Technical Field

[0001] This utility model relates to the field of motor stator core technology, and in particular to an external rotor motor stator core. Background Technology

[0002] External rotor motors, as a type of high-efficiency motor, are widely used in various fields such as industry, home appliances, fans, and pumps. They are favored for their high power density, small size, and excellent cooling performance. One of the core components of an external rotor motor is the stator core, whose design directly affects the motor's efficiency, stability, and lifespan. Traditional stator core designs often suffer from problems such as low magnetic field utilization and structural instability. Therefore, improving the performance of the stator core, especially in external rotor motors, has become a pressing technical problem to be solved in the field of motor design.

[0003] Therefore, it is essential to invent a stator core for an external rotor motor. Utility Model Content

An external rotor motor stator core includes a base plate, an extension base, a connecting spindle, a connecting block, and stator electrodes. The extension base is fixedly mounted on the outer side of the base plate surface, and the connecting spindle is fixedly mounted on the inner side of the base plate surface. The connecting block is fixedly mounted on the outer surface of the extension base. The stator electrodes are mounted on the outer sides of the extension base and the connecting block.

[0005] The connecting spindle includes a connecting base plate, a supporting base tube, a connecting sleeve, and an anti-slip groove. The connecting base plate is fixedly installed on the inner side of the base plate surface, and the supporting base tube is fixedly installed on the surface of the connecting base plate. The connecting sleeve is slidably installed inside the supporting base tube, and the anti-slip groove is formed on the inner wall of the connecting sleeve.

[0006] The stator electrode includes a support housing, a mounting groove, a winding core, an electromagnetic coil, and a counterweight stabilizing block. The mounting groove is formed on the inner wall of the support housing, which is mounted on the outside of the extension base and the connecting block through the mounting groove. The electromagnetic coil is wound on the outside of the support housing, and the counterweight stabilizing block is slidably mounted in the gap between the mounting groove and the connecting spindle.

[0007] The entire connecting spindle is made of steel metal structure, and the connecting base plate is a circular metal plate that is connected and fixed to the base plate. The supporting base tube is a steel metal tube, and the coupling sleeve can be slidably installed or disassembled inside the supporting base tube. The anti-slip groove consists of several grooves parallel to the axial direction of the coupling sleeve.

[0008] After the stator electrode is connected to the extension substrate and the connecting block, a trapezoidal gap is left between the mounting groove and the connecting spindle, and the gap between the mounting groove and the connecting spindle is filled by a counterweight stabilizing block. The counterweight stabilizing block has different lengths and weights; the counterweight stabilizing block uses a characteristic weight as needed.

The connecting spindle helps to fix the stator electrodes and other components in their proper relative positions, ensuring the structural stability of the external rotor motor, reducing vibration, and improving the overall performance of the motor. Furthermore, the connecting spindle also bears the mechanical load, ensuring smooth operation of the motor during operation.

[0011] 2.

The electromagnetic coil is the core part of the motor that generates electromagnetic force; ③ Support function:

[0012] The support housing provides structural support for the stator electrodes, ensuring their stable position within the motor.

[0013] The support housing is also connected to the extension base and connecting block via mounting slots.

Through precise structural design and an electromagnetic system, it achieves efficient and stable operation of the external rotor motor. The base plate and extended base provide mechanical support, ensuring stable connection of all components and reducing vibration.
