Description

Technical Field

[0001] This utility model specifically relates to the field of motor winding technology, and more specifically to a stator winding structure resistant to high and low temperatures. Background Technology

[0002] The stator winding of a micro motor refers to the coil winding assembly installed in the slots of the motor stator core. It is one of the key components of the motor. Its main function is to generate a magnetic field through current, thereby interacting with the rotor to realize the energy conversion and mechanical movement of the motor. In order to prevent current leakage between different coils or between the coils and the stator core, insulating materials are required.

[0003] However, in practice, it has been noted that temperature has a significant impact on the winding structure of motors, especially at high temperatures. Increased temperature causes the winding material to expand, and as the temperature rises, the hardness of the winding material decreases. This decrease in hardness may make the winding more prone to deformation, thereby changing the shape and spatial position of the winding. In contrast to the expansion at high temperatures, low temperatures cause the winding material to contract. Gaps may form between the winding and the stator slots due to contraction, which can easily lead to displacement during motor operation, thus affecting the magnetic field distribution and electrical performance of the motor. Utility Model Content

[0004] The purpose of this invention is to provide a high and low temperature resistant stator winding structure. The winding frame is surrounded by a ring-shaped array of heat dissipation holes, which, together with an adjustable and switchable heat sink at the bottom of the casing, allow for control of the internal temperature of the winding during operation. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high and low temperature resistant stator winding structure includes a metal shell, an upper winding frame and a lower winding frame are respectively placed on the inner side of the metal shell, and a spacer positioning frame is also provided between the upper winding frame and the lower winding frame. The ends of the metal casing are respectively provided with trapezoidal heat dissipation holes and circular heat dissipation holes in a ring array, and the trapezoidal heat dissipation holes and circular heat dissipation holes are spaced apart from each other. Each trapezoidal heat dissipation hole has an integrally provided bent bracket facing the inside of the metal casing, and a rotating baffle plate is movably connected to the bent bracket.

[0006] As a further technical solution of this utility model, the rotating barrier is attached to the inner end of the metal shell, and the bent bracket passes through the inner side of the rotating barrier. The rotating barrier has corresponding through holes corresponding to the trapezoidal heat dissipation holes and the circular heat dissipation holes.

[0007] As a further technical solution of this utility model, the side of the rotating barrier is integrally provided with a switch lever, and the side of the metal shell is also provided with a sliding groove corresponding to the switch lever, and the switch lever extends through the sliding groove to the side of the metal shell.

[0008] As a further technical solution of this utility model, the upper winding frame and the lower winding frame are respectively provided with heat dissipation holes and ventilation holes in a rectangular array, and the bottom of the lower winding frame is in contact with the bending bracket.

[0009] As a further technical solution of this utility model, the spacer positioning frame has two symmetrically arranged partitions, and each partition has a positioning bent plate arranged in a ring array on its side, and the positioning bent plate is inserted and cooperated with the upper winding frame and the lower winding frame.

[0010] As a further technical solution of this utility model, the end of the partition away from the positioning bend is provided with a positioning hole and a positioning protrusion, and the positioning hole and positioning protrusion are staggered and distributed, and the positioning protrusions in two adjacent partitions are inserted into the positioning hole in another partition.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a switch to rotate a rotating barrier plate, adjusting the position of the corresponding through hole on the rotating barrier plate. By adjusting the relative position between the corresponding through hole and the trapezoidal and circular heat dissipation holes, the opening size of the heat dissipation port is adjusted, thereby controlling the heat dissipation capacity and regulating the temperature of the upper and lower winding frames during operation to prevent excessively high or low temperatures. In this invention, the heat dissipation holes on the upper winding frame and the ventilation holes on the lower winding frame can increase the airflow, so that the temperature around the upper and lower winding frames can be balanced. Furthermore, since the lower winding frame is close to the heat dissipation port, it can dissipate heat more easily, thereby further controlling the temperature of the upper and lower winding frames during operation. This invention uses a spacer positioning frame to separate the upper winding frame and the lower winding frame, preventing the two sets of windings from interfering with each other. The positioning protrusions arranged in a ring array in the spacer positioning frame can play a positioning role, ensuring the relative position between the upper winding frame and the lower winding frame and preventing movement.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-8 This utility model provides a high and low temperature resistant stator winding structure, including a metal shell 2, an upper winding frame 3 and a lower winding frame 4 respectively placed on the inner side of the metal shell 2, and a spacer positioning frame 5 is also provided between the upper winding frame 3 and the lower winding frame 4. The ends of the metal casing 2 are respectively provided with trapezoidal heat dissipation holes 21 and circular heat dissipation holes 22 in a ring array, and the trapezoidal heat dissipation holes 21 and circular heat dissipation holes 22 are spaced apart from each other. Each trapezoidal heat dissipation hole 21 is integrally provided with a bent bracket 23 facing the inside of the metal casing 2, and a rotating baffle plate 6 is movably connected to the bent bracket 23.

[0023] In this embodiment, the rotating barrier 6 is attached to the inner end of the metal shell 2, and the bent bracket 23 passes through the inner side of the rotating barrier 6. The rotating barrier 6 has corresponding through holes 61 that correspond to the trapezoidal heat dissipation hole 21 and the circular heat dissipation hole 2.

[0024] Furthermore, the rotating barrier plate 6 has an integrally formed switch lever 62 on its side, and the metal housing 2 also has a groove 24 corresponding to the switch lever 62 on its side, and the switch lever 62 extends through the groove 24 to the side of the metal housing 2.

[0025] By adopting the above technical solution, the rotating barrier plate 6 is rotated by the switch lever 62, and the position of the corresponding through hole 61 on the rotating barrier plate 6 is adjusted. By adjusting the relative position between the corresponding through hole 61 and the trapezoidal heat dissipation hole 21 and the circular heat dissipation hole 22, the opening size of the heat dissipation port is adjusted, thereby controlling the heat dissipation capacity and regulating the temperature of the upper winding frame 3 and the lower winding frame 4 during operation to prevent the temperature from being too high or too low.

[0026] Furthermore, the upper winding frame 3 and the lower winding frame 4 are respectively provided with heat dissipation holes 31 and ventilation holes 41 in a rectangular array on both sides, and the bottom of the lower winding frame 4 is in contact with the bent bracket 23.

[0027] By adopting the above technical solution, the heat dissipation holes 31 opened on the upper winding frame 3 and the ventilation holes 41 opened on the lower winding frame 4 can increase the airflow, so that the temperature around the upper winding frame 3 and the lower winding frame 4 can be balanced. Furthermore, since the lower winding frame 4 is close to the heat dissipation port, it can dissipate heat more easily, thereby further controlling the temperature of the upper winding frame 3 and the lower winding frame 4 during operation.

[0028] Furthermore, the spacer positioning frame 5 has two symmetrically arranged partitions 51, and each partition 51 has a positioning bent plate 52 arranged in a ring array on its side, and the positioning bent plate 52 is inserted and engaged with the upper winding frame 3 and the lower winding frame 4.

[0029] More specifically, the end of the partition 51 away from the positioning curved plate 52 is provided with a positioning hole 53 and a positioning protrusion 54, and the positioning hole 53 and the positioning protrusion 54 are staggered and distributed, and the positioning protrusion 54 in two adjacent partitions 51 are inserted into the positioning hole 53 in another partition 51.

[0030] By adopting the above technical solution, the upper winding frame 3 and the lower winding frame 4 are separated by the spacer positioning frame 5 to prevent the two windings from interfering with each other. In addition, the positioning protrusions 54 arranged in a ring array in the spacer positioning frame 5 can play a positioning role, ensuring the relative position between the upper winding frame 3 and the lower winding frame 4 and preventing movement.

[0031] Furthermore, the side of the metal shell 2 is provided with a through groove, and the ends of the upper winding frame 3 and the lower winding frame 4 extend through the through groove to the side of the metal shell 2. The wires in the upper winding frame 3 and the lower winding frame 4 are respectively fixedly connected to the side of the upper winding frame 3 and the lower winding frame 4.

[0032] Furthermore, a central shaft 1 is fixedly connected to the inner side of the metal shell 2, and the end of the central shaft 1 passes through the upper winding frame 3 and the lower winding frame 4 and is fixedly connected to the bottom of the metal shell 2.

[0033] The working principle of this utility model is as follows: In use, firstly, the upper winding frame 3 and the lower winding frame 4 are installed inside the metal casing 2. Then, the rotating baffle 6 is rotated using the switch lever 62 to adjust the position of the corresponding through hole 61 on the rotating baffle 6. By adjusting the relative position between the corresponding through hole 61 and the trapezoidal heat dissipation hole 21, the size of the heat dissipation opening and the switch are controlled. When the internal temperature is high, the corresponding through hole 61 can be adjusted to completely overlap with the trapezoidal heat dissipation hole 21, ensuring heat dissipation inside the metal casing 2. Furthermore, the corresponding heat dissipation holes 31 on the upper winding frame 3 and the lower winding frame 4... The vent 41 allows airflow between the upper and lower parts of the metal casing 2, resulting in a more uniform temperature inside the metal casing 2. Finally, the internal heat is promptly discharged through the fully opened heat dissipation vents. When the temperature is low, rotating the rotating baffle 6 causes the corresponding through holes 61 and trapezoidal heat dissipation holes 21 to be staggered, completely closing the heat dissipation vents. The temperature generated by the windings in the upper winding frame 3 and lower winding frame 4 during operation is used to raise the temperature. Furthermore, the corresponding heat dissipation holes 31 and vent holes 41 on the upper winding frame 3 and lower winding frame 4 can achieve a certain temperature balance, thereby improving the high and low temperature resistance of the winding structure.
