Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a disassembled magnetically isolated permanent magnet synchronous motor and a juicer. Background Art

[0002] A permanent magnet synchronous motor is an electric motor based on the principle of synchronous motion of a magnetic field. It usually includes a stator, a reinforced rotor rod, and a winding. When the stator winding is excited by an AC power supply, a rotating magnetic field is generated, and the permanent magnets on the reinforced rotor rod rotate synchronously under the action of the stator magnetic field. This synchronous rotation allows the motor to convert electrical energy into mechanical energy more efficiently and has good speed regulation performance. The permanent magnet synchronous motor has the characteristics of high efficiency, which means that it can output more mechanical power under the same input power, thereby reducing energy loss. In a juicer, a high-efficiency motor can drive the blade to rotate faster, increase the juicing speed, and reduce power consumption, thereby achieving energy saving.

[0003] Among them, the patent with announcement number CN219779870U discloses a permanent magnet synchronous motor, which belongs to the field of motor technology. The permanent magnet synchronous motor includes a reinforced rotor rod body, which includes a reinforced rotor rod body core stacked by silicon steel sheets. The reinforced rotor rod body core has a mounting groove for a permanent magnet and an outer magnetic isolation bridge located at the outer edge of the reinforced rotor rod body core. The shape of the outer magnetic isolation bridge in the axial projection of the reinforced rotor rod body core is corrugated.

[0004] When this structure is in use, the thickness of the outer magnetic isolation bridge on the permanent magnet synchronous motor is made thinner, thereby increasing the magnetic resistance and reducing the leakage magnetic field. The outer magnetic isolation bridge strengthens the uneven air gap between the rotor rod body and the stator, making the motor back electromotive force waveform sinusoidal and the torque pulsation small, thereby achieving smooth operation of the motor. However, this structure is not easy to gather the magnetic field together when in use, and it is also easy to cause uneven distribution of the magnetic field, resulting in low precise control of its speed, torque and position. Summary of the invention

[0005] The present invention provides a disassembled magnetically isolated permanent magnet synchronous motor and a juicer, aiming to solve the problems raised in the above background technology.

[0006] The present invention is implemented in this way. The present invention provides the following technical solution: a disassembled magnetically isolated permanent magnet synchronous motor comprises a shell, and a deployment component is arranged on the shell.

[0007] The mixing component includes an inner liner arranged in a shell, a gasket is arranged in the middle of the inner liner, a plurality of magnetic sheets are distributed on the inner wall of the gasket, and a dividing groove is formed between each two adjacent magnetic sheets.

[0008] A pad is provided in the middle of the gasket ring, and a reinforced magnetic focusing support cone cover is provided on one side of the pad. The vertical cross-sectional shape of the reinforced magnetic focusing support cone cover is set to be conical, and a plurality of offset openings are distributed on the outer side of the reinforced magnetic focusing support cone cover, and connecting blocks are embedded in the plurality of the offset openings, and a plurality of windings are provided on each of the connecting blocks.

[0009] The middle part of the reinforced magnetic concentrating support cone cover is rotatably connected with a slip ring, one end of the slip ring is fixedly provided with a reinforced rotor rod body, one end of the lining is provided with a magnetic conductive cylinder, one end of the magnetic conductive cylinder is provided with a docking plate, the magnetic conductive cylinder and the docking plate both penetrate the shell and extend to the outside of the shell, a card plate is installed on the outside of the shell by bolts, a controller for controlling the current is installed on the card plate by bolts, sliding rods are inserted at both ends of the card plate, and a sliding sleeve is sleeved on the outside of each sliding rod, the sliding sleeve is slidably connected to the sliding rod, electric telescopic rods are provided at both ends of the controller, the electric telescopic rods are installed on the card plate by bolts, and the output ends of each electric telescopic rod extend to the corresponding sliding sleeve.

[0010] It can be seen that in the above technical scheme, the current is transmitted through the shunt ring, so that the current is distributed on each stator winding plate and generates current, forming a magnetic field required to strengthen the rotation of the rotor rod body, and the magnetic sheet is used to enhance the magnetic field strength, and the lining is used for shielding to avoid magnetic leakage, thereby improving the efficiency and stability of the motor, and each connecting block and winding are distributed on the enhanced magnetic support cone cover, so that the magnetic field generated by the connecting block and the winding interacts with the magnetic field formed by the stator winding plate to promote the rotation of the enhanced rotor rod body, and at the same time, through the conical cross-section of the enhanced magnetic support cone cover, the magnetic field can be more effectively gathered on the axis line. Gathering the magnetic field on the axis line can maximize the use of magnetic energy, reduce magnetic field leakage and interference, and make the magnetic field act on the casing evenly and stably, which can reduce vibration and noise, improve the running smoothness of the motor, and thus improve the efficiency of the motor, which means that under the same input power, the motor can output more mechanical power.

[0011] Clamp arms are installed on the two sliding sleeves by bolts, and magnetic blocks are arranged on the clamp arms. The vertical cross-section of the magnetic blocks is arranged to be arc-shaped. A groove plate is arranged between the two magnetic blocks. The groove plate cover is arranged on the outer side of the liner. The groove plate is installed on the shell by bolts. A restraining cylinder is arranged in the middle of the groove plate, and an extension cylinder is arranged at one end of the restraining cylinder. The restraining cylinder and the extension cylinder are both located in the middle of the gasket. A plurality of stator winding plates are distributed between the liner and the gasket, and a shunt ring is clamped on each of the stator winding plates.

[0012] It can be seen that in the above technical solution, the sliding sleeve is driven to slide on the sliding rod through the electric telescopic rod, and then the clamping arm drives the magnetic block to move, so that the magnetic block can approach or move away from the constraint cylinder, thereby realizing the function of controlling its magnetic field, and realizing the motor to increase the direct-axis demagnetization current component and reduce the cross-axis current component to weaken the air gap synthetic magnetic field, thereby increasing the motor speed.

[0013] A juicer includes the above-mentioned disassembled magnetically isolated permanent magnet synchronous motor, including a juicer body covered on the outside of a shell, a control button panel is provided on the juicer body, and the control button panel is electrically connected to a controller, a juicer barrel is provided on the top of the magnetic conductive block, and one end of the reinforced rotor rod body extends to the bottom of the inner cavity of the juicer barrel.

[0014] The present invention has the following advantages: The present invention uses a controller to pass a three-phase symmetrical current into the shunt coil, and the current is transmitted through the shunt coil, so that the current is distributed on each stator winding plate and generates current, forming a magnetic field required for the rotation of the enhanced rotor rod body, so that the magnetic field acts on the enhanced rotor rod body uniformly and stably, avoiding the instability of the rotation of the enhanced rotor rod body caused by the uneven magnetic field; The conical cross section of the reinforced magnetic concentrating support cone cover of the present invention can more effectively gather the magnetic field on the axis line. Gathering the magnetic field on the axis line can maximize the use of magnetic energy, reduce the leakage and interference of the magnetic field, and make the magnetic field act on the reinforced rotor rod body uniformly and stably, which can reduce vibration and noise, improve the running stability of the motor, and thus improve the efficiency of the motor, which means that under the same input power, the motor can output more mechanical power; When the rotation speed of the rotor rod body approaches its limit value, in order to further expand the speed regulation range, the electric telescopic rod drives the sliding sleeve to slide on the sliding rod, and then the clamp arm drives the magnetic block to move, so that the magnetic block can approach or move away from the constraint cylinder, and the function of controlling its magnetic field is realized, so that the motor increases the direct axis demagnetization current component and reduces the quadrature axis current component, so as to weaken the air gap synthetic magnetic field, thereby increasing the motor rotation speed; To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the current is transmitted through the shunt ring, so that the current is distributed on each stator winding plate and generates current, forming the magnetic field required for the rotation of the enhanced rotor rod body, so that the magnetic field acts on the enhanced rotor rod body evenly and stably, avoiding the uneven magnetic field and causing unstable rotation of the enhanced rotor rod body. The conical cross-section of the enhanced magnetic concentrating support cone cover can more effectively gather the magnetic field on the axis line. Gathering the magnetic field on the axis line can maximize the use of magnetic energy and reduce leakage and interference of the magnetic field, so that the magnetic field acts on the enhanced rotor rod body evenly and stably, which can reduce vibration and noise, improve the running smoothness of the motor, and thus improve the efficiency of the motor, which means that under the same input power, the motor can output more mechanical power.

[0028] As attached Figure 1-Figure 10 A disassembled magnetically isolated permanent magnet synchronous motor is shown, through the adjustment components arranged on the shell 1, through the corresponding coordination of various structures, the current is transmitted through the shunt ring 26, so that the current is distributed on each stator winding plate 25 and generates current, forming the magnetic field required for the rotation of the enhanced rotor rod body 12, so that the magnetic field acts on the enhanced rotor rod body 12 evenly and stably, avoiding the occurrence of uneven magnetic field and causing unstable rotation of the enhanced rotor rod body 12. The conical cross-section of the enhanced magnetic concentrating support cone cover 7 can more effectively gather the magnetic field on the axis line. Gathering the magnetic field on the axis line can maximize the use of magnetic energy, reduce leakage and interference of the magnetic field, and make the magnetic field act on the enhanced rotor rod body 12 evenly and stably, which can reduce vibration and noise, improve the running stability of the motor, and thus improve the efficiency of the motor. This means that under the same input power, the motor can output more mechanical power, and the specific structural arrangement of the components is as follows.

[0031] A clamping arm 20 is installed on both sleeves 19 by bolts, and a magnetic block 21 is arranged on the clamping arm 20. The vertical cross-section shape of the magnetic block 21 is set to be an arc shape. A groove plate 22 is arranged between the two magnetic blocks 21. The groove plate 22 cover is arranged on the outer side of the liner 2. The groove plate 22 is installed on the shell 1 by bolts. A restraining cylinder 23 is arranged in the middle of the groove plate 22, and an extension cylinder 24 is arranged at one end of the restraining cylinder 23.
