Background
An electric Motor (Motor) is a device that converts electrical energy into mechanical energy. The electromagnetic power rotary torque is formed by utilizing an electrified coil (namely a stator winding) to generate a rotary magnetic field and acting on rotor pole teeth (such as a squirrel-cage closed aluminum frame). The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor and the rotating speed of rotor pole teeth are not kept at the same speed). The motor is mainly composed of stator and rotor teeth, and the direction of the forced movement of the electrified conducting wire in the magnetic field is related to the current direction and the direction of the magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to rotate the motor.
In order to generate a rotating magnetic field, the traditional motor enables windings in different phases to be electrified in turn to do work, not all coil windings do work in unit time, and the power density ratio and the efficiency are relatively low; the stator winding and the rotor winding are only opposite to each other in one magnetic stage, and the electromagnetic field energy of the other magnetic stage of the rotor winding, especially the inner magnetic pole of the rotor winding, is not well utilized, so that the efficiency of the motor is influenced to a certain extent.
In addition, in places where multiple power outputs are needed, multiple motors are generally needed to be installed, so that not only is space occupied, but also basic loss is generated when each motor works.

Wherein the rotor mechanism group 3 comprises two rotor mechanisms (3a, 3 b).
The rotor mechanism 3a and the rotor mechanism 3b are arranged in parallel with each other.
The rotor mechanism 3a includes a rotating shaft 31 and rotor teeth 32 mounted on the rotating shaft 31. The rotating shaft 31 passes through the central axis of the rotor pole teeth 32, and after the rotor pole teeth 32 are electrified, the output power of the motor is output through the rotating shaft 31.
The rotor mechanism 3b has the same structure as the rotor mechanism 3a, and will not be described in detail here.
The rotor means 3a and the rotor means 3b are located close enough to each other that a magnetic influence can be generated between adjacent rotor teeth 31.
Preferably, the distance between the rotor teeth 32 of the rotor mechanism 3a and the rotor mechanism 3b is 1cm to 7 cm.

The two ends of the rotating shaft 31 are respectively provided with a wiring mechanism 33.
the wiring mechanism 33 is cylindrical and is constituted by a plurality of wiring terminals 331 uniformly arranged along the peripheral wall on the side of the rotating shaft 31.
The terminals 331 are isolated from each other and are connected to one rotor winding, respectively.
Preferably, the connection mechanisms 33 correspond to the rotor windings on the rotor teeth 32, respectively, and the connection terminals 331 correspond to the rotor windings one-to-one, respectively.
The magnetic polarity of the rotor teeth 32 is adjusted and managed by the winding direction of the rotor windings and the phase or polarity of the current drawn by the connection mechanism 33.
The rotor mechanism 3a and the rotor mechanism 3b rotate in opposite directions.
The side of the rotor teeth 32 of the two rotor mechanisms (3a, 3b) which are close to each other forms a traction area a. In the attraction zone a, the rotor teeth 32 of the different rotor arrangements have a mutually attracting force.
the number of the rotor teeth 32 on the rotor mechanism 3a and the rotor mechanism 3b is the same, and the rotor teeth 32 on different rotor mechanisms correspond to each other in the working process.
The magnetic attraction between the pairs of rotor teeth 32 on the rotor mechanism 3a and the rotor mechanism 3b after crossing the center line of the two rotor mechanisms (3a, 3b) stops during the rotation.
Only when the connecting terminals 331 at both ends of the rotating shaft 31 are turned to the boundary, the plus-minus power supply can be turned on, and the two rotor mechanisms (3a, 3b) are attracted toward one side to rotate the two rotor mechanisms (3a, 3 b).
Preferably, the sides of the rotor teeth 32 of the two rotor arrangements (3a, 3B) facing away from each other form a repulsion zone B. In the repulsive force region B, the rotor teeth 32 of the two rotor means (3a, 3B) have a force of mutual repulsion.
Specifically, the magnetic polarities of the pair of rotor teeth closest to each other on the two rotor mechanisms (3a, 3b) are opposite to each other;

The pairs of rotor teeth 32 on different rotor mechanisms on the side near the repulsion zone B are magnetically identical.
preferably, the 3-5 pairs of rotor teeth 32 on different rotor mechanisms on the side near the attraction zone A are opposite in magnetic polarity.
In other embodiments, the pairs of rotor teeth 32 of the two rotor means (3a, 3b) that are remote from each other are not magnetically attracted to each other.
The stator-free multi-loop energy-saving motor adopting the technical scheme has the advantages that the plurality of rotor mechanisms are arranged in parallel through redesign, the adjacent rotor mechanisms are rotated in opposite directions by utilizing the magnetic attraction force exerted when paired rotor pole teeth on the adjacent rotor mechanisms are close to each other or the magnetic repulsion force exerted when the paired rotor pole teeth are far away from each other, and the output power of the motor is output through the rotating shaft. The stator-free multi-loop energy-saving motor has the advantages that the structure is extremely compact, the stator-free multi-loop energy-saving motor is very suitable for being applied to places needing multi-path power output, the loss of the motor in the working process is reduced, and the working efficiency of the motor is improved. More importantly, the stator-free multi-loop energy-saving motor also fully utilizes the rotation of the magnetic force boosting rotor mechanism between the adjacent rotor mechanisms, compared with the common two-phase and three-phase motors with the gaps between the stator and the rotor pole teeth, the efficiency is higher than 1 time, the power is higher, the energy can be saved by 15 to 35 percent, and the stator-free multi-loop energy-saving motor can be applied to the fields with important energy-saving efficiency such as a mobile new energy electric vehicle and the like.
Example 2
Fig. 6 schematically shows a stator-less multi-circuit energy-saving motor according to an embodiment of the present invention. As shown in the figure, the difference from embodiment 1 is that the magnetic directions of a plurality of rotor teeth 32 on the same rotor mechanism in the range of the attraction force region a and the repulsion force region B are the same, i.e. the magnetic polarities outside the rotor teeth 32 are both S poles or both N poles.
Of course, in other embodiments, there may be a case where the magnetic directions of the plurality of rotor teeth 32 on the same rotor mechanism are spaced from each other in the range of the attraction force region a and the repulsion force region B, that is, the magnetic polarities outside the rotor teeth 32 are alternately arranged by S poles and N poles.
Example 3
Fig. 7 schematically shows a stator-less multi-circuit energy-saving motor according to an embodiment of the present invention. As shown in the figure, the difference from embodiment 1 is that the rotor mechanism group 3 includes a rotor mechanism 3a and a rotor mechanism 3b, the number of rotor teeth on the rotor mechanism 3a and the rotor mechanism 3b is the same, and the rotor teeth on the different rotor mechanisms correspond to each other one by one during the operation. The connection means 33 correspond to the rotor cores on the rotor teeth and are connected to a conductive carbon brush 34. The rotor mechanism 3a and the rotor mechanism 3b are provided with two sets of rotor pole teeth, respectively.
The current loop of the stator-free multi-loop energy-saving motor is as follows: the conductive carbon brush 34 is in contact with a connection terminal of the connection mechanism 33 at one end of the rotor mechanism 3a for conduction, the rotor core 321a connected with the connection terminal is electrified to generate magnetic force, current passes through the rotor core 321b and is electrified to generate magnetic force, the current passes through the rotor core 321b and reaches the connection mechanism 33 at one end of the rotor mechanism 3a, then passes through two conductive carbon brushes 34 connected in series with each other and is in contact with one connection terminal of the connection mechanism 33 at one end of the rotor mechanism 3b for conduction, the rotor core 321c connected with the connection terminal is electrified to generate magnetic force, the current passes through the rotor core 321d and is electrified to generate magnetic force, and the current passes through the rotor core 321d and reaches the connection mechanism 33 at one end of the rotor mechanism 3b and then flows out.
The working process of the stator-free multi-loop energy-saving motor follows the operation principle of the carbon brush motor, namely, in the operation process, only the rotor core where the wiring terminal in contact with the conductive carbon brush 34 is positioned is electrified to form a loop. And in the operation process, the process of the current loop is circularly operated, so that the motor generates the rotation kinetic energy and outputs the rotation kinetic energy through the rotating shaft.
In this embodiment, a simple connection method is adopted, i.e., brushes covering a plurality of connection terminals are arranged in the rotor mechanism attraction area a and the repulsion area B, and the directions of rotor windings of the rotor pole teeth are the same.
When the rotor mechanism works, 4-8 continuous wiring terminals of the same rotor mechanism are simultaneously communicated with one electric brush, and therefore the magnetic directions of a plurality of rotor pole teeth on the same rotor mechanism are the same.
What has been described above are only some embodiments of the present invention that exemplify a rotor mechanism group composed of two rotor mechanisms. On the basis of understanding the technical solutions, a person skilled in the art may set a rotor mechanism group consisting of three or more rotor mechanisms as required.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
