Detailed Description
The technical solution provided by the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the structure diagram of the split-type motor provided by the present invention is shown, and the split-type motor includes a fixed portion and a rotating portion separable from the fixed portion, where the fixed portion includes at least a non-magnetic base and a stator fixed on the base, the rotating portion includes at least a non-magnetic turntable cover and a rotor disposed in the turntable cover, and the turntable cover and the base have a clamping structure, and when clamping is performed, the rotor can rotate freely. That is, the turntable cover has a structure for fixing the rotor so that the rotor is fixed in the axial direction and the rotor can freely rotate about the rotation axis. In a preferred embodiment, the rotor is further provided with a rotatable bearing, the bearing is arranged at the center of the rotor in a penetrating manner, and the turntable cover and the bearing base have a clamping structure. That is, a bearing is fixed on the shaft between the center of the rotor and the equipment requiring power, the bearing serves as a support, and the equipment at the other end of the shaft rotates together when the rotor rotates.
Referring to fig. 2, a schematic structural diagram of a stator of the present invention is shown, which includes at least one first magnetic ring with a circular structure and a plurality of coils that are distributed at intervals along a circumferential direction of the magnetic ring and are fixedly disposed on the magnetic ring, wherein the first magnetic ring is formed by embedding a plurality of constant magnets at intervals, and magnetic poles of adjacent constant magnets on the first magnetic ring are opposite in direction, and the coils are formed by winding a conducting wire; the permanent magnet is a magnet made of permanent magnet material and has magnetism; in a preferred embodiment, the back surfaces of the permanent magnets are connected by a magnetic ring made of soft magnetic material to reduce the magnetic path and enhance the magnetic field intensity over the cross-sectional area of the magnetic path. The coil is connected with a current controller, and the current controller is used for controlling the direct current generated in the coil, controlling the rotating speed of the rotor by controlling the intensity of the current and controlling the steering of the rotor by controlling the flowing direction of the current.
In a preferred embodiment, a stator cover is further provided, and the stator cover can be tightly covered on the stator to fix the first magnetic ring in contact with the rotor cover.
In a preferred embodiment, a stator disk is also provided, which is used to fix the first magnet ring and the base together.
Referring to fig. 3, a schematic structural diagram of the rotor of the present invention is shown, wherein the rotor is provided with a turntable, and the turntable is used for fixing the second magnetic ring and can rotate integrally. At least one second magnetic ring with a circular structure is arranged on the rotary table, and the second magnetic ring is made of soft magnetic materials; the soft magnetic material is not magnetic, and has corresponding magnetism after being magnetized by an external magnetic field and forming a closed magnetic circuit with the constant magnetic body providing the magnetic field.
Therefore, the invention also discloses a driving mechanism of the wall breaking machine, which can be applied to products such as a wall breaking food processor, a juice extractor, a soybean milk machine, an ice cream machine, a food processor, a grinder and the like. Broken wall machine actuating mechanism adopts the split type rotating electrical machines of above-mentioned design, sets up the bearing in the rotating part, and the one end and the rotor of bearing are connected, and the other end and the blade holder main part zonulae occludens of bearing drive the arbor when the carousel is rotatory and rotate together, and the broken wall cutter on the arbor is also driven and is rotated together. Different tools may be exchanged for different applications.
By adopting the structure, when the turntable cover is clamped with the base, the rotor cover and the stator cover can be contacted with each other and can also have certain space intervals; at the moment, the second magnetic ring on the rotor and the first magnetic ring on the stator are concentric same-diameter magnetic rings which are distributed up and down; because the surface of the first magnetic ring permanent magnet has remanence, under the action of the remanence magnetic field on the surface of the first magnetic ring permanent magnet, the second magnetic ring made of soft magnetic material is magnetized and forms a closed magnetic circuit corresponding to the first magnetic ring, so that magnetic attraction exists between the rotor and the stator to be tightly fixed; because the position relation between the permanent magnet and the coil in the stator is fixed, the direction of a magnetic field vertical to the coil is fixed and unchanged relative to the coil, and when direct current in a certain direction flows through the coil, Lorentz force is generated to enable the rotor to be stressed and rotated; the current controller controls the magnitude of the direct current in each coil to enable the rotor to rotate according to a certain rotating speed. That is, the rotation speed and the output torque of the motor can be controlled by controlling the magnitude of the direct current in the coil through the current controller. The specific working principle is as follows:
referring to fig. 4, which is a schematic view showing the working principle of the split-type motor of the present invention, the magnetized closed magnetic circuit is shown, the magnetic material on the rotor corresponding to the N-level permanent magnets on the stator is magnetized into S-level, correspondingly, the magnetic material corresponding to the S-level permanent magnets on the stator is magnetized into N-level, and then the first magnetic ring and the second magnetic ring form an integral closed magnetic circuit. Therefore, when the fixed part and the dividable rotating part are put together, not only the magnetic force makes them tightly fixed to each other, but also the remanence of the permanent magnet on the stator magnetizes the soft magnetic material on the rotor to form a closed magnetic circuit and provides a magnetic field for the lorentz force generated by the current in the wires.
The coil fixed on the permanent magnet has a cross section equivalent to a lead wire for current to flow in or out, and the coil is placed in a fixed magnetic field because the direction of the magnetic field of the permanent magnet is unchanged. The direction of magnetic force lines formed between the conducting wires and the magnetic ring is vertical, when direct current flows into the conducting wires (х in the figure represents current flowing out and current flowing in), the electrified conducting wires form Lorentz force in a vertical magnetic field, the stator is subjected to circumferential force, the Lorentz force is reversely transmitted to the rotor due to the fixed arrangement of the stator, and the rotor can rotate when the attraction force between the stator and the rotor is overcome. As shown in fig. 4, when a direct current is generated in the coil, the currents generated therein respectively flow through the adjacent permanent magnets and have opposite directions on the adjacent permanent magnets, and when the magnetic poles of the adjacent permanent magnets have opposite directions, the same direction of the generated lorentz force can be ensured. In addition, the coil is made to flow through the current above the magnet in multiple sections by winding multiple turns, so that a smaller current can generate a larger lorentz force. Therefore, because the magnetic poles of the adjacent permanent magnets are opposite, when the same coil is in the magnetic field, the current flowing directions of the coil on the adjacent permanent magnets are just opposite, so that Lorentz force in the same direction is generated, and the rotor is pushed to rotate together. In this mode, the rotational speed of the turntable is changed by changing the magnitude of the direct current.
Referring to fig. 5, a winding diagram of a coil and a constant magnet in a preferred embodiment is shown, the coil is represented by a dotted line, and in the winding mode, when the coil is in a standard position, one coil is correspondingly arranged between any two adjacent constant magnets. Therefore, the number of coils is the same as the number of constant magnets distributed on the rotor.
Referring to fig. 6, a schematic winding diagram of a coil and a permanent magnet in another preferred embodiment is shown, in which each adjacent permanent magnet is in a group and two are combined, and each group is provided with a coil when in a standard position. Therefore, the number of coils is half of the number of the constant magnets distributed on the rotor.
Preferably, the winding of fig. 5 is used, which has less wire and produces correspondingly less dc resistance loss to achieve the same effect.
Preferably, the soft magnetic material may be: iron material, permalloy, ferrite soft magnetic material, silicon steel sheet and the like, and more preferably, the soft magnetic material is ferrite soft magnetic material to reduce loss.
In a preferred embodiment, the second magnetic ring is a circular ring integrally formed by soft magnetic materials or a circular ring formed by splicing U-shaped soft magnetic materials.
In a preferred embodiment, a magnetic material is arranged under the coil, and the magnetic material is a silicon steel sheet. Preferably, the geometry of the coil is trapezoidal. By adopting the technical means, the stability of the rotor during working is improved, the alignment between the stator and the rotor is improved, the silicon steel sheet and the permanent magnet are attracted, the permanent magnets of the two discs correspond to the coils, and meanwhile, the permanent magnet of one circle and the magnetic material of one circle are attracted mutually, so that the stability of the cup body during working is improved; meanwhile, as the magnetic material and the permanent magnet are mutually attracted, when the rotating part is placed, the two disks can be inosculated together by the attraction as long as the positions of the two disks are not greatly deviated.
In the technical scheme, the section of the permanent magnet is trapezoidal, so that a circular ring-shaped magnetic ring is formed. The formed magnetic ring is one or more circles.
In the technical scheme of the invention, the fixed part is also required to be provided with a current controller, and the current controller generates direct currents with different magnitudes and directions according to application requirements so as to enable the current in the coil to generate Lorentz force. Wherein the magnitude determines the rotational speed of the rotor and the direction of the current determines the direction of rotation.
In the application of the split motor, the rotor is connected with a shaft of equipment needing power into a whole, the stator is designed in a split mode and is arranged on the base of the fixed part, when the split motor is used, the rotating part is directly arranged on the fixed part, and the rotor and the stator are attracted by means of magnetic force; during control, the current controller generates alternating current, and the rotor rotates due to the generated Lorentz force. Therefore, under the condition of no connecting shaft, the cutter shaft of the wall breaking machine can be rotated.
