[0002] The cast aluminum rotor of a micro motor is a rotor manufactured by using aluminum casting technology and is widely used in various small motors, such as household appliances, toys, power tools, and small automation equipment, etc. The aluminum rotor has many advantages in micro motors due to its light weight, high conductivity, and good heat dissipation performance.

[0003] Currently, the cast aluminum rotors of micro motors usually lack a heat dissipation structure, and the commonly adopted heat dissipation method is mostly to additionally install a fan for heat dissipation on the motor. Although it can also achieve the heat dissipation effect, this also increases the heat dissipation cost of the motor, and the additionally installed fan is not convenient to disassemble during maintenance, resulting in a high maintenance cost. Therefore, it is necessary to design a cast aluminum rotor of a micro motor. Content of the Utility Model

[0007] To facilitate the pressing block to press down, as a cast aluminum rotor of a micro motor of the utility model, a fixing groove is opened on the upper surface of the fixed disk, and a threaded hole is opened on the inner bottom wall of the fixing groove.

[0008] To enable the sleeve rod to move, as a cast aluminum rotor of a micro motor of the utility model, a sleeve is fixedly connected to the outer surface of the copper plate, and a sleeve rod is arranged on the inner wall of the sleeve.

[0009] To enable the pressing block to be fixed, as a cast aluminum rotor of a micro motor of the utility model, a pressing block is fixedly connected to the upper surface of the sleeve rod.

[0010] To fix the fixed disk, as a cast aluminum rotor of a micro motor of the utility model, a screw is threadedly connected to the pressing block, and one end of the screw penetrates through the outer surface of the pressing block and extends to the inner surface of the pressing block.

[0011] In order to adjust the pressing block, as a cast aluminum rotor of a micro motor of the present utility model, the screw is in threaded connection with the threaded hole.

In the present utility model, through the settings of the rotor body, copper plate, through hole, metal rod, fixed disk and fan blade, in specific use, when the motor manufacturer uses this cast aluminum rotor to produce a motor, when the rotor body is rotating itself, the copper plate drives the fixed disk to rotate, and the fixed disk drives the fan blade to rotate. The fan blade can generate wind during rotation. At this time, the wind can flow through the through hole and dissipate heat from the operating rotor body, ensuring the service life of the rotor body and reducing the cost of additionally installing a fan for heat dissipation.

[0023] During specific use, when the rotor body 1 rotates itself, the fixing plate 5 is driven to rotate through the copper plate 2, and the fixing plate 5 drives the fan blade 6 to rotate. Wind power can be generated during the rotation of the fan blade 6. At this time, the wind power can flow through the through hole 3 and dissipate heat from the operating rotor body 1, ensuring the service life of the rotor body 1 and reducing the cost of additionally installing a fan for heat dissipation.

[0024] In this embodiment, a fixing groove 7 is provided on the upper surface of the fixing plate 5, and a threaded hole 8 is provided on the inner bottom wall of the fixing groove 7.

[0026] In this embodiment, a sleeve 9 is fixedly connected to the outer surface of the copper plate 2, and a sleeve rod 10 is provided on the inner wall of the sleeve 9.

[0027] During specific use, the sleeve rod 10 can slide up and down and rotate inside the sleeve 9. When the sleeve rod 10 slides up and down and rotates, it can drive the up and down position adjustment and rotation of the pressing block 11.

[0028] In this embodiment, a pressing block 11 is fixedly connected to the upper surface of the sleeve rod 10.

[0034] Working principle: During use, when the rotor body 1 rotates by itself, the copper plate 2 drives the fixed disk 5 to rotate, and the fixed disk 5 then drives the fan blade 6 to rotate. The fan blade 6 can generate wind during rotation. At this time, the wind can flow through the through hole 3 and dissipate heat from the operating rotor body 1, ensuring the service life of the rotor body 1 and reducing the cost of additionally installing a fan for heat dissipation. The sleeve rod 10 can slide up and down and rotate inside the sleeve 9. When the sleeve rod 10 slides up and down and rotates, it can drive the vertical position adjustment and rotation of the pressing block 11, adjust the pressing block 11 to the position corresponding to the fixed groove 7, and then thread-connect the screw 12 with the threaded hole 8 on the fixed disk 5, so as to fix the fixed disk 5 to the outer surface of the copper plate 2, thereby achieving convenient installation and disassembly of the fixed disk 5 and the fan blade 6, facilitating disassembly, maintenance and replacement of the fan blade 6 and the fixed disk 5.
