long service life;
4, if described motor uses magnetic suspension bearing, and described motor brushless, absence of commutator, rotor rotate in a vacuum, thereby there is not a mechanical friction energy loss, and because described advantage 2, so described motor make energy storage device, more superior than devices such as existing flywheel energy storage, inductance coil energy storage, batteries to store energy, compressed-air energy storages.
