Permanent magnetism power-increasing device stator poles assembly duty has two kinds: one is when " positive flux field " state, electric The moving field in magnetic field is superposed to the enhancing magnetic field that direction is consistent with the magnetostatic field of permanent magnetic field, acts on permanent magnetism and turns Subelement；It is two when " counter magnetic field " state, electromagnetic field individually to p-m rotor unit effect, and with Time stop that the effect of permanent magnetism magnetostatic field gets involved, the work of transformation of its two states be " two circulation ", collection Magnet Core 5 plays Flux switch effect.

Further, concrete, the DC of the present invention adds energy motor, is by casing, is fixed on machine The p-m rotor that permanent magnetism power-increasing device stator poles assembly in shell is connected with bearing with drive end bearing bracket, rear end cap Unit and exchange system assembly are constituted；This motor have employed ternary structural from energy hierarchical configuration, ginseng See Fig. 3～Fig. 4, the energy ratio of up of three layers interior, domestic and abroad be: permanent magnetic/electromagnetic energy=2:1；

As shown in Fig. 5,6,8,9, the bearing 2 at motor shaft 1 two ends and drive end bearing bracket 15, rear end cap 10, it is connected to casing two ends by screw 14 respectively.Stator permanent magnet is radial magnetizing, by polylith (individual) It is distributed with magnetism-collected structure side by side, plays outer layer permanent magnet sources effect, winding 7 and collection magnetic core 5 and play middle level The commutation of electromagnet source and permanent magnetism add the effect of energy, and therefore permanent magnetism power-increasing device is to have middle level and outer layer energy body Unit；Rotor permanent magnet is radial magnetizing, polylith form four magnetic poles, the pole of adjacent two magnetic poles Property contrary, p-m rotor unit constitutes the permanent magnet sources of internal layer；Interior, the outer tri-layer energy source distribution ratio of neutralization Rate is: permanent magnetic/electromagnetic energy=2:1；

Above-mentioned permanent magnetism power-increasing device stator poles assembly is distributed in casing respectively by 6 unit, and it collects magnetic core 5 make with stalloy, and its shape can be " work " or " T " font as required, and small end inner layer is corresponding P-m rotor unit, intermediate portion cross-section is less, and winding 7 embeds wherein, and the area of large end face is maximum, Being close to pole-face in tile stator permanent magnet 6, the magnetizing direction of all stator permanent magnets is radially, ginseng See N, S mark in figure, by same magnetic direction 4 pieces or polylith arranged side by side, see Fig. 4～6, this poly-magnetic Arrangement adds the magnetostatic potential energy of permanent magnetism, and is gathered by the big end collection of collection magnetic core 5, then focuses on stage casing Then it is transmitted to small end and acts on p-m rotor finite element rotation；

It should be noted that the polylith stator permanent magnet 6 in above-mentioned six groups of permanent magnetism power-increasing device stator poles unit, Its magnetic direction installed has two kinds of structures: one, often the stator in group permanent magnetism power-increasing device stator poles unit Permanent magnet 6 is the most uniform, magnetic direction phase between two groups of the most adjacent permanent magnetism power-increasing device stator poles unit Counter being spaced, magnetic pole presses N, S, N, S, N, S；Its two, often group permanent magnetism power-increasing device stator poles list The stator permanent magnet 6 of unit is the most uniform, magnetic between two groups of the most adjacent permanent magnetism power-increasing device stator poles unit Field direction is same to be arranged to axle center, and magnetic pole presses N, N, N, N, N, N, and both the above structure is the most not Affect permanent magnetism and add the function of energy.Owing to the number of magnetic poles of p-m rotor unit and the angle of rotation are different, So the controlled magnetic direction of permanent magnetism power-increasing device stator poles assembly is the most different, therefore on circumferential position together with Time produce magnetic attraction and repulsive force and drive p-m rotor unit rotational.

Above-mentioned DC adds energy motor operation principle as shown in Fig. 8～9: when the p-m rotor of motor is in just 0 degree of position of beginning is when starting working, and three groups of commutating brushes 20 are energized with three-phase windings the most simultaneously, and electric current turns Changing latus rectum is: DC source → conducting brush → conducting ring → commutation semi-ring → commutating brush → three-phase windings → collection magnetic core → permanent magnetism adds energy → p-m rotor → mechanical energy output；Due to commutation semi-ring and three groups of commutations Brush location when circular contact is different, and the sense of current causing three-phase windings to control is also the most different, So the magnetic direction of collection magnetic core is different, the produced suction to p-m rotor, repulsion design institute just Regulation, they drive the two poles of the earth rotor to move in the direction of the clock respectively, in the angle of 0 degree～60 degree Permanent magnetism power-increasing device is under " positive flux field " state, permanent magnetism and electromagnetism superposition, and couples magnetic flux increases, and collects magnetic P-m rotor magnetic force is strengthened by iron core 5, plays permanent magnetism and adds and can act on；Otherwise at permanent magnetism power-increasing device Under " counter magnetic field " state, internal layer p-m rotor is only played the effect of electromagnetic force by collection magnetic core 5, simultaneously The effect of stator permanent magnet is blocked in outer layer, and " positive and negative " magnetic field of this two circulations jointly acts on and turning Son rotates；When going to 60 degree, commutator assembly sequentially enters next phase place, and rotor continues to rotate, defeated Go out power, such iterative cycles, motor continuous firing.

Machinery (the having brush) DC that controls adds and can be mainly characterized by energy-conservation, low cost, is suitable for by motor In driving class motor.

DC disclosed by the invention adds energy motor, mainly fixed by rotor permanent magnet and permanent magnetism power-increasing device Three level (ternary) energy resource structure compositions of sub-pole assembly, when p-m rotor starts to rotate, diverter Power to permanent magnetism power-increasing device, collect magnetic core winding excitation, produce electromagnetism and permanent magnetic overlapped couples magnetic flux, Jointly acting on p-m rotor to rotate, synthesis is converted to mechanical energy, in this electromagnetic energy transformation process Complete permanent magnetism simultaneously and add energy, the utilization rate of permanent magnetism energy is greatly improved；DC adds can motor knot Structure is ternary, and principle is two circulations, and the technology adding energy with permanent magnetism utilizes permanent magnetism energy, and feature is energy-efficient, Mechanism is relatively easy, is a kind of New-type electric machine.

The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.One's own profession Skilled person will appreciate that of industry, the present invention is not restricted to the described embodiments, above-described embodiment and explanation The principle that the present invention is simply described described in book, without departing from the spirit and scope of the present invention, The present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention model In enclosing.Claimed scope is defined by appending claims and equivalent thereof.
