Description
Technical Field
[0001] This application belongs to a modeling method, and particularly relates to a 2D mirror motor modeling method and related devices for an axial-radial hybrid magnetic circuit motor. Background Art
[0002] For an axial-radial hybrid magnetic circuit motor, the 3D finite element method must be used to accurately calculate its performance indicators. However, 3D finite element calculation is very time-consuming and will occupy a large amount of computer storage space, resulting in a very high cost for the design and optimization of the axial-radial hybrid magnetic circuit motor. Against this background, it has become extremely urgent to convert the 3D model of the axial-radial hybrid magnetic circuit motor into a 2D model for solution.
[0003] Currently, there have been many studies on the technology of converting a 3D motor model into a 2D equivalent model, but these studies mainly focus on axial flux permanent magnet motors, and the converted 2D equivalent models are mostly single-sided or double-sided linear motors. Since the axial flux permanent magnet motor has only a single axial magnetic circuit, in essence, it still unfolds the stator and rotor of the motor from a rotating configuration into a linear configuration, and only a small number of parameters of the motor need to be converted. However, due to the special axial-radial hybrid magnetic circuit of the axial-radial hybrid magnetic circuit motor, the traditional single-sided linear motor or double-sided linear motor can only be equivalent to a single magnetic circuit and cannot be used to establish a 2D equivalent model of the axial-radial hybrid magnetic circuit motor. Summary of the Invention

[0030] Compared with the prior art, the present application has the following beneficial effects: The present application proposes a 2D mirror motor modeling method for an axial-radial hybrid magnetic circuit motor, and constructs a 2D mirror motor structure model of the axial-radial hybrid magnetic circuit motor. The 2D mirror motor structure model includes a primary iron core, an upper secondary iron core, a lower secondary iron core, and an O-shaped supermagnetic conductor, as well as two first permanent magnets respectively arranged on two opposite surfaces of the supermagnetic conductor.

[0040] An axial-radial hybrid magnetic circuit motor refers to a motor with a hybrid magnetic circuit structure in which both axial magnetic flux and radial magnetic flux exist inside the motor. This kind of motor contains both the radial magnetic field generated by the radial excitation winding and the axial magnetic field generated by the axially magnetized permanent magnet and the axial excitation coil. The motor works by the interaction of the radial magnetic field and the axial magnetic field. This design of the hybrid magnetic circuit enables the motor to have significant advantages in terms of structure, performance, and application scenarios. The working principle of the axial-radial hybrid magnetic circuit motor is that when current passes through the windings of the stator, a magnetic field is generated, and these magnetic fields interact with the magnetic field generated by the permanent magnet, thereby generating a torque on the rotor and driving the rotor to rotate. Since both axial and radial magnetic flux paths exist inside the motor, this interaction is more complex and efficient, enabling the motor to output higher torque and power while maintaining a smaller volume and weight.
[0041] In practical applications, the axial flux permanent magnet motor has a single axial magnetic circuit, and the 2D equivalent model can be established by expanding the stator and rotor from a rotating configuration to a linear configuration and converting a small number of parameters. However, the axial-radial hybrid magnetic circuit motor has a special magnetic circuit structure, that is, it contains both axial and radial magnetic circuits. The traditional single-sided or double-sided linear motor model cannot completely be equivalent to this complex magnetic circuit structure. Based on this situation, the present application proposes a 2D mirror motor modeling method and related devices for an axial-radial hybrid magnetic circuit motor. The present application is described in detail below in conjunction with the embodiments and drawings.
[0042] like Figure 1 As shown, it is a schematic diagram of a 2D mirror motor modeling method of the axial radial hybrid magnetic circuit motor of the present application, which may include: S101, constructing a 2D mirror motor structure model of an axial-radial hybrid magnetic circuit motor; the 2D mirror motor structure model includes a primary iron core, an upper secondary iron core, a lower secondary iron core and a U-shaped super magnet, and two first permanent magnets respectively arranged on two opposite surfaces of the super magnet, the primary iron core is arranged at the center position between the two first permanent magnets, an upper winding is wound between adjacent teeth at the upper end of the primary iron core, a lower winding is wound between adjacent teeth at the lower end of the primary iron core, the upper secondary iron core is arranged on a first permanent magnet, located at a first The lower secondary core is arranged on another first permanent magnet and is located between the other first permanent magnet and the primary core, and the teeth of the upper secondary core and the lower secondary core are arranged alternately; the axial-radial hybrid magnetic circuit motor includes a rotor part and a stator core sleeved outside the rotor part; the rotor part includes a plurality of intermediate rotor cores arranged along the axial direction, a second permanent magnet is arranged between adjacent intermediate rotor cores, and end rotor cores are respectively arranged on the outer sides of the intermediate rotor cores located at both ends of the axial direction; the rotor teeth of adjacent intermediate rotor cores are arranged alternately along the axial direction.
[0043] It should be noted that the primary core is responsible for generating and transmitting the magnetic field. In the 2D mirror model, the primary core can be represented as a structure with multiple teeth, on which windings are wound to generate a magnetic field. The upper secondary core and the lower secondary core are located above and below the primary core, respectively, and are staggered with the teeth of the primary core. The function of the secondary core is to interact with the magnetic field generated by the primary core to generate electromagnetic force or electromagnetic torque. The U-shaped super magnet is a special structure surrounding the primary core and the secondary core, which is used to enhance and guide the magnetic field. The U-shaped design helps to transmit the magnetic field in the axial and radial directions at the same time. The first permanent magnet is arranged on two opposite surfaces of the super magnet to provide a constant magnetic field. The upper winding and the lower winding are respectively wound between adjacent teeth at the upper end of the primary core and between adjacent teeth at the lower end, responsible for generating a changing magnetic field, interacting with the permanent magnet and the secondary core.
[0044] In addition, the present application can be used for axial-radial hybrid magnetic circuit motors that meet the conditions. The intermediate rotor core is the main component of the rotor part and is responsible for conducting and enhancing the magnetic field. The second permanent magnet is used to provide a stable magnetic field. The end rotor core is used to enclose the magnetic circuit, reduce magnetic leakage, and improve the utilization rate of the magnetic field. The rotor teeth of adjacent intermediate rotor cores are arranged axially staggered, which can increase the coupling area between the rotor teeth and the stator teeth and improve the torque output ability of the motor. The staggered rotor teeth can also reduce the saturation phenomenon of the magnetic circuit and improve the linearity and stability of the motor.
[0045] S102. Determine the number of primary slots and secondary teeth of the 2D mirror motor structure model according to the slot-level matching of the axial-radial hybrid magnetic circuit motor.
[0046] It should be noted that the slot-level matching refers to the matching relationship between the number of slots of the primary iron core and the number of teeth of the secondary iron core of the motor, which determines key parameters such as the pole pitch and pitch of the motor, and thus affects the performance of the motor. According to the specific design requirements of the axial-radial hybrid magnetic circuit motor, selecting appropriate numbers of primary slots and secondary teeth can ensure that the motor has the required performance characteristics.
[0047] S103. Calculate the parameters of the primary iron core, the parameters of the first permanent magnet, the parameters of the upper and lower secondary iron cores, the parameters of the supermagnetic conductor, and the stack length of the primary iron core in the 2D mirror motor structure model according to the structural parameters of the axial-radial hybrid magnetic circuit motor, and jointly use them as the parameters of the 2D mirror motor structure model.
[0048] In practical applications, the parameters of the primary iron core can include tooth width, tooth pitch, stack length, etc., and these parameters determine the magnetic field distribution and electromagnetic performance of the primary iron core. The parameters of the first permanent magnet can include pole direction, size, magnetic energy product, etc., and these parameters affect the magnetic field strength and stability provided by the permanent magnet. The parameters of the upper and lower secondary iron cores can include tooth width, tooth pitch, material, etc., and these parameters determine the interaction effect between the secondary iron core and the primary iron core. The parameters of the supermagnetic conductor can include shape, size, material, etc., and these parameters affect the enhancement and guiding effect of the supermagnetic conductor on the magnetic field. The stack length of the primary iron core is the length of the primary iron core in the axial direction and determines the magnetic field distribution and electromagnetic performance of the motor in the axial direction.
[0049] S104. Determine the material of the 2D mirror motor structure model according to the material of the axial-radial hybrid magnetic circuit motor.
[0050] S105. Set the motion and boundaries, and combine the parameters of the 2D mirror motor structure model and the material of the 2D mirror motor structure model to obtain the 2D mirror motor structure model of the axial-radial hybrid magnetic circuit motor.
[0051] In practical applications, corresponding motion conditions can be set in the model according to the motion mode of the motor. For example, for a rotary motor, the center of rotation and the rotational speed need to be set; for a linear motor, the direction of motion and the speed need to be set. According to the actual working environment of the motor, the boundary conditions of the model are set. For example, the boundary conditions of the magnetic field can be set to simulate the external magnetic field environment of the motor, and the mechanical boundary conditions can be set to simulate the fixing and supporting methods of the motor. Then, the parameters and materials of the 2D mirror motor structure model determined previously are substituted into the model to obtain the 2D mirror motor structure model of the complete axial-radial hybrid magnetic circuit motor, which can be used for subsequent electromagnetic field analysis, performance prediction, and optimization design, etc.
[0052] The modeling method of the axial-radial hybrid magnetic circuit motor of the present application will be described in detail through specific examples as follows. As Figure 2 shown, it is a schematic diagram of an axial-radial hybrid magnetic circuit motor of the present application. The axial-radial hybrid magnetic circuit motor in the present application is a permanent magnet reluctance motor, including a stator core, an end rotor core, an intermediate rotor core, and a disc-shaped second permanent magnet. Among them, the rotor teeth of the end rotor core and the intermediate rotor core are arranged axially staggered, that is, the rotor teeth of a certain rotor core must correspond to the rotor slots of the adjacent rotor core, and the stack length of the intermediate rotor core is twice that of the end rotor core. Specifically, the stator core carries the winding and is a key component for the energy conversion of the motor. As Figure 3 shown, it is a schematic diagram of the winding of the permanent magnet reluctance motor in this embodiment. The end rotor core and the intermediate rotor core together constitute the rotating part of the motor, enabling the motor to generate magnetic fields simultaneously in the axial and radial directions, thereby improving the power density and efficiency of the motor. The use of the disc-shaped second permanent magnet reduces the dependence on external power supplies, improves the efficiency and stability of the motor. The disc-shaped design also helps to form a uniform magnetic field distribution inside the motor.
[0053] As Figure 4 shown, it is a schematic diagram of a part of the parameters of the permanent magnet reluctance motor in this embodiment. As Figure 5 shown, it is a schematic diagram of another part of the parameters of the permanent magnet reluctance motor in this embodiment. The main parameters of the permanent magnet reluctance motor include the outer diameter of the stator D s , the thickness of the stator yoke D e , the pole arc coefficient of the stator teeth α st , the air gap length g , the outer diameter of the rotor D a , the height of the rotor teeth h , the pole arc coefficient of the rotor teeth α rt , the shaft diameter D i , the stack length of the end coreH c , the thickness of the second permanent magnet H PM and the axial length of the motor l m . As Figure 6 shown, it is a schematic structural diagram of the 2D mirror motor structure model in this embodiment, including a square-shaped supermagnetic conductor, a strip-shaped first permanent magnet, a primary iron core, an upper winding, a lower winding, an upper secondary iron core, and a lower secondary iron core. The characteristic of this 2D mirror motor structure model is that it uses a square-shaped supermagnetic conductor with a very high relative magnetic permeability but non-existent in reality to communicate with the strip-shaped first permanent magnet on the secondary of the motor, and the bilateral secondary iron cores are interlaced, that is, the teeth of the upper secondary iron core correspond to the slots of the lower secondary iron core. As Figure 7 shown, it is a schematic diagram of the structural parameters of the 2D mirror motor structure model in this embodiment, mainly including the length l sc , width l sk and thickness w sm of the supermagnetic conductor, the length l pm and thickness h pm of the first permanent magnet, the end tooth width w rth and the middle tooth width w rt of the secondary iron core, the tooth height h 0, the slot width w rc of the secondary iron core, the yoke thickness d re of the secondary iron core, the length l c of the secondary iron core, the air gap length g 0, the end tooth width w sth and the middle tooth width w st of the primary iron core, the slot width w sc of the primary iron core, the tooth height d sc of the primary iron core, the yoke thickness d se of the primary iron core, the length l s of the primary iron core and the overall iron core stack length l n .
[0054] The purpose of this application is to establish the mapping relationship between the structural parameters of a permanent magnet reluctance motor and the structural parameters of a 2D mirror image motor structure model, so that under the condition of knowing the slot-pole combination and structural parameters of the permanent magnet reluctance motor, the number of primary slots, the number of secondary teeth and the structural parameters of its 2D mirror image motor structure model can be quickly determined, thereby constructing a 2D mirror image motor structure model with electromagnetic characteristics similar to those of the original permanent magnet reluctance motor. The specific determination method of the parameters may include: 1. Determine the number of primary slots and the number of secondary teeth in the 2D mirror image motor structure model.
[0055] Analyze the slot-pole combination of the new permanent magnet reluctance motor. If it is not a symmetric structure, the number of primary slots in the 2D mirror image motor structure model is the same as the number of stator slots of the permanent magnet reluctance motor, and the total number of teeth in the secondary is 2 more than the number of rotor teeth of the permanent magnet reluctance motor (the middle tooth is counted as 1, and the end tooth is counted as 0.5); if it is a symmetric structure, after scaling down the number of stator slots and rotor teeth of the permanent magnet reluctance motor, then determine the number of primary slots and rotor teeth in the 2D mirror image motor structure model, where the number of primary slots is equal to the scaled-down number of stator slots, and the number of rotor teeth is 2 more than the scaled-down number of rotor teeth. In this embodiment, the slot-pole combination of the permanent magnet reluctance motor is 12 / 10, so it can be scaled down to 6 / 5. Therefore, the number of primary slots in the 2D mirror image motor structure model is 6, and the total number of secondary teeth is 7.

[0089] 6. Calculate the stacking length of the iron core of the 2D mirror motor structure model.
[0090] Since the mirror motor is a two-dimensional structure while the permanent magnet reluctance motor is a three-dimensional structure, there is the following conversion relationship between the stacking length of the iron core of the mirror motor and the axial length of the permanent magnet reluctance motor: 。 。
[0091] Based on the above parameter calculation results, a 2D mirror motor structure model can be generated. On the premise of knowing the structure parameters of the permanent magnet reluctance motor, the structure parameters of the 2D mirror motor structure model are obtained by conversion according to the above steps, and then the 2D mirror motor structure model is established. Then, the primary iron core material and secondary iron core material of the 2D mirror motor structure model are respectively corresponding to the stator iron core material and rotor iron core material of the permanent magnet reluctance motor. As an example, the winding is set to copper, and the material of the U-shaped supermagnet is set to silicon steel with a relative permeability of more than 100,000. Then, the primary winding of the 2D mirror motor structure model is set. The number of winding turns is the same as that of the permanent magnet reluctance motor, and the winding arrangement still adopts the three-phase overlapping winding same as that of the conventional linear motor, but the conduction directions of the upper winding and the lower winding on the primary iron core are opposite, as Figure 8 shown, which is the winding schematic diagram of the 2D mirror motor structure model in this embodiment. Finally, by setting the motion domain and boundaries, the 2D mirror motor structure model of the new permanent magnet reluctance motor can be obtained.
[0092] Based on the established 2D mirror motor structure model and using the 2D finite element method to calculate the no-load back electromotive force, cogging torque and rated torque of the motor, and comparing with the results of the permanent magnet reluctance motor analyzed by the 3D finite element method, the results shown in Figures 9 to 12 can be obtained, where Figure 9 is the comparison schematic diagram of the calculation results of the no-load back electromotive force of the permanent magnet reluctance motor and the 2D mirror motor, Figure 10 is the comparison schematic diagram of the calculation results of the cogging torque of the permanent magnet reluctance motor and the 2D mirror motor, Figure 11 is the comparison schematic diagram of the calculation results of the average torque of the permanent magnet reluctance motor and the 2D mirror motor. FromFigures 9 to 11 It can be seen that the calculation accuracies of the no-load back electromotive force, cogging torque and average torque of the 2D mirror motor can reach 92.5%, 83.3% and 98.6% of those of the original permanent magnet reluctance motor, respectively. Therefore, it can be used to replace the 3D model of the original permanent magnet reluctance motor for electromagnetic characteristic analysis.
[0093] Based on the in-depth analysis of the working principle and magnetic circuit characteristics of the axial-radial hybrid magnetic circuit motor, this application proposes a method for establishing the 2D mirror motor structure model of the axial-radial hybrid magnetic circuit motor, which is used for quickly and accurately calculating the key performance parameters of this type of motor.
