In one embodiment of the stator and rotor core structure of the present invention, as shown in fig. 3 and 4, permanent magnet pole pairs are provided on the stator

And permanent magnet/excitation armature winding permanent magnet block assemblies which are in the same magnetic polarity with the air gap coupling surfaces on the rotor through air gaps to form a permanent magnet and electromagnetic continuous pulling/pushing transmission structure, wherein at least one pair (five pairs in the example) of permanent magnet magnetic pole pairs with permanent magnet attraction near force application channels and repulsion far force application channels (the permanent magnet pulling/pushing force application channels for short) with air gap coupling surfaces at two sides respectively in a magnetic strength gravity center inward-biased structure are arranged on a stator magnet yoke/body

The assembly and at least one pair (five pairs in the example) of electromagnet/excitation armature windings comprise one pair, two pairs or more than two pairs of electromagnet/excitation armature windings which are arranged side by side along the circumference/axial direction, and each pair of permanent magnet magnetic pole pairs

The air gap coupling surface is attracted into a near (tension) force applying channel by a permanent magnet (in this case, an N pole)

And permanent magnet (S pole in this case) repelling far (thrust) thrust channel

… … arranged along the air gap coupling circumference of stator body/magnetic yoke, and at least one pair of electromagnet/excitation arranged between two pairs of permanent magnet poles or/and at least one position of the change position of the pairs of permanent magnet polesAn armature winding; at least one permanent magnet block (in this example, twenty permanent magnet blocks) with the same magnetic polarity S on the air gap coupling surfaces are arranged on the rotor body along the circumference in a matched mode. The structure that the gravity center of the magnetic strength is deviated inwards means that the air gap coupling surface corresponding to the permanent magnet on the rotor is used as the reference surface of the magnetic field intensity measuring position of the stator permanent magnet magnetic pole pair, the magnetic field intensity of the permanent magnet pulling/pushing force channel at the two ends of the stator permanent magnet magnetic pole pair is enhanced from outside to inside by the magnetic strength gradient or/and gradually enhanced by the magnetic strength to form the structure that the gravity center of the magnetic strength is deviated inwards or inwards, that is, in the air gap coupling transmission process of the stator and the rotor, the permanent magnet in the gravity center of the magnetic strength is attracted into the force channel

The attraction tension of the S permanent magnets or permanent magnet groups with the same magnetic polarity on the air gap coupling surfaces of the rotor gradually increases from far to near and from outside to inside, and the permanent magnets are sequentially attracted from outside to inside to approach to drive the rotor to rotate clockwise to apply work and gradually approach to the magnetic pole change area

When the permanent magnet block is about to enter the magnetic pole changing area

At any moment, forward exciting current is sequentially supplied to the front corresponding electromagnet/excitation armature winding which is matched and arranged on the stator and is related to the electromagnet core/excitation armature winding, so that an electromagnetic N pole is generated on the air gap coupling surface of the iron core of the electromagnet/excitation armature winding, forming electromagnetic pull force on the permanent magnet blocks to overcome the resistance of magnetic pole change existing in the magnetic pole change area until the permanent magnet blocks rotate clockwise to align with the corresponding iron core/magnetic shoe positions, that is, the shortest magnetic flux path or the centering position of the magnetic coupling surface between the permanent magnet and the iron core/magnetic shoe, then the electromagnet/excitation armature winding is electrified with reverse excitation current to generate an electromagnetic S pole on the air gap coupling surface of the iron core/magnetic shoe, and forming electromagnetic thrust on the permanent magnet, continuously or uninterruptedly overcoming the magnetic pole change resistance existing in the magnetic pole change area until the permanent magnet rotates out of the magnetic pole change area clockwise.

And smoothly enters a permanent magnet S pole with eccentric magnetic strength gravity center to reject out of a far force application channel

Then, the reverse exciting current of the electromagnet/exciting armature winding is cut off; permanent magnet repulsion thrust boosting channel with magnetic strength and eccentric center of gravity

The repulsion thrust of the permanent magnet blocks or permanent magnet block groups with the same magnetic polarity S on the air gap coupling surfaces of the corresponding rotors is gradually reduced from near to far and from inside to outside, and the repulsion thrust of the permanent magnet blocks from inside to outside sequentially repels the permanent magnet blocks to far, so that the rotors are driven to continuously or uninterruptedly rotate clockwise to apply work until the permanent magnet blocks are pushed out of the force application channel where the permanent magnet S poles repel to far

In the process, the permanent magnet pole pairs are overcome due to existence

Magnetic pole change resistance and/or permanent magnet pole pair of magnetic pole change area

The controller obtains the alignment and centering information between the coupling surface of each permanent magnet with the same magnetic polarity S on the rotor and the coupling surface of the electromagnet core/excitation armature winding core magnetic shoe on the stator in real time through the position sensor, automatically controls the electromagnet/excitation armature winding to generate electromagnetic pulling force or electromagnetic pushing force, ensures that the electromagnetic pulling force/pushing force continuously or uninterruptedly pulls/pushes the corresponding permanent magnet and drives the rotor to continuously rotate clockwise, leads the permanent magnet with the same magnetic polarity S on the rotor to form forward pulling and backward pushing, and simultaneously or/and sequentially enters the next pair of permanent magnet pairs under the clamping or assisting of the superposition force of the electromagnet/excitation armature winding pulling/pushing rotor

The permanent magnet N pole with the magnetic strength and the eccentric center of gravity is attracted into the near forcing channel

By parity of reasoning, the permanent magnet and the electromagnetic attraction pulling force or/and the repulsion pushing force continuously drive the rotor to rotate in a clockwise circulating reciprocating manner and continuously do work, and power and energy are output.

The specific technical scheme of the invention is as follows:

a method for realizing permanent-magnet and electromagnetic continuous pull/push transmission structure is characterized by mainly comprising a permanent-magnet and electromagnetic continuous pull/push transmission stator-rotor structure coupled by an air-gap magnetic field, a rotor shaft, a bearing, a position sensor, a controller and other accessories matched with the controller, wherein in the permanent-magnet and electromagnetic continuous pull/push transmission stator-rotor structure coupled by the air-gap magnetic field, at least one pair of permanent-magnet magnetic pole pair subassemblies and at least one pair of permanent-magnet/excitation armature windings are arranged on a stator magnet yoke/body along the air-gap coupling circumference, permanent-magnet block subassemblies with same magnetic polarity are uniformly distributed on the rotor along the air-gap coupling circumference, and the permanent-magnet magnetic pole pair subassemblies

The air gap coupling surface is formed by respectively arranging permanent magnets with different magnetic polarities on two sides, and magnetic strength gradient enhancement or/and magnetic strength gradual enhancement from outside to inside and magnetic strength gravity center inward-biased structure, wherein the permanent magnets attract the near force application channel and repel the far force application channel, and the magnetic pole change area between the force application channels

Three parts are formed, permanent magnetic pole pair

One side of the air gap coupling surface is a permanent magnet attraction approach force application channel which attracts and pulls in the permanent magnet assembly air gap coupling surface in different magnetic ways and gradually enhances the pulling forceThe other side is a permanent magnet repulsion far-force-applying channel which has the same repulsion and push-out with the same magnetism on the air gap coupling surface of the permanent magnet block component and the gradually weakened thrust, and the air gap coupling surfaces of the permanent magnet pull/push-force-applying channels of the permanent magnet pole pair component are crossed in magnetic polarity and connected end to end, namely … …

The permanent magnet pushing/pulling force applied by the weak magnetic regions connected end to end of the assembly is insufficient, so that the rotor permanent magnet block assembly is ensured to be continuously or uninterruptedly pulled/pushed to rotate, and the rotor is driven to be cold-started or normally run.

The method for realizing the permanent magnet and electromagnetic continuous pulling/pushing transmission structure is characterized in that the permanent magnet assembly with the same magnetic polarity refers to that the polarity arrangement directions of all permanent magnets in the permanent magnet assembly are the same or consistent, namely either the N pole or the S pole of the magnetic pole are arranged towards the air gap coupling surface; the permanent magnet attraction tension boosting channel with the structure of magnetic strength gravity center deviating from the inner structure is pulled in from outside to inside with the permanent magnet groups with the same magnetic polarity coupled with corresponding air gaps, the permanent magnet attraction tension is gradually increased, and the permanent magnet blocks are attracted into the tension boosting channel until approaching the magnetic pole change area of the permanent magnet blocks

The generated magnetic pole changes the pull-push dead point resistance, so that the permanent magnet is continuously pulled/pushed out of the magnetic pole changing area by the electromagnetic force

The permanent magnets which smoothly enter the other side of the magnetic force gravity center and are in the same polarity repel the far forcing channel, so that the rotor is driven to continuously rotate forwards to apply work by electromagnetic cold start, connection or interruption, and then the permanent magnet repelling thrust forcing channel of the magnetic force gravity center structure and the corresponding coupled permanent magnet group are pushed out from the inside to the outside, the permanent magnet repelling thrust is gradually weakened from the strength to drive the rotor to continuously rotate forwards to apply work, and the permanent magnet blocks are smoothly pushed out of the permanent magnet repelling far forcing channel; meanwhile, because a weak magnetic section/magnetic force application interruption area is arranged between the permanent magnetic pole pair subassemblies or exists, the electromagnet/excitation armature winding is positioned and controlled in real time to generate repelling/attracting electromagnetic magnetic poles, electromagnetic pushing/pulling force is formed between the permanent magnetic blocks, the rotor is driven to rotate forwards to continuously apply work, the permanent magnetic blocks smoothly enter the permanent magnetic attraction of the structure with the magnetic strength gravity center biased inwards of the next pair of permanent magnetic pole pairs to approach the force application channel, and so on, the permanent magnetic and electromagnetic mixed magnetic attraction pulling force/magnetic repulsion pushing force in the stator and rotor transmission structure can drive the rotor to cold start clockwise or anticlockwise and continuously rotate to apply work, and power and energy are output;

(111) The dovetail air gap coupling surface is formed by N magnetic permanent magnets with different magnetic polarities at two sides, enhanced magnetic strength gradient from outside to inside and provided with a magnetic strength gravity center inward-biased structure, a near force application channel (113), an S magnetic permanent magnet repelling far force application channel (114) and a magnetic pole change area between the force application channels (113, 114)

(112) Three parts, i.e. dovetail permanent-magnet pole pairs

… … along the air gap coupling circumference of the stator body/magnetic yoke (110), the permanent magnets (115, 116) arranged between the two pairs of permanent magnet pole pairs are respectively in air gap coupling with the circumferential coupling surface of the permanent magnet block group (122) with the same magnetic polarity of the S pole on the rotor.

The working mechanism is as follows: the permanent magnet attraction introduction near boosting channel (113) with the structure of magnetic strength gravity center deviating from the inner structure and the permanent magnet group (122) with the same magnetic polarity of the S magnetic pole coupled with the corresponding air gap are drawn in from outside to inside, the permanent magnet attraction tension is gradually increased, and the attraction introduction is near or drawn into the boosting channel (113) until the magnetic pole changing area is approached

(112) Driving the rotor to rotate to do work; with the progress of the times, the controller obtains the change area of the magnetic pair magnetic poles of the permanent magnets on the rotor and the permanent magnets on the stator according to the position sensor (132)

(112) Corresponding, aligning or/and aligning real-time position information between the electromagnets, and timely/real-time control of the adaptive electromagnets (115, 116) and the corresponding permanent magnets (122) to be aligned before and after the alignment line so as to respectively generate electromagnetic attraction pulling force and electromagnetic repulsion pushing force to overcome the magnetic pole change area of the water magnet in the permanent magnet group due to the fact that the water magnet is positioned in the permanent magnet magnetic pole pair

(112) The generated magnetic pole changes the pull-push dead point resistance, and simultaneously or together with the rotation inertia, the permanent magnet blocks are continuously pulled/pushed out of the magnetic pole changing area by the electromagnetic force

(112) The permanent magnet repelling thrust force gradually weakens from inside to outside to drive the rotor to continuously rotate for doing work, and the permanent magnet blocks are smoothly pushed out of the permanent magnet repelling far channel (114); meanwhile, as the weak magnetic sections (117) are arranged at the head-to-tail connection positions of the pushing/pulling force application channels (114, 113) of the two pairs of permanent magnet magnetic pole pairs (111), the electromagnet is positioned and controlled in real time/in real time to form electromagnetic pushing/pulling force between the permanent magnet blocks corresponding to the electromagnet, the rotor is driven to rotate forwards to continuously do work, the permanent magnet blocks smoothly enter the permanent magnet attraction of the structure with the magnetic strength gravity center of the next pair of permanent magnet magnetic pole pairs (111) and are introduced into the near force application channel (113), and so on, the permanent magnet and electromagnetic mixed magnetic attraction pulling force/magnetic repulsion pushing force in the stator and rotor transmission structure can drive the rotor shaft (130) to cold start clockwise or anticlockwise and continuously rotate to do work. Further, the magnetic pole change region of the permanent magnetic pole pair (111)

(112) The ratio of the arc length of the magnetic pole changing area (112) to the arc length of the force applying channels (113, 114) on the two sides is extremely small, and the magnetic pole changing resistance of the magnetic pole changing area is relatively minimum, so that the total work doing amount of the permanent magnet pulling/pushing force continuous work doing of the magnetic pole changing area shows a non-conservative force work doing effect.
