[0002] In industrial automation, precision manufacturing, and intelligent equipment, stepper motors are core components for achieving precise drive and positioning control. They are widely used in critical areas such as CNC machine tool feed systems, conveyor belt speed control in automated production lines, and precision instrument table positioning. By receiving pulse signals, they achieve precise angle and displacement control, ensuring that mechanical components operate stably along preset trajectories, such as tool feed during machine tool processing and part gripping and positioning in automated assembly. The stable operation of stepper motors directly affects the processing accuracy, operating efficiency, and reliability of equipment, and is a crucial foundation for ensuring the efficient operation of various automated equipment. However, existing stepper motors generally suffer from poor heat dissipation. In continuous high-load operation scenarios, the internal windings and iron core of the stepper motor will generate a lot of heat. Traditional motors mostly rely on simple casings for natural heat dissipation or small fans for auxiliary heat dissipation, resulting in inefficient heat dissipation structures.

[0015] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0016] To address the problems existing in the background technology, this application proposes the following technical solution: a long-life stepper motor based on heat dissipation efficiency enhancement technology, comprising a motor body 1, an outer casing 3, a heat dissipation component, and a water-cooling component; the outer casing 3 is disposed on the outside of the motor body 1; the heat dissipation component includes a heat sink 13 and a fan 14; the outer casing 3, covering the outside of the motor body 1, not only protects the motor body 1 from external dust and impacts, but also forms a closed heat dissipation space with the motor body 1, providing a mounting base for the heat dissipation component and the water-cooling component. The heat dissipation component and the water-cooling component work together, significantly improving heat dissipation efficiency through a combination of air cooling and liquid cooling.

[0017] In this embodiment, the water-cooling assembly includes a water tank 4, a delivery pipe 8, and a water pump 10. A heat dissipation plate 13 is fixedly connected to the water tank 4, with one end extending to the outside of the water tank 4. The top of the heat dissipation plate 13 is provided with multiple sets of heat dissipation slots. A fan 14 is fixedly connected to the heat dissipation plate 13. Multiple sets of spacers 2 are fixedly connected between the outer cover 3 and the motor body 1, forming a heat dissipation channel between the spacers 2. Fixing strips 5 are used to divide the spacers 2 into segments, thus breaking the heat dissipation channel. Fixing strips 5 are fixedly connected to the spacers 2. The water tank 4 stores coolant, the water pump 10 provides power for the coolant circulation, and the delivery pipe 8 accurately delivers the coolant to the heat dissipation area. The heat dissipation plate 13 extends to the outside of the water tank 4, and the heat dissipation slots on the top increase the contact area with the air. Combined with the fan 14, it accelerates the airflow, quickly removing the heat absorbed by the coolant and achieving coolant cooling circulation. The partition strip 2 between the outer cover 3 and the motor body 1 forms an independent heat dissipation channel. The fixing strip 5 divides the channel to prevent the coolant from flowing randomly in the channel, ensuring that each segment can dissipate heat evenly and preventing local overheating of the motor body 1.

[0018] In this embodiment, the outer casing 3 and the corresponding fixing strip 5 in the water tank 4 are respectively provided with a first through hole 6 and a second through hole 7 on both sides. The output end of the water pump 10 is fixedly connected to a delivery pipe 8, and one end of the delivery pipe 8 is fixedly connected to multiple sets of branch pipes 9. The branch pipes 9 are fixedly connected to the first through hole 6. The first through hole 6 and the second through hole 7 serve as the inlet and outlet of the coolant, respectively, to ensure that the coolant circulates along a preset path. The delivery pipe 8 is connected to the first through hole 6 through the branch pipes 9, so that the coolant can be evenly distributed to each heat dissipation channel, ensuring that all parts around the motor can be fully cooled, avoiding heat dissipation dead zones caused by uneven coolant distribution, and improving the overall heat dissipation effect.

[0019] In this embodiment, one end of the spacer 2 is fixedly connected to the outer wall of the motor body 1, and the other end is fixedly connected to the inner wall of the outer cover 3. The spacer 2 is distributed circumferentially along the motor body 1, and heat dissipation channels are formed between adjacent spacer 2. The two ends of the spacer 2 are connected to the motor body 1 and the outer cover 3 respectively, which not only enhances the connection stability between the outer cover 3 and the motor body 1, but also forms multiple independent heat dissipation channels through circumferential distribution, so that the coolant can flow evenly along the surface of the motor body 1, fully cover the heat dissipation area of ​​the motor body 1, maximize the contact area, and improve the heat exchange efficiency.

[0020] In this embodiment, a baffle 11 is also fixedly connected inside the water tank 4. The baffle 11 has an L-shaped structure and separates the first through hole 6 and the second through hole 7. There is a water outlet gap 12 between the baffle 11 and the water tank 4. The L-shaped baffle 11 separates the first through hole 6 (coolant inlet) and the second through hole 7 (coolant outlet) inside the water tank 4, preventing the low-temperature coolant that has just entered the water tank 4 from directly mixing with the high-temperature coolant returning from the heat dissipation channel, ensuring that the high-temperature coolant flows through the heat dissipation plate 13 for cooling first. The water outlet gap 12 provides a channel for the high-temperature coolant to flow to the heat dissipation plate 13, ensuring that the cooling process proceeds in an orderly manner and improving the cooling efficiency of the coolant.

[0021] In this embodiment, a controller is also included. The controller is electrically connected to the water pump 10 and the fan 14, respectively. A temperature sensor is provided on the outer wall of the motor body 1, and the temperature sensor is electrically connected to the controller. The controller controls the start and stop of the water pump 10 and the fan 14 based on the detection data of the temperature sensor. The temperature sensor monitors the motor temperature in real time, and the controller intelligently adjusts the start and stop of the water pump 10 and the fan 14 based on the temperature data: it stops operating when the temperature is low to save energy, and automatically starts when the temperature rises to enhance heat dissipation. This on-demand adjustment method avoids energy waste and ensures that the motor body 1 always operates within a suitable temperature range, reducing the wear and tear on the components of the motor body 1 caused by high temperatures and further extending its service life.

[0022] The usage method of this embodiment is as follows: When in use, the water pump 10 is started, and the water pump 10 draws out the coolant in the water tank 4 and delivers it to the first through hole 6 through the delivery pipe 8 and the branch pipe 9. After entering the heat dissipation channel, the coolant absorbs heat from the motor body 1 and then enters the vertical interior through the second through hole 7 and flows out through the water outlet gap 12, contacting the heat dissipation plate 13. The fan 14 dissipates heat from the heat dissipation plate 13, thereby cooling the coolant. The cooled coolant is then drawn out again by the water pump 10.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
