In this way, on the inner wall 110 of the lower half gun shell 109, a motor stator a / a air gap edge 118 is formed between the stator a / a inner diameter surface 78 of the A, B deformed rectangular frame Helmholtz coil stator 75 and the circular diameter surface of the permanent magnet cylindrical rotor outer diameter 8a, and a motor stator b / b side air gap 119 is formed between the stator b / b side inner diameter surface 85 and the circular diameter surface of the permanent magnet cylindrical rotor outer diameter 8a. In addition, a Hall coil driver 117 is placed on the lower half fixed opening 113 of the Hall coil driver between the middle of the stator a / a side combined layer 80 and the lower half gun shell inner wall 110 on the stator a / a side outer diameter surface 82, so that the dynamic magnetic field tangent point circular trajectory 12 generated when the permanent magnetic cylindrical rotor 8 rotates passes through the intersection of the Hall coil driver 117 circle (the Hall coil driver 117 device uses a highly integrated bipolar CMOS semiconductor process to integrate the Hall element and the motor control circuit on a single chip, and basically all the circuits are built into the package of the device without the need for other external auxiliary devices, providing a very reliable motor drive solution). Thus, a permanent magnetic cylindrical rotor deformed rectangular frame Helmholtz coil stator magnetoelectric motor is combined.

[0046] like( Fig.21 , Fig. 22), the upper gun shell 127 is covered on the assembled lower gun shell 109. And through the four fixing screw holes 135, 136, 137, 138 on the upper gun shell 127 and the four fixing nut holes 139, 140, 141, 142 on the lower gun shell 109, four gun shell upper and lower gun shell fixing screws 143, 144, 145, 146 are respectively inserted into the four fixing screw holes of the upper gun shell 127 and the four fixing nut holes of the half gun shell 109 and tightened (not shown in the drawings). The lower half gun case left bearing lower semicircular seat 112 at the middle center of the lower half gun case head semicircular end 111 in the lower half gun case inner wall 110 and the upper half gun case left bearing semicircular seat 130 at the middle center of the upper half gun case head semicircular end 129 in the upper half gun case inner wall 128 form a full-circle bearing seat, and firmly fix the left bearing 2. The lower half gun case right bearing lower semicircular seat 115 at the middle center of the lower half gun case right bearing semicircular seat fixing plate 114 on the lower half gun case inner wall 110 and the upper half gun case right bearing upper semicircular seat 133 at the middle center of the upper half gun case right bearing semicircular seat upper fixing plate 132 on the upper half gun case inner wall 128 form a full-circle bearing seat, and firmly fix the right bearing 9. The left bearing 2 and the right bearing 9 (described above) are used to support the steel needle shaft end 1c of the steel needle 1 of the permanent magnetic cylindrical rotor 8, so that the permanent magnetic cylindrical rotor 8 and the steel needle 1 rotate at high speed and smoothly. At the same time, the B deformed rectangular frame coil left semicircular arc end outer diameter surface 59, the B deformed rectangular frame coil a side outer diameter surface 47, the B deformed rectangular frame coil b side outer diameter surface 52, and the B deformed rectangular frame coil right semicircular arc end outer diameter surface 67 of the A, B deformed rectangular frame Helmholtz coil stator 75 are respectively fixed on the twisting gun upper half gun shell inner wall 128 of the upper half gun shell 127 as the upper half gun shell 127 and the twisting gun lower half gun shell 109 are closed. Thus, a kind of electric textile cleaning twisting gun driven by a micro brushless motor is combined.

[0047] like( Fig. 20 , Fig.21) as shown: the power switch 122, the lithium battery 124 and the lithium battery charging socket 125 installed on the inner wall 110 of the lower half gun shell 109 of the lower half gun shell 109 by the Hall coil driver 117 through the driver lead 120 and the stator lead 121 form a lithium battery, a power switch and a lithium battery charging circuit of an electric textile cleaning twist gun driven by a micro brushless motor. The Hall coil driver 117 can be a US79KUA advanced fan control integrated circuit chip or a domestic CT277 fan control integrated circuit chip, which is suitable for driving the 3v to 12v double-winding permanent magnetic cylindrical rotor deformed rectangular frame Helmholtz coil stator magnetoelectric motor of the electric textile cleaning twist gun driven by a micro brushless motor of the utility model. It does not require external electrical devices and has a stall protection function. When the integrated circuit finds that the electric textile cleaning twist gun driven by the micro brushless motor is stalled for 1s, it will turn off the motor for 5s. Then, the integrated circuit will restart the motor for 1s. This procedure will continue to start and stall several times. This feature prevents the motor and circuit from overheating. The motor can rotate stably and at high speed. In addition, the Hall coil driver 117 can also use the domestic JM477 fan control integrated circuit chip, whose power MOSFET bridge drive output provides bidirectional current to a group of coils of the motor, improves the utilization rate of the motor winding, makes the motor smaller and more efficient. When the power switch 122 is turned on, when the permanent magnetic cylindrical rotor 8 rotates, the two tangent points p and q formed between the two opposite magnetic lines of force generated by the two opposite magnetic poles of the hollow cylindrical permanent magnet 7 of the permanent magnetic cylindrical rotor 8, and the dynamic opposite magnetic tangent point circular trajectory 12 formed when the permanent magnetic cylindrical rotor 8 rotates make the Hall coil driver 117 within the coverage range of the magnetic lines of force when the dynamic opposite magnetic tangent point circular trajectory 12 is within the coverage range of the magnetic lines of force. Since the permanent magnetic cylindrical rotor 8 rotates a commutation cycle (360 electrical degrees), the Hall coil driver 117 can detect the positions of the two opposite magnetic poles of the permanent magnetic cylindrical rotor 8. The Hall coil driver 117 is made to divide a commutation cycle (360 electrical degrees) into two equal states. The Hall coil driver 117 detects that the magnetic pole polarity signal output by the permanent magnetic cylindrical rotor 8 is a 360 electrical degree polarity output signal. And the position signal of the permanent magnetic cylindrical rotor 8 detected by the Hall coil driver 117 is in the Hall coil driver 117 chip. The processed magnetic pole polarity signal output by the detected permanent magnetic cylindrical rotor 8 is a 360 electrical degree polarity output signal to the power drive circuit, and the 360 ​​electrical degree polarity voltage amplified by the power drive circuit and the electronic commutator is sent to the coil windings of the A and B deformed rectangular frame Helmholtz coil stator 75. The magnetic field generated by the stator windings of the A and B deformed rectangular frame Helmholtz coil stators 75 and the permanent magnetic field generated by the rotating permanent magnetic cylindrical rotor 8 are always maintained at an electrical angle of (90) rad in space, because the principle of the "Helmholtz coil structure" is adopted.The A deformed rectangular frame coil 13 and the B deformed rectangular frame coil 43 are deformed rectangular Helmholtz coils, and the A deformed rectangular frame coil a side combination side 18 and the A deformed rectangular frame coil b side combination 23 of the A deformed rectangular frame coil 13 are respectively matched and fixed with the B deformed rectangular frame coil a side combination surface 48 and the B deformed rectangular frame coil b side combination surface 53 of the B deformed rectangular frame coil 43, and are combined into the A and B deformed rectangular frame Helmholtz coil stators 75. The vertical distance between the A deformed rectangular frame coil a side combination surface 18, the A deformed rectangular frame coil b side combination surface 23 and the B deformed rectangular frame coil a side combination surface 48 and the B deformed rectangular frame coil b side combination surface 53, that is, between the two deformed rectangular coil planes is zero, or less than the width of the rectangular coil. When the two deformed rectangular Helmholtz coils are passed with current in the same direction, the magnetic field is superimposed and enhanced, and an approximately uniform magnetic field is formed in a certain area. A uniform magnetic field of a certain intensity is uniformly generated. The magnetic field distribution between the two coils is based on the principle of numerical simulation of MATLAB. The characteristics of the rectangular coil are: large uniform area and wide space. At the same time, since the A and B deformed rectangular frame Helmholtz coil stators 75 adopt a coreless motor structure, there is no magnetic pulling force between the A and B deformed rectangular frame Helmholtz coil stators 75 and the permanent magnetic cylindrical rotor 8. It is in a free state before power is turned on, so that the motor can be started smoothly. During installation, the axial magnetic lines of the A and B deformed rectangular frame Helmholtz coil stators 75 and the permanent magnetic cylindrical rotor 8 are deviated from each other. Therefore, the permanent magnetic cylindrical rotor deformed rectangular frame Helmholtz coil stator magnetoelectric motor transmission device of the present invention does not have a "starting dead point", so that the current of the A and B deformed rectangular frame Helmholtz coil stators 75 and the permanent magnetic field of the permanent magnetic cylindrical rotor 8 interact to produce the maximum electromagnetic torque, and the "permanent magnetic cylindrical rotor deformed rectangular frame Helmholtz coil stator magnetoelectric motor" driving the twist gun is continuously running at high speed. Thereby, the steel needle 1 is caused to run at high speed.

[0048] like( Figure 3 , Fig. 20 , ), the material of the hollow cylindrical permanent magnet 7 of the permanent magnetic cylindrical rotor 8 is selected from one of samarium cobalt, ferrite or neodymium iron boron permanent magnet materials.

[0049] like( Fig. 20 , Fig.21 , Fig. 22 ), the Hall coil driver 117 of the permanent magnet cylindrical rotor deformed rectangular frame Helmholtz coil stator magnetoelectric motor adopts US79KUA, US72 and US73 chips. At the same time, domestic CT277, JM477 fan control integrated circuit chips and chips of the same performance series can be used.

[0050] like( Fig.14 , Fig.15 , Fig.16 , Fig.17 ), the A and B permanent magnetic cylindrical rotors are deformed rectangular frame Helmholtz coil stators, using double winding coils or single winding coils

[0052] like( Figure 1 , Figure 2 ) as shown in the figure, the steel needle is composed of a steel needle tip as the steel needle head end, a steel needle body end as the steel needle middle end, and a steel needle shaft end as the steel needle rear end, forming an integrated steel needle.

[0053] like( Figure 1 , Figure 2 ) as shown, the rotor round tube core 5, the rotor round tube core outer diameter 5b, 5c-the left end 5c of the rotor round tube core, the rotor round tube core hollow cylindrical permanent magnet fixed end 5d, the fixed end outer diameter 5e, 5f-the rotor round tube core tail right end 5f constitute an integrated rotor round tube core 5, and the rotor round tube core 5 is sleeved and fixedly connected to the steel needle 1 to play a role in protecting the steel needle 1.
