Example

As shown in Figures 13 to 17, the difference between this embodiment and the first embodiment is that a plurality of permanent magnets are arranged in the mounting through hole 4 and are arranged relatively; four groups of permanent magnets are respectively arranged on the stator body 1 and the rotor body 1, and the four groups of permanent magnets are arranged relatively, and the magnetism between the permanent magnets on the rotor body 1 and the permanent magnets on the stator body 1 is arranged in any one of S-S and N-N ways; the arrangement of permanent magnets as shown in Figures 13 and 14, that is, the permanent magnets and the conductive coils 3 are arranged on the stator body 1 and the rotor body 1 in cooperation, wherein the conductive coils 3 on the stator body 1 and the rotor body 1 are changed from the original four as a group to three as a group, wherein the conductive coils 3 are arranged adjacently and relatively and are connected in series with each other; as shown in Figures 16 and 17, a permanent magnet is arranged in the mounting shell 2-1, that is, the conductive coils 3 and the permanent magnets mutually arranged on the stator body 1 and the rotor body 1 of the present technology will be superimposed again, and the magnetic field of the conductive coils 3 will be enhanced again, and the working efficiency of the motor will be improved again.

The triangle connection method is adopted here; as the magnetic field on the rotor body 1 increases, it helps to improve the work efficiency of the motor. Compared with the motor efficiency in the prior art, it will be improved, that is, inserting an iron core in the middle of the conductive coil 3 will enhance the magnetic field of the conductive coil 3, which will be weaker than the insertion magnetic field without an iron core in the prior art. Under the enhanced magnetic field of the conductive coil 3, the work efficiency of the motor will also be enhanced; Replace the conductive coil 3: When the conductive coil 3 inside the motor is damaged, the multimeter is used to detect and obtain the exact position of the damaged conductive coil 3. It is only necessary to remove the mounting shell 2-1 at the position of the rotor body 1 from the inside of the mounting through hole 4, and remove the conductive coil 3 wound on the mounting shell 2-1, and then wind the new conductive coil 3 on the mounting shell 2-1, and insert it into the mounting through hole 4 on the rotor body 1 to complete the replacement and installation of the conductive coil, which is convenient for the staff to replace. The mounting shell 2-1 here is insulated. Among them, the two leads of the conductive coil 3 are respectively led out from the two grooves 2-2, and the leads are connected to the power supply, so that the conductive coil 3 in each mounting through hole 4 is a changing magnetic field, and then the magnetic field of the single conductive coil 3 is electrically connected in series according to the A, B, and C series mode shown in Figure 12, where a is four series, and two leads are led out to connect to the power supply, b is four series, and two leads are led out to connect to the power supply, and c is four series, and two leads are led out to electrically connect to the power supply, that is, there are three driving magnetic fields on the rotor body 1, and a Hall sensor is used to detect the change of the magnetic field on the stator body, and cooperate with the motor controller to change its current input to the conductive coil 3 on the rotor body 1, and then change the magnetic field change on the rotor body 1 as the direction of the magnetic field of the stator body 1 changes to drive the rotor to rotate.
