[0002] Generally, electromagnetic drive rotors are made of aluminum alloy. The rotors in this project are used in magnetic levitation systems, which have strict requirements on the rotor's weight, magnetic conductivity, and electrical conductivity. Summary of the Invention

[0003] The purpose of the present invention is to provide an electromagnetically driven carbon fiber rotor with the advantages of reliable structure, high safety, light overall weight, and reduced energy consumption during operation.

[0004] The object of the present invention is achieved as follows: an electromagnetically driven carbon fiber rotor, comprising a circular rotor bracket, a metal bushing nested in the center of the circular rotor bracket, a plurality of protrusions processed on the outer periphery of the circular rotor bracket, gaps for accommodating permanent magnets are formed between the protrusions, permanent magnets of the same size are arranged in the gaps, and a winding layer for fixing the permanent magnets is wrapped around the outer periphery of the circular rotor bracket.

[0005] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention adopts a metal bushing structure to support the external circular rotor bracket, thereby enhancing its structural strength, improving safety and reliability, and adopts a winding layer to wrap the permanent magnet, thereby reducing the weight of the rotor while ensuring structural reliability, thereby reducing energy consumption during the operation of the rotor.

[0006] In order to make the wrapping layer more secure when being fixed, bosses are processed on both sides of the protrusion to prevent the wrapping layer from falling off.

[0007] In order to enhance the reliability of the fixation between the metal bushing and the circular rotor bracket, the metal bushing is fixedly connected to the circular rotor bracket via the axial side baffle at the end. The outer periphery of the metal bushing is processed with a recessed platform that cooperates with the inner ring of the circular rotor bracket, and the axial side baffle is fixed to the end face of the metal bushing via bolts.

[0008] In order to further enhance the reliability of the fixation between the metal bushing and the circular rotor bracket, the inner ring of the circular rotor bracket is provided with a plurality of grooves, and the concave platform is processed with convex strips that match the grooves.

[0009] In order to further enhance the reliability of fixing the metal bushing to the circular rotor bracket, the cross section of the protrusion is trapezoidal, and the groove has the same shape as the protrusion.

[0010] In order to reduce the weight of the present invention, six fan-shaped weight-reducing holes are processed on the circular rotor bracket along its circumference.

[0011] In order to further reduce the weight of the present invention, the circular rotor bracket is made of carbon fiber material.

[0012] In order to further reduce the weight of the present invention, the winding layer is made of carbon fiber material. BRIEF DESCRIPTION OF THE DRAWINGS
