Description

Technical Field

[0001] This invention relates to the field of ceiling fan motor technology, specifically to an optimized winding for a ceiling fan motor. Background Technology

[0002] Currently, most ceiling fan motors on the market, especially those using three-phase windings, employ traditional winding wiring and connection methods. Traditional winding methods typically lead multiple taps or ends of each phase winding directly to terminals on the outside of the motor housing, resulting in a large number of leads and complex wiring. This not only increases the difficulty and clutter of internal wiring, occupies valuable internal space, and hinders the miniaturization and compact design of the motor structure, but also increases manufacturing costs and installation time due to the excessive number of terminals.

[0003] In addition, traditional wiring methods are less flexible and less compatible with external drives or controllers. When it is necessary to match with various intelligent controllers or frequency converters, additional adapter circuits or design modifications are often required, which limits the versatility and maintainability of the motor.

[0004] Therefore, this application proposes an optimized winding for a ceiling fan motor with a simpler structure, clearer wiring, and stronger compatibility. Summary of the Invention

[0005] (a) Technical problems to be solved The technical problem to be solved by the present invention is that the existing technology of ceiling fan motors has many winding leads, complicated wiring, low internal space utilization, poor compatibility with external controllers, and high manufacturing cost.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an optimized winding of a ceiling fan motor, comprising: A stator core, wherein a plurality of stator teeth are evenly distributed along the circumference of the stator core, and the stator teeth form a winding groove between them; The three-phase windings are embedded in the slots of the stator core and include a U-phase winding, a V-phase winding and a W-phase winding. Each phase winding has two independent leads, namely the start end and the end end; The tail ends of the U-phase winding, the V-phase winding, and the W-phase winding are electrically connected to each other at the ends of the stator core, forming a neutral point. The beginning ends of the U-phase winding, the V-phase winding, and the W-phase winding are respectively used as three independent external connection terminals.

[0007] As an improvement, the stator core is made of stacked annular silicon steel sheets and is installed inside the ceiling fan motor housing.

[0008] As an improvement, the rotor passes coaxially through the inside of the stator core, and the rotor passes through the ceiling fan motor housing and is connected to the ceiling fan motor housing by a bearing.

[0009] As an improvement, the three-phase winding is a symmetrically distributed star winding with the same number of turns and wire diameter.

[0010] As an improvement, the first end of the three-phase winding is connected to the external wiring terminal via a terminal block or terminal block fixed to the ceiling fan motor housing.

[0011] As an improvement, the neutral point is connected to the winding end of the stator core by welding, crimping, or using an insulating terminal cap.

[0012] (III) Beneficial Effects The advantages of this invention compared to the prior art are: Simplified structure and high space utilization: By connecting the ends of the three-phase windings into a neutral point inside the motor, the number of wires leading to external terminals is greatly reduced. This makes the internal wiring of the motor neater and more organized, effectively saving internal space and facilitating a more compact and lightweight motor design.

[0013] Clear wiring and high standardization: The standard star connection and only three external terminals (U, V, W) make production, installation, and maintenance extremely simple and uniform. Workers do not need to identify complex wiring sequences, reducing wiring error rates and improving production efficiency and product consistency. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] As attached Figure 3 Appendix Figure 4 and attached Figure 5 As shown, an optimized winding for a ceiling fan motor includes: A stator core 1 has multiple stator teeth evenly distributed along its circumference, and the stator teeth form a winding groove. The stator core 1 is made of stacked annular silicon steel sheets and is installed inside the ceiling fan motor housing 3.

[0022] The rotor 4 passes coaxially through the stator core 1, and the rotor 4 passes through the ceiling fan motor housing 3 and is connected to the ceiling fan motor housing 3 by a bearing.

[0023] As attached Figure 1 and attached Figure 2 As shown, the three-phase winding 2 is a symmetrically distributed star winding with the same number of turns and wire diameter. The three-phase winding 2 is embedded in the winding slot of the stator core 1 and includes a U-phase winding, a V-phase winding and a W-phase winding. Each phase winding has two independent leads, namely the start end and the end end; The tail ends (u1) of the U-phase winding, the tail ends (v1) of the V-phase winding, and the tail ends (w1) of the W-phase winding are electrically connected to each other at the ends of the stator core 1, forming a neutral point (N). The beginning of the U-phase winding (U1), the beginning of the V-phase winding (V1), and the beginning of the W-phase winding (W1) are respectively used as three independent external terminals (U, V, W).

[0024] The first end (U1, V1, W1) of the three-phase winding is connected to the external wiring terminals (U, V, W) through a terminal block or wiring plate fixed on the ceiling fan motor housing 3.

[0025] The neutral point (N) is connected to the winding end of the stator core 1 by welding, crimping, or insulating terminal caps.

[0026] The specific usage method is as follows: During the final assembly of the motor, the windings are wound and connected internally in the manner described above to form the neutral point N, and the three wires U1, V1, and W1 are connected to the U, V, and W terminals of the housing.

[0027] When using this ceiling fan motor, users or installers only need to connect the external power cord or the controller's output cord to the three terminals U, V, and W clearly marked on the motor housing.

[0028] Because it adopts a standard star connection and three-wire interface, this motor can be directly used with mainstream single-phase or three-phase ceiling fan speed controllers, smart home RF / Wi-Fi control modules, and DC brushless drivers on the market without any adapters or modifications.
