Its rotor is made into the form of flange or cylinder body, and the stator is made up in the form of rectangular body. Said invented acyclic direct-current machine is strong in rigidity, can implement brushless structure, and can save energy and material, and easy to maintain, etc..
Description
The present invention relates to the motor or technical field of generators aperiodic under the IC table H02K31/00, particularly a kind of one pole absence of commutator direct current machine.
General main rotor, the stator two parts of comprising of at present general motor, rotor is made of rotating shaft, iron core and winding thereof, slip ring or commutator etc.But adopt the noise of motor of commutator bigger, the mutual transfer ratio of mechanical energy and electric energy is not high, and the power output in the unit volume is little.The Chinese patent communique disclosed " a kind of one pole DC and AC universal electric machine " on January 17th, 1996, and (application number 93108129) its structure as shown in Figure 9, this patent application has tentatively realized absence of commutator, its technical scheme mainly is: rotor core is the round cup that high permeability material is made, rotor coil is evenly distributed on the iron core circumference, its one side is distributed in the teeth groove, and another side then is arranged in the through hole.Because ferro-magnetic shield effect, the magnetic flux density in the through hole are zero.Thereby the carrying object in the through hole is not subjected to the effect of electromagnetic force, makes rotor only be distributed in the ampere moment of the coil in the teeth groove and rotates.It is just for realizing that the direct current machine absence of commutator provides the technology possibility like this.But there is following defective in this patent application:
1. from the stator structure shown in Fig. 9, be not difficult to find out, because what it had a unknown element 22 exists (this is the inventive point of this application just) no matter adopt axially or radially the one pole permanent magnet of excitation substitutes its normal loop 15, the capital makes the magnetic line of force walk around the tubular air gap and short circuit, therefore, when no matter the described motor of this patent application still makes rotor by magnet exciting coil by armature winding, all need to introduce (or drawing) electric current by brush, thereby this patent application can not make motor realize non-brushing completely, therefore will limit direct current machine and apply more widely.
2. its magnetic pole of the stator can only adopt high permeability material to make a pair of coaxial circles cylinder magnetic pole, constitute the inter-air space of a tubulose, this inter-air space one end is sealed by stator yoke, the other end then opens wide, the cup-shaped rotor places this inter-air space, stressed member in the rotor can only have an end to be installed on the axle, and the air gap of this spline structure is very unfavorable for the torsional rigidity that improves rotor.
The object of the present invention is to provide a kind of rotor that can make to have sufficiently high intensity, the low-frequency ac swing motor that can make rotation (or linear) direct current machine or armature line group power frequency be lower than 5HZ is again realized non-brushing, this motor has two air gaps at least, and its rotor can have multiple planform.
The object of the present invention is achieved like this:
The present invention is made up of stator, rotor, armature coil etc., its armature coil is located on the supporting core body 3, supporting core body 3 usefulness permeability magnetic materials are made, evenly be provided with groove 19 on its side, a limit of the unit coil 2 of armature coil is the groove 19 that the 2a limit places supporting core body 3, the projection and stator (or rotor) yoke of supporting core body 3 fit tightly, and magnetic screen is carried out on the unit coil 2 and the 2a limit that are opposite to jointly in the groove 19.Another 2b limit of unit coil 2 is in commentaries on classics (moving) and the common air-gap field 7 that forms of stator, and supporting core body 3 is installed on stator or the rotor; Rotor is cylinder or flange-like body, and mover is a cuboid; Air-gap field 7 is produced by the single or multiple magnetic sources that are contained in stator and the rotor.
The present invention has significant good effect:
1. the present invention has two above air gaps, can all not be sleeved on magnetic conductor and the axle by the overslaugh permanent magnet, so rotor is cylinder or flange-like body, the rectangular body of mover, rigidity height not only, and realized non-brushing, do not need commutator and brush, improved the mutual conversion efficiency of electromechanics and electric energy, and do not have AC noise, speed adjustable range is big, and the power output in the unit volume is big.
2. applied range.Application number can only be made torque motor for the motor that 93108129 patent application provides, because the supporting core body 3 of setting of the present invention can be installed on stator component or the rotor part, therefore motor provided by the invention not only can be made torque motor, and the generator that can make the drive motors of general service and special purpose or not limited by voltage height, size of current, have better speed governing and energy feedback characteristic.
