[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1 、 Figure 2 and Figure 3 As shown, an electronic rotor mechanism of the present invention includes a rotating shaft 1 and a plurality of fixed steel sheets 2, which are slidably sleeved on the outer surface of the rotating shaft 1, and a spacer steel sheet 3 is slidably sleeved on the rotating shaft 1 between two adjacent fixed steel sheets 2. Both ends of the outer surface of the rotating shaft 1 are threadedly sleeved with fastening nuts 4, and opposite sides of the two fastening nuts 4 are tightly fitted with the fixed steel sheets 2 located at both ends of the rotating shaft 1. Threaded holes 5 are provided in the middle of both ends of the rotating shaft 1, and rotating shaft caps 6 are movably sleeved on both ends of the rotating shaft 1. The middle parts of the two rotating shaft caps 6 on the opposite sides are provided with insertion holes, and fastening bolts 7 are inserted in the two insertion holes, and the ends of the two fastening bolts 7 are respectively threadedly connected to the inside of the two threaded holes 5.

[0023] Among them, the fixed steel sheet 2 is made of silicon steel, and a number of winding grooves 8 are opened at equal arcs and equal intervals on the edge of the fixed steel sheet 2, and the number of winding grooves 8 is an even number. Setting a number of winding grooves 8 with an even number can facilitate winding. The fixed steel sheet 2 made of silicon steel has high magnetic permeability, and the hysteresis loss and eddy current loss are relatively small.

[0024] Among them, the outer surface of the rotating shaft 1 is provided with four slots 9 with equal arcs and equal intervals along the axial direction, and the surface of the inner ring of the fixed steel sheet 2 is fixed with four blocks with equal arcs and equal intervals. The four blocks are matched with the four slots 9. The cooperation between the blocks and the slots 9 can ensure that when the rotor rotates, the fixed steel sheet 2 and the rotating shaft 1 remain relatively fixed.

[0025] Among them, the surface of the inner ring of the spacer steel sheet 3 is also fixed with four blocks at equal arcs and intervals. The four blocks are matched with four slots 9. The cooperation between the blocks and the slots 9 can ensure that the spacer steel sheet 3 and the rotating shaft 1 remain relatively fixed when the rotor rotates.

[0026] Among them, the outer surfaces of the two rotating shaft caps 6 are both provided with key slots 10, and the inner surfaces of the two rotating shaft caps 6 are also fixed with a clamping block, which is matched with the clamping slot 9. The key slot 10 is provided to facilitate the use of a flat key to connect and fix the rotating shaft cap 6 to the external coupling.

[0027] Among them, rolling bearings 11 are fixedly provided at opposite ends of the outer surfaces of the two shaft caps 6. The provision of rolling bearings 11 can reduce the friction between the shaft caps 6 and the external electronic housing, thereby ensuring that the entire rotor can rotate easily.

[0028] Among them, the outer diameter of several spacer steel sheets 3 is smaller than the distance between the bottom of the winding groove 8 and the center of the fixed steel sheet 2, so as to avoid the spacer steel sheets 3 from hindering the winding, thereby facilitating the winding of the rotor.

[0029] Among them, the two fastening bolts 7 are both hexagon socket bolts, and the sockets are countersunk holes. The countersunk holes can ensure that the fastening bolts 7 can completely enter the inside of the sockets. In this way, after the installation is completed, the surface of the fastening bolts 7 and the end of the shaft cap 6 are in the same plane, avoiding obstacles to the installation of the coupling.

[0030] First, select a rotating shaft 1 of a specified length, and take out a corresponding number of fixed steel sheets 2 and spacer steel sheets 3. Then, several fixed steel sheets 2 and spacer steel sheets 3 are alternately sleeved on the outer surface of the rotating shaft 1. The outer surface of the rotating shaft 1 is provided with four slots 9 with equal arcs and equal spacing along the axial direction. The surface of the inner ring of the fixed steel sheet 2 is fixed with four blocks with equal arcs and equal spacing. The surface of the inner ring of the spacer steel sheet 3 is also fixed with four blocks with equal arcs and equal spacing. The cooperation of the blocks and the slots 9 can ensure that the fixed steel sheet 2 is fixed when the rotor rotates. The spacer steel sheet 3 and the rotating shaft 1 are kept relatively fixed. After the installation of the fixed steel sheet 2 and the spacer steel sheet 3 is completed, the two fastening nuts 4 are respectively bolted on the two ends of the rotating shaft 1 and tightened. The two fastening nuts 4 are squeezed to make several fixed steel sheets 2 and the spacer steel sheets 3 tightly arranged. Then the two rotating shaft caps 6 are respectively put on the two ends of the rotating shaft 1, and the rotating shaft 1 and the rotating shaft caps 6 are fixedly connected by the fastening bolts 7 and the threaded holes 5. The inner surfaces of the two rotating shaft caps 6 are also fixed with blocks. By tightening The fixing bolt 7 is fixed to the axial direction of the rotating shaft cap 6, and the rotating shaft cap 6 is fixed circumferentially by the cooperation of the clamping block and the clamping groove 9. This ensures that the rotating shaft cap 6 is completely fixed to the rotating shaft 1. Then, two rolling bearings 11 are fixedly sleeved on the surfaces of the two rotating shaft caps 6. The provision of rolling bearings 11 can reduce the friction between the rotating shaft cap 6 and the external electronic housing, thereby ensuring that the entire rotor can rotate easily. At this point, the assembly of the entire electronic rotor mechanism is completed. This electronic rotor mechanism is fixed to the surface of the rotating shaft 1 by a plurality of fixed steel sheets 2 and spacer steel sheets 3 alternately stacked and fixed. It can consume less material and effectively reduce the overall weight of the electronic rotor, thereby effectively reducing the overall weight of the electronic motor. At the same time, if it is necessary to produce electronic rotors of different lengths, it is only necessary to use rotating shafts 1 of different lengths. Then, by increasing or decreasing the number of fixed steel sheets 2 and spacer steel sheets 3, electronic rotors of different lengths can be produced. It can be applied to various models of electronic motors and has strong applicability.
