[0034] Please refer to Figures 1-7 , the present invention provides a technical solution: an energy-saving variable-frequency three-phase asynchronous motor, including a motor protection mechanism 1, a rear cover mechanism 2, and a frequency conversion adjustment mechanism 3 for implementing variable-frequency rotation;

[0035] The motor protection mechanism 1 includes a protective cover 11 for covering. A concave slot 12 is opened on the side of the protective cover 11. In the middle of the top of the concave slot 12, a conical connection base 13 is installed. At the top of the conical connection base 13, a connecting pin 14 for binding is installed.

A toggle sleeve 192 for toggle is provided at the top of the adjusting wire 191, and a surrounding magnetic head 193 is sleeved at the middle of the top of the toggle sleeve 192.

[0037] In this embodiment: a stator 4 for driving is arranged around one end of the magnetic head 193;

[0038] The stator 4 includes a surrounding magnetic sheet 41 for assembly, the outer portion of the surrounding magnetic sheet 41 is covered with an arc-shaped shifting sheet 42 for driving, and a circular opening 43 is opened in the middle of the arc-shaped shifting sheet 42;

[0039] Both ends of the arc-shaped toggle piece 42 are provided with magnetic copper rings 44 .

[0040] The main purpose of adopting the arc-shaped paddle 42 and the circular opening 43 is to realize the combination of each surrounding magnetic head 193.

[0041] In this embodiment: the edges of the magnetic copper ring 44 are all around the surface of the designated arc-shaped toggle piece 42, the surface of the arc-shaped toggle piece 42 is installed with an access gasket 45, the surface of the arc-shaped toggle piece 42 is surrounded by a magnetic copper ring 44, and one end of the arc-shaped toggle piece 42 is provided with an electromagnetic ring 46.

[0042] In this embodiment: the end of the rotor 16 is installed with the end transmission mechanism 5, and the end transmission mechanism 5 includes a bonding sheet 51 installed at one end of the rotor 16, and a transmission shaft sleeve 52 for combination is installed at one end of the bonding sheet 51, and an assembly base 53 is installed at the edge of the transmission shaft sleeve 52, and a circular groove 54 is opened on the surface of the assembly base 53.

[0043] The fitting sheet 51 and the transmission shaft sleeve 52 are matched with the rotor 16 in the sleeve connection link and assembled with the middle part of the rear cover of the rear housing.

[0044] In this embodiment: a rear cover mechanism 2 is installed at the rear end of the protective cover 11, and the rear cover mechanism 2 includes a rear cover 21 installed at the rear end of the protective cover 11, an adjustment rear slot 22 is opened in the middle of the rear cover 21, and an access base 23 is installed at the bottom of the protective cover 11, and a trapezoidal base 24 is installed on the bottom of the access base 23.

[0045] The rear cover 21 is adopted to realize the support of the rotor 16 after the other side of the rotor 16 is rotated, and the rear cover 21 and the rear slot 22 are adjusted to realize the installation.

[0046] In this embodiment: the frequency conversion adjustment mechanism 3 includes a frequency converter 31 installed on the side wall of the protective cover 11, the side wall of the frequency converter 31 is installed with a side wall toggle roller 32, a guide slot 33 is installed in the middle of the end of the side wall toggle roller 32, and a toggle rod 34 is provided at the end of the guide slot 33.

[0047] The side wall toggle roller 32 and the guide slot 33 are combined and spliced with one end of the rod body of the toggle rod 34 at the slot stage.

[0048] In this embodiment, a variable frequency speed regulating box 35 is installed on the side of the frequency converter 31 , and a wiring slot 36 is installed on the top of the variable frequency speed regulating box 35 .

[0049] The frequency conversion speed regulating box 35 and the wiring slot 36 are combined.

[0050] First step: Assemble the three-phase asynchronous motor as needed:

[0051] At this moment, the motor needs to be assembled with the ground according to the area of the access base 23 below;

[0052] After assembly, the holes on the surface of the access base 23 are faced to ensure that the motor protection cover 11 can be firmly installed and fixed to the ground. After that, the personnel deflect the designated toggle rod 34 and the side wall of the top to toggle the roller 32. After the transmission structure based on the middle of the top is deflected and rotated, the power supply is uniformly realized;

[0053] Step 2: Motor drive;

[0054] The detailed three-phase principle of motion at this moment is that the action of the current forms a set of autonomously rotating magnetic fields at the positions of several circles of magnetic rings 46, and then under the influence of the magnetic field electricity, the positions of multiple arc-shaped shifting pieces 42 can be wrapped and combined, and the magnetic force increased by the electricity can be exerted on multiple stators 4 around. The stator 4 is in a donut state based on the formed magnetic flow field, that is, a surrounding magnetic space is formed based on the arc-shaped shifting piece 42. This magnetic space will generate rotational power with the interlaced and sleeved rotor 16 and the wrapped copper wire 17 and the wound copper wire 18. At this moment, the rotor 16 will determine that the rotation of the motor end can be maintained in a fixed state between the bonding piece 51 and the assembly base 53 in the mechanism, and the other end that actually realizes the rotation output, that is, the end surrounding the magnetic head 193 will generate a high-speed rotational force to drive the outermost metal shaft to rotate;

[0055] Step 3: Frequency conversion and speed regulation of the motor;

[0056] In this process, based on manually swinging the lever 34, the specific rotation scheme is realized by swinging along the surface of the roller 32 and the guiding slot 33 on the side wall. When the rod body of the lever 34 flips at this moment, the frequency converter 31 at the rear end generates electricity, and finally changes the power transmission voltage of the variable frequency speed control box 35, and finally ensures that the rotational speed of the motor can be accurately regulated. When in use, the appropriate rotational speed can be independently selected according to needs to achieve the energy-saving effect.
