Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, specifically an electromagnetically driven carbon fiber rotor. Background Technology

[0002] In the field of electromagnetic drives, traditional rotors have several shortcomings. The core structure of traditional rotors is often relatively simple, which is not conducive to the optimized distribution and effective utilization of the magnetic field, thus limiting the efficiency and performance of the motor. Furthermore, the magnet fixing method of traditional rotors is not reliable enough; at high speeds, the magnets may shift or even fall off, posing a safety hazard. In addition, traditional rotors are relatively heavy, increasing the overall burden on the motor and hindering improvements in energy efficiency and response speed. Therefore, those skilled in the art have provided an electromagnetically driven carbon fiber rotor to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide an electromagnetically driven carbon fiber rotor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electromagnetically driven carbon fiber rotor includes a rotor shaft, an iron core, and magnets. A limiting spline is fixedly connected to the surface of the rotor shaft. The iron core consists of an end plate and a support plate. The support plates are fixedly connected between the two end plates and are evenly arranged. A spline groove is formed on the surface of the end plate. The iron core is sleeved on the outside of the rotor shaft through the spline groove and the limiting spline. A magnet is sleeved on the outer wall of the iron core, and a protective sleeve is sleeved on the outer wall of the magnet.

[0006] Furthermore, the support plates are inclined, and magnetic conductors are detachably connected between the support plates.

[0007] Furthermore, the surface of the magnet is provided with evenly arranged winding slots, and the inner sidewall of the winding slots is wound with rotor windings.

[0008] Furthermore, the magnet is a neodymium iron boron permanent magnet.

[0009] Furthermore, the sheath is made of carbon fiber material.

[0010] By adopting the above technical solution

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The iron core support plates are inclined and detachably connected with magnetic conductors to form a composite magnetic structure. This structural design can effectively guide and optimize the distribution of the magnetic field, enhance the strength and uniformity of the magnetic field, reduce magnetic leakage, reduce torque pulsation, and improve the efficiency and performance of the motor. By adjusting the position and parameters of the magnetic conductors, the magnetic field can be precisely controlled according to different application requirements, so that the motor can maintain a good operating condition under various working conditions.

[0013] 2. The sheath made of carbon fiber material is significantly lighter than the traditional metal sheath. The lightweight design reduces the rotor's moment of inertia, allowing the motor to respond to control signals more quickly and improving the motor's dynamic performance and energy efficiency. At the same time, carbon fiber has the characteristics of high strength and low density, which can withstand the huge centrifugal force generated by the magnets when rotating at high speed, effectively preventing the magnets from shifting or falling off. This reliable fixing method improves the safety and stability of the rotor and reduces safety accidents caused by the loosening or falling off of the magnets. Attached Figure Description

In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] Please see Figures 1-4This utility model provides an embodiment of an electromagnetically driven carbon fiber rotor, comprising a rotor shaft 1, an iron core 2, and magnets 3. A limiting spline 101 is fixedly connected to the surface of the rotor shaft 1. The iron core 2 consists of end plates 201 and support plates 202. Evenly distributed support plates 202 are fixedly connected between the two end plates 201. Spline grooves 203 are formed on the surface of the end plates 201. The iron core 2 is sleeved on the outside of the rotor shaft 1 through the spline grooves 203 and the limiting spline 101. Magnets 3 are sleeved on the outer wall of the iron core 2, and a protective sleeve 4 is sleeved on the outer wall of the magnets 3. The support plates 202 are inclined, and a magnetic conductor is detachably connected between the support plates 202. Evenly distributed winding grooves 301 are formed on the surface of the magnets 3, and rotor windings 5 ​​are wound around the inner sidewalls of the winding grooves 301. When energized, the stator windings generate a rotating magnetic field, and the rotor shaft 1 is connected to the iron core 1 through the limiting spline 101. The core 2 is connected to prevent axial movement, allowing the core 2 to rotate synchronously with the rotor shaft 1. The rotating magnetic field interacts with the magnetic field of the magnet 3, generating an induced electromotive force and induced current in the rotor winding 5. According to Ampere's law, a current-carrying conductor in a magnetic field will experience a force, thereby generating a rotational torque in the rotor, driving the rotor shaft 1 to rotate, realizing the conversion of electrical energy into mechanical energy. The support plates 202 of the core 2 are inclined and detachably connected with magnetic conductors, forming a composite magnetic structure. This structural design can effectively guide and optimize the distribution of the magnetic field, enhance the strength and uniformity of the magnetic field, reduce leakage flux, reduce torque pulsation, and improve the efficiency and performance of the motor. By adjusting the position and parameters of the magnetic conductors, the magnetic field can be precisely controlled according to different application requirements, so that the motor can maintain a good operating state under various working conditions.

[0021] In this embodiment, the magnet 3 is a neodymium iron boron permanent magnet, and the sheath 4 is made of carbon fiber material. Compared with the traditional metal sheath 4, the sheath 4 made of carbon fiber material is much lighter. The lightweight design reduces the rotational inertia of the rotor, enabling the motor to respond to control signals more quickly and improving the dynamic performance and energy efficiency of the motor. At the same time, carbon fiber has the characteristics of high strength and low density, which can withstand the huge centrifugal force generated by the magnet 3 when rotating at high speed, effectively preventing the magnet 3 from shifting or falling off. This reliable fixing method improves the safety and stability of the rotor and reduces safety accidents caused by the loosening or falling off of the magnet 3.

[0022] When energized, the stator winding generates a rotating magnetic field. The rotor shaft 1 is connected to the iron core 2 through the limiting spline 101, so that the iron core 2 can rotate synchronously with the rotor shaft 1 to avoid axial movement. The rotating magnetic field interacts with the magnetic field of the magnet 3, generating an induced electromotive force and an induced current in the rotor winding 5. According to Ampere's law, a current-carrying conductor will be subjected to a force in a magnetic field, thereby generating a rotational torque in the rotor, driving the rotor shaft 1 to rotate, and realizing the conversion of electrical energy into mechanical energy.

[0023] The support plates 202 of the iron core 2 are inclined and detachably connected with magnetic conductors to form a composite magnetic structure. This structural design can effectively guide and optimize the distribution of the magnetic field, enhance the strength and uniformity of the magnetic field, reduce magnetic leakage, reduce torque pulsation, and improve the efficiency and performance of the motor. By adjusting the position and parameters of the magnetic conductors, the magnetic field can be precisely controlled according to different application requirements, so that the motor can maintain a good operating state under various working conditions. The sheath 4 made of carbon fiber material is much lighter than the traditional metal sheath 4. The lightweight design reduces the rotational inertia of the rotor, enabling the motor to respond to control signals more quickly and improving the dynamic performance and energy efficiency of the motor. At the same time, carbon fiber has the characteristics of high strength and low density, which can withstand the huge centrifugal force generated by the magnet 3 when rotating at high speed, effectively preventing the magnet 3 from shifting or falling off. This reliable fixing method improves the safety and stability of the rotor and reduces safety accidents caused by the loosening or falling off of the magnet 3.
