Description

Technical Field

[0001] This utility model relates to the technical field of three-phase motor winding structure, specifically a three-phase motor winding structure. Background Technology

[0002] Three-phase motors are a common and widely used type of electric motor. They use three-phase alternating current (AC) as their driving energy. The main characteristics of three-phase motors are simple structure, stable operation, high efficiency, and large power output capability. The basic principle of a three-phase motor is that the three-phase AC power supply generates a rotating magnetic field through the stator, which in turn drives the rotor to rotate. Common three-phase motors include asynchronous motors (also known as induction motors) and synchronous motors. Asynchronous motors are the most common type of three-phase motor. There is no direct electrical connection between the rotor and stator. When three-phase power is applied to the stator coils, a rotating magnetic field is generated. The rotor, under the influence of this magnetic field, generates an induced electromotive force, causing it to rotate. The speed of an asynchronous motor is slightly lower than the synchronous speed; this speed difference is called slip. Asynchronous motors are commonly used in industrial and household appliances. In the production of three-phase motors, workers need to perform winding processing on the internal coils.

[0003] However, existing three-phase motor winding structures typically only allow for single-turn winding of a single coil specification simultaneously during use, resulting in low winding efficiency and hindering rapid coil production. Therefore, they do not meet current requirements, and we propose a new three-phase motor winding structure. Utility Model Content

[0004] The purpose of this utility model is to provide a three-phase motor winding structure to solve the problem that the three-phase motor winding structure mentioned in the background art can usually only perform single-turn winding of a coil of one specification simultaneously, resulting in low winding efficiency and affecting the rapid production of coils.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-phase motor winding structure, including a support plate:

[0006] A rotating bracket is rotatably mounted on the upper end of the front end face of the support plate. Movable sliding shafts are provided on both sides inside the front end face of the rotating bracket. The movable sliding shafts are slidably connected to the rotating bracket via slots. A limit baffle is installed on the front end face of the rotating bracket and is fixedly connected to the rotating bracket. The movable sliding shafts are slidably connected to the limit baffle via slots. A winding pagoda roller is rotatably mounted on the front end face of the movable sliding shaft. A winding partition is installed on the outside of the winding pagoda roller, and the winding partition is threadedly connected to the winding pagoda roller.

[0007] A wire roller is rotatably mounted on the lower end of the support plate. Wire coils are provided at the front end of the wire roller, and copper wire is provided on the outside of the wire coils. A counterweight is installed at the rear end of the wire roller and is rotatably connected to the wire roller. A fixing screw is installed on the outside of the counterweight and is threadedly connected to the support plate.

[0008] Preferably, a drive motor is installed at the upper end of the rear end face of the support plate, the drive motor is connected to the support plate by screws, and the drive motor is connected to the rotating bracket by a coupling.

[0009] Preferably, a stabilizing base plate is installed at the lower end of the support plate, and the stabilizing base plate is welded to the support plate.

[0011] Preferably, adjustment brackets are installed on both sides of the front end face of the rotating bracket, and the adjustment brackets are welded to the rotating bracket.

[0012] Preferably, the adjusting bracket is internally provided with a bidirectional lead screw, which is rotatably connected to the adjusting bracket via a bearing, and the bidirectional lead screw is connected to the movable slide shaft via a ball screw nut pair.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model can separate coils by installing winding partitions to prevent coils of different specifications from tangling together, thus ensuring the winding effect of the device. Installing winding pagoda rollers can utilize their different external diameters to enable the device to synchronously wind coils of different specifications, thereby achieving the purpose of rapid coil production and improving production efficiency. Installing counterweights can balance part of the weight of the wire coils, making the center of the device closer to the center position and enhancing the stability of the device.

[0015] 2. This utility model can limit the counterweight by installing a fixed screw, preventing the counterweight from shaking and ensuring the stability of the device. Installing a bidirectional screw makes it easy for the operator to adjust the distance between the two winding tower rollers, thereby enabling the device to produce more coils of different specifications and enhancing the flexibility of the device.

Movable sliding shafts 4 are provided on both sides of the inner surface of the front face of the rotating bracket 2. The movable sliding shafts 4 are slidably connected to the rotating bracket 2 via slots. A limit baffle 7 is installed on the front face of the rotating bracket 2 and is fixedly connected to the rotating bracket 2. The movable sliding shafts 4 and the limit baffle 7 are slidably connected via slots. A winding pagoda roller 5 is rotatably mounted on the front face of the movable sliding shaft 4. A winding partition 6 is installed on the outside of the winding pagoda roller 5. The winding partition 6 can separate the coils, preventing coils of different specifications from tangling together and ensuring the winding effect of the device. The winding partition 6 and the winding pagoda roller 5 are connected by threads. The installation of the winding pagoda roller 5 allows the device to synchronously wind coils of different specifications using its external diameters, thereby achieving the purpose of rapid coil production and improving production efficiency.

[0024] The wire roller 15 is rotatably mounted on the lower end of the support plate 1. Wire coils 12 are provided at the front end of the wire roller 15, and copper wire is provided on the outside of the wire coils 12. A counterweight 11 is installed at the rear end of the wire roller 15. The counterweight 11 can balance part of the weight of the wire coils 12, making the center of the device closer to the center position and enhancing the stability of the device. The counterweight 11 is rotatably connected to the wire roller 15. A fixing screw 10 is installed on the outside of the counterweight 11. The fixing screw 10 can limit the counterweight 11, prevent the counterweight 11 from shaking, and ensure the stability of the device. The fixing screw 10 is connected to the support plate 1 by threads.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A drive motor 9 is installed on the upper end of the rear face of the support plate 1.

The bidirectional lead screw 8 is rotatably connected to the adjusting bracket 3 by bearings. The bidirectional lead screw 8 is connected to the moving slide shaft 4 by a ball screw nut pair.

[0026] Working Principle: During use, the operator rotates the bidirectional lead screw 8 according to production needs to adjust the spacing between the two winding pagoda rollers 5. Then, copper wire is pulled out from the wire coil 12 and wound around the upper end of the winding pagoda rollers 5. The drive motor 9 then rotates the rotating bracket 2, ensuring the copper wire is evenly wound around the outside of the two winding pagoda rollers 5. After the coil winding is complete, the operator removes the winding separator 6 and the coil. The winding separator 6 separates the coils, preventing coils of different specifications from tangling and ensuring the winding effect. The winding pagoda rollers 5 utilize their external... The same diameter external winding allows the device to synchronously wind coils of different specifications, thereby achieving the goal of rapid coil production and improving production efficiency.
