[0027] By arranging at least two winding modules 300 around the rotor 200, the winding modules 300 can generate a magnetic field to drive the rotor 200 to rotate when energized. The fixing structure 400 is detachably connected to the base 100, the rotor 200 and the winding modules 300 to fix the rotor 200 and the winding modules 300 on the base 100. Since the winding modules 300 are independent of each other, the assembly and disassembly operations are convenient. In addition, when one of the winding modules 300 fails or is damaged, it can be replaced separately for easy maintenance.

[0028] Reference Figures 1 to 3 In some embodiments of the present invention, the winding module 300 includes a winding seat 310, a winding 320 and a protective member 330. The winding seat 310 is provided with a winding portion, the winding 320 is wound on the winding portion to form a coil, and the protective member 330 is detachably connected to the winding seat 310 to cover part or all of the coil.

[0029] The winding 320 is wound on the winding part to form a coil, and when the coil is energized, a magnetic field that drives the rotor 200 can be generated. In addition, after the winding 320 is wound into a coil, the coil is shielded by the protective member 330, which can protect the coil from collision with external objects and improve reliability. When the coil fails or is damaged, the protective member 330 is separated from the winding seat 310, the problematic coil is removed, and the winding 320 is used to rewind it, which is convenient for maintenance operations.

[0030] The winding 320 may be an enameled wire or other commonly used wire for winding a coil. The protective member 330 may be an embodiment including a plurality of bolts, nuts and protective sleeves. The winding seat 310 is provided with a through hole, the bolt passes through the through hole, the protective sleeve is sleeved on the bolt, and the nut is threadedly connected with the bolt to limit the separation of the protective sleeve and the bolt, and fix the bolt on the winding seat 310. The protective member 330 may also be an embodiment including a plurality of clamping blocks. The winding seat 310 is provided with a clamping port matching the clamping block, and the clamping block is clamped with the clamping port to protect the coil.

[0031] refer to Figures 1 to 3 In some embodiments of the present invention, the winding module 300 further includes a magnetic core, and the winding seat 310 is provided with an insertion channel 311 extending into the coil surrounding space, and the magnetic core can be inserted into the insertion channel 311 .

[0032] Generally, windings are provided with magnetic cores that match the coils to enhance the magnetic induction intensity generated by the coils. By providing an insertion channel 311 on the winding seat 310, the magnetism can be inserted into the central surrounding space of the coil in a plug-in manner, the magnetic core is easy to assemble, and the magnetic cores of different materials can be quickly replaced according to the use requirements, making it more convenient to use. In some embodiments, the magnetic core can be fixedly connected to the winding seat 310 to form a winding part, that is, the magnetic core is fixedly connected to the winding seat 310, and the winding 320 is directly wound on the magnetic core to form a coil.

[0033] Reference Figures 1 to 3 In some embodiments of the present invention, the fixing structure 400 includes a pressing piece 410 , and the winding seat 310 is located between the base 100 and the pressing piece 410 . The pressing piece 410 is detachably connected to the base 100 to clamp the winding seat 310 .

[0034] The pressing member 410 is pressed against the winding seat 310 and the winding seat 310 is clamped with the base 100 to limit the movement of the winding seat 310. The winding seat 310 can be fixed by connecting the pressing member 410 with the base 100, which has a simple structure and is easy to assemble. The pressing member 410 and the base 100 can be detachably connected by a threaded connection or by a snap connection.

[0035] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the fixing structure 400 also includes a positioning protrusion 420 and a positioning recess 430, one of the positioning protrusion 420 and the positioning recess 430 is arranged on the winding seat 310, and the other is arranged on the base 100 or the pressing member 410, and the positioning protrusion 420 can extend into the positioning recess 430.

[0036] When the base 100 and the pressing member 410 clamp the winding base 310, the positioning protrusion 420 extends into the positioning recess 430, which can further limit the movement of the winding base 310 relative to the base 100 or the pressing member 410, making the overall structure more stable and helping to improve stability. The positioning protrusion 420 can be a protruding block integrally provided on the winding base 310, the base 100, or the pressing member 410, and the positioning recess 430 can be a groove or opening that matches the protruding block.

[0037] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the rotor 200 includes a rotating shaft 210 and a permanent magnet 220 disposed on the rotating shaft 210, a first through hole 110 is disposed on the base 100 to allow one end of the rotating shaft 210 to pass through, and a second through hole 411 is disposed on the pressing member 410 to allow the other end of the rotating shaft 210 to pass through.

[0038] The rotor 200 is formed by arranging a permanent magnet 220 on the rotating shaft 210, which has a simple structure and is easy to implement. In addition, by using the permanent magnet 220, the rotor 200 does not need to generate a magnetic field by using the electromagnetic effect through connection with a wire, and is more convenient to use. In addition, when the base 100 and the pressing member 410 clamp the winding seat 310, the two ends of the rotor 200 pass through the first through hole 110 and the second through hole 411 respectively, that is, the rotor 200 is also restricted between the base 100 and the pressing member 410 and is surrounded by the winding module 300, so that the rotor 200 is movably connected to the base, which has a simple structure and is easy to implement.

[0039] In some embodiments of the present invention, a first bearing and a second bearing are further included. The first bearing is connected to the wall surface of the first through hole 110 , and the second bearing is connected to the wall surface of the second through hole 411 .

[0040] One end of the rotating shaft 210 is connected to the first bearing when passing through the first through hole 110, and the other end of the rotating shaft 210 is connected to the second bearing when passing through the second through hole 411, so that when the winding module 300 generates a magnetic field to drive the permanent magnet 220 to drive the rotating shaft 210 to rotate, the rotation resistance of the rotating shaft 210 can be reduced, which is conducive to improving the conversion efficiency of converting electrical energy into mechanical energy. The first bearing and the second bearing can be implemented in the form of ball bearings or self-lubricating bearings.

[0041] Reference Figures 1 to 3 In some embodiments of the present invention, the number of the winding modules 300 is four, and the four winding modules 300 are evenly distributed circumferentially with the rotor 200 as the center.

[0042] The four winding modules 300 are evenly distributed around the rotor 200 , that is, two adjacent winding modules 300 are vertically arranged, which is conducive to making the magnetic field generated by the winding modules 300 more uniform so as to drive the rotor 200 to rotate more efficiently.

[0043] Reference Figures 1 to 4 The pulse motor system according to the second embodiment of the present invention includes the above-mentioned motor and also includes a pulse driving module 500, which is electrically connected to the winding module 300.

[0044] The pulse drive module 500 generates a pulse drive signal and transmits it to the winding module 300. The winding module 300 forms a rotating magnetic field driven by the pulse drive signal, thereby driving the rotor 200 to rotate. By using the pulse drive signal, the rotation angle of the rotor 200 is positively correlated with the number of pulses, and the rotation speed of the rotor 200 can be accurately controlled. At the same time, the pulse drive signal has high anti-interference performance, which is conducive to improving reliability. In addition, when the winding module 300 fails or is damaged, the winding module 300 can be replaced separately, which is convenient for maintenance.

[0045] refer to Figure 4 In some embodiments of the present invention, the pulse driving module 500 includes a pulse unit 510, an adjustment unit 520 and a driving unit 530. The adjustment unit 520 is electrically connected to the control end of the pulse unit 510 to adjust the pulse width generated by the pulse unit 510. The input end of the driving unit 530 is connected to the output end of the pulse unit 510. The output end of the driving unit 530 is electrically connected to the winding module 300.

[0046] The pulse unit 510 generates a pulse signal and transmits it to the driving unit 530. The driving unit 530 enhances the driving capability of the pulse signal, converts it into a pulse driving signal and transmits it to the winding module 300. The adjustment unit 520 controls the pulse width generated by the pulse unit 510. Since the pulse width of the pulse signal affects the rotation speed of the rotor 200, the user can adjust the rotation speed of the rotor 200 according to the usage requirements through the adjustment unit 520, making it more convenient to use.

[0047] refer to Figure 4 In some embodiments of the present invention, the pulse unit 510 is an oscillator, the adjustment unit 520 is an adjustable resistor R3, and the driving unit 530 includes a switch tube Q1, a switch tube Q2, a switch tube Q3 and a resistor R1; the oscillator can generate a pulse signal by oscillating, and the variable resistor R3 is connected to the control end of the oscillator to change the pulse signal output by the oscillator by changing its own resistance; the input end of the switch tube Q1 is connected to the power supply end, the control end of the switch tube Q1 is respectively connected to the control end of the switch tube Q3 and the output end of the oscillator, the output end of the switch tube Q1 is respectively connected to the input end of the switch tube Q3, one end of the resistor R1 and the control end of the switch tube Q2, the input end of the switch tube Q2 is connected to the winding module 300, L2 is a coil of one of the winding modules 300, and the output end of the switch tube Q2, the other end of the resistor R1 and the output end of the switch tube Q3 are grounded.

[0048] The pulse signal is generated by the oscillator, and programming development is not required, and it is easy to use. The user can adjust the rotor 200 speed by adjusting the adjustable resistor R3, which is easy to operate. The driving ability of the pulse signal is enhanced by the structure of the switch tube Q1, the switch tube Q2, the switch tube Q3 and the resistor R1, and the structure is simple and easy to implement.
