Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a switched reluctance motor for a food processor, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a switched reluctance motor for a food processor, comprising a protective shell, wherein a regulating component is arranged on the protective shell;

[0007] The regulating assembly comprises a pad arranged in the protective shell, a stator is arranged on the top of the pad, an extension rod is rotatably connected to the bottom of the stator, and the extension rod is mounted on the pad by bolts;

[0008] A plurality of slide rails are distributed on the outer side of the extension rod, and each of the slide rails is slidably connected with a resistance block, and one end of each of the resistance blocks is embedded with a strengthening magnetization sheet;

[0009] A connecting disk is provided at the top of the stator, and an offset groove is provided on the outer side of the connecting disk. A plurality of induction magnetic blocks are distributed on the top and bottom of the inner wall of the offset groove, and each of the induction magnetic blocks is respectively located at the top and bottom of the reinforced magnetization sheet body. A connecting shaft is provided in the middle of the stator, and a reinforced rotor rod is threadedly connected to the connecting shaft. Coils are provided on the outer sides of the reinforced rotor rod and the connecting shaft, and each of the coils is respectively located in the middle of the stator and the connecting disk. A card frame is clamped at the top of each of the extension rods, and a Hall sensor is embedded in each of the card frames.

[0010] It can be seen that in the above technical solution, when current is passed through the stator, a rotating magnetic field will be generated around the coil, and this magnetic field will interact with the iron core of the reinforced rotor rod and the connecting shaft to generate magnetic force. Under the action of the magnetic force, the reinforced rotor rod and the connecting shaft will move to the position with the strongest magnetic field strength, and the current in the stator will be changed, so that the magnetic field changes. The reinforced rotor rod and the connecting shaft are subjected to the new magnetic force and are continuously attracted to the new position with the largest magnetic field. By continuously changing the current in the stator, the reinforced rotor rod and the connecting shaft can be made to move continuously;

[0012] It can be seen that in the above technical solution, the second micro motor drives the first strengthening and adjusting traction rod to rotate, and the first strengthening and adjusting traction rod rotates to pull the second strengthening and adjusting traction rod to move, so that the resistance block can slide on the slide rail, so that the strengthening magnetization sheet can be close to the connecting disk, and then the strengthening magnetization sheet extends to between the two adjacent induction magnetic blocks, so that the magnetic field can be enhanced by the induction magnetic blocks and the strengthening magnetization sheet, so as to keep the voltage unchanged and change the waveform width, peak value and effective value of the current, so as to affect the output torque, and then affect the strengthening of the rotor rod and the connecting shaft torque. When the deflection rod rotates, the position of the stator is fine-tuned, so that the Hall sensor on the outside of the stator can be easily adjusted along the axis point of the stator, so that the Hall sensor is close to the strengthening magnetization sheet. By detecting the magnetic field with the Hall sensor, key parameters such as magnetic flux, inductance, and back electromotive force inside the motor can be obtained, thereby realizing real-time monitoring and precise control of the motor state, and easily meeting the needs of various complex working conditions.

[0014] 1. When the present invention passes current through the stator, a rotating magnetic field is generated around the coil. This magnetic field interacts with the iron core of the reinforced rotor rod and the connecting shaft to generate magnetic force. Under the action of the magnetic force, the reinforced rotor rod and the connecting shaft will move to the position with the strongest magnetic field strength.

By continuously changing the current in the stator, the reinforced rotor rod and the connecting shaft can be continuously moved.

[0015] 2. The present invention enables the resisting block to slide on the slide rail, so that the reinforcing magnetizing sheet can approach the connecting plate, and then the reinforcing magnetizing sheet extends between two adjacent induction magnetic blocks, so that the magnetic field can be enhanced through the induction magnetic blocks and the reinforcing magnetizing sheet, so as to maintain the voltage unchanged and change the waveform width, peak value and effective value of the current, so as to affect the output torque, and then strengthen the torque of the rotor rod and the connecting shaft;

[0016] 3. The present invention fine-tunes the position of the stator when the deflection rod rotates, so that the Hall sensor on the outside of the stator can be easily adjusted along the axis of the stator, so that the Hall sensor is close to the magnetizing sheet. By detecting the magnetic field through the Hall sensor, key parameters such as the magnetic flux, inductance, and back electromotive force inside the motor can be obtained, thereby achieving real-time monitoring and precise control of the motor state, and easily meeting the needs of various complex working conditions;

[0017] To sum up, through the corresponding coordinated use of various structures, the magnetic field changes, the strengthened rotor rod and the connecting shaft are subjected to the new magnetic force, and are constantly attracted to the position where the new magnetic field is maximum.

[0029] As attached Figure 1 - Figure 8 The switched reluctance motor for a food processor shown in the figure changes the magnetic field through the control component set on the protective shell 1, and the reinforcing rotor rod 12 and the connecting shaft 13 are subjected to the new magnetic force and are constantly attracted to the new position with the maximum magnetic field. By constantly changing the current in the stator 3, the reinforcing rotor rod 12 and the connecting shaft 13 can be continuously moved, so that the reinforcing magnetizing sheet 7 can be close to the connecting disk 8, and then the reinforcing magnetizing sheet 7 can be extended between two adjacent induction magnetic blocks 10, so that the magnetic field can be enhanced through the induction magnetic blocks 10 and the reinforcing magnetizing sheet 7, so as to keep the voltage unchanged and change the waveform width, peak value and effective value of the current, so as to affect the output torque, and then affect the torque of the reinforcing rotor rod 12 and the connecting shaft 13. The Hall sensor 15 is close to the reinforcing magnetizing sheet 7. By detecting the magnetic field through the Hall sensor 15, the key parameters such as the magnetic flux, inductance, and back electromotive force inside the motor can be obtained, so as to realize real-time monitoring and precise control of the motor state, which is easy to meet the needs of various complex working conditions, and the specific structure of the component is set as follows;

[0030] The regulating component includes a pad 2 arranged in the protective shell 1, a stator 3 is arranged on the top of the pad 2, an extension rod 4 is rotatably connected to the bottom of the stator 3, and the extension rod 4 is installed on the pad 2 by bolts;

[0031] A plurality of slide rails 5 are distributed on the outer side of the extension rod 4, and each slide rail 5 is slidably connected with a resistance block 6, and one end of each resistance block 6 is embedded with a strengthening magnetization sheet 7;

[0032] A connecting disk 8 is provided at the top of the stator 3, and an offset groove 9 is opened on the outer side of the connecting disk 8. A plurality of induction magnetic blocks 10 are distributed on the top and bottom of the inner wall of the offset groove 9, and each induction magnetic block 10 is respectively located at the top and bottom of the reinforced magnetizing sheet 7. A connecting shaft 13 is provided in the middle of the stator 3, and a reinforced rotor rod 12 is threadedly connected to the connecting shaft 13. Coils 11 are provided on the outer sides of the reinforced rotor rod 12 and the connecting shaft 13, and each coil 11 is respectively located in the middle of the stator 3 and the connecting disk 8. A card frame 14 is clamped on the top of each of the extension rods 4, and a Hall sensor 15 is embedded in each card frame 14.

[0033] A first micro motor 16 is installed on the top of the pad 2 by bolts, and a deflection rod 17 is provided at the output end of the first micro motor 16, and one end of the deflection rod 17 extends to the outside of the stator 3. A second micro motor 18 is installed on one end of the slide rail 5 by bolts, and a first strengthening adjustment traction rod 19 is fixedly provided at the output end of the second micro motor 18.

[0034] According to the above structure, when in use, when current is passed through the stator 3, a rotating magnetic field will be generated around the coil 11, and this magnetic field will interact with the iron core of the reinforced rotor rod 12 and the connecting shaft 13 to generate magnetic force. Under the action of the magnetic force, the reinforced rotor rod 12 and the connecting shaft 13 will move to the position where the magnetic field intensity is the strongest, and the current in the stator 3 will be changed, causing the magnetic field to change.

When the deflection rod 17 rotates, the position of the stator 3 is fine-tuned, so that the Hall sensor 15 on the outside of the stator 3 can be easily adjusted along the axis point of the stator 3, so that the Hall sensor 15 is close to the enhanced magnetization sheet 7. By detecting the magnetic field through the Hall sensor 15, key parameters such as the magnetic flux, inductance, and back electromotive force inside the motor can be obtained, thereby realizing real-time monitoring and precise control of the motor state, and easily meeting the needs of various complex working conditions.

By constantly changing the current in the stator 3, the strengthened rotor rod 12 and the connecting shaft 13 can be continuously moved, so that the strengthened magnetizing sheet 7 can be close to the connecting disk 8, and then the strengthened magnetizing sheet 7 can be extended to between two adjacent induction magnetic blocks 10, so that the magnetic field can be enhanced by the induction magnetic blocks 10 and the strengthened magnetizing sheet 7, so as to keep the voltage unchanged while changing the waveform width, peak value and effective value of the current, so as to affect the output torque, and then affect the torque of the strengthened rotor rod 12 and the connecting shaft 13. The Hall sensor 15 is close to the strengthened magnetizing sheet 7. By detecting the magnetic field through the Hall sensor 15, key parameters such as the magnetic flux, inductance, and back electromotive force inside the motor can be obtained, thereby realizing real-time monitoring and precise control of the motor state, and easily meeting the needs of various complex working conditions.
