Description

Technical Field

[0001] This invention relates to the field of stator core processing technology, specifically to an integrated machine for impregnating and drying winding stator cores and its operating method. Background Technology

[0002] In the processing of motor winding stator core, in order to improve the rust resistance of the winding stator core, the surface of the winding stator core is painted or dipped in varnish. Traditional painting equipment has the problem that it is not easy to spray paint onto the inner surface of the winding stator core. The existing method is to dip the winding stator core in varnish, which can dip the surface of the winding stator core in varnish.

[0003] For example, the patent application number 201921662024.8 discloses a motor rotor impregnation equipment, which solves the problem of low impregnation efficiency. However, it has problems such as the paint not being able to enter the gap between silicon steel sheets under normal pressure, poor impregnation quality of winding stator core, and inconvenience in drying the motor stator after impregnation.

[0004] Based on this, the applicant proposes an integrated machine for impregnating and drying winding stator cores and its operating method. Summary of the Invention

[0005] The purpose of this invention is to address the problems of existing winding stator core impregnation and drying devices, such as the difficulty of the varnish entering the gaps between silicon steel sheets under normal pressure, poor varnish quality of the winding stator core, and inconvenience in drying the impregnated motor stator. This invention provides a winding stator core impregnation and drying integrated machine and its operating method, which has a reasonable structural design, can perform high-pressure impregnation of the winding stator core, produces high-quality varnish, and facilitates drying of the impregnated motor stator.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A winding stator core impregnation and drying integrated machine includes a varnish tank, a support plate, and an impregnation cylinder. A drive structure is located at the bottom of the varnish tank, and the support plate is movably connected to the drive structure. A connecting column is vertically mounted on the support plate, and a cover plate is located at the top of the connecting column. A heating fan and an agitator are mounted on the cover plate. The impregnation cylinder is movably mounted on the support plate, and the agitator extends into the cylinder. The winding stator core to be impregnated is placed into the impregnation cylinder. Under the action of the drive structure, the support plate drives the impregnation cylinder and the winding stator core inside into the varnish tank. The descending cover plate covers the varnish tank, allowing the winding stator core to dry completely. The stator core is impregnated in a sealed varnish tank. During the impregnation process, a heating fan can blow airflow into the varnish tank to increase the air pressure inside, allowing the stator core to undergo impregnation under high pressure. This enhances the impregnation efficiency and quality. After the stator core is impregnated, the support plate, driven by the drive structure, lifts the impregnation cylinder, removing the cylinder and the stator core from the varnish tank. The heating fan then dries the impregnated stator core, improving the drying efficiency and effect, thereby increasing the overall processing efficiency.

[0008] Preferably, the drive structure includes a drive motor and connecting screw rings, with the drive motor configured as a servo motor. A bearing is installed on the inner wall of the paint tank, and the drive motor is installed on the outer wall of the paint tank. A double-screw is installed on the drive motor, extending into the paint tank and inserting one end of the double-screw into the bearing. The connecting screw ring is sleeved on the double-screw, and a connecting plate is installed at the top of the connecting screw ring. A push rod is installed between the connecting plate and the connecting plate via a pin, and the other end of the push rod is movably connected to a support plate. The drive motor drives the double-screw to rotate forward or backward, and the two connecting screw rings on the double-screw move towards or away from each other. The fixing plate on the connecting screw ring drives the bottom end of the push rod to move via the pin, causing the top end of the push rod to push the support plate upward or downward. The support plate drives the varnish-impregnating cylinder and the cover plate to rise or fall, removing the varnish-impregnating cylinder from the paint tank or inserting it into the paint, facilitating the varnish-impregnating treatment of the winding stator core inside the varnish-impregnating cylinder and improving the varnish-impregnating efficiency of the winding stator core.

[0009] Preferably, the bottom of the support plate is provided with a fixing plate, and a fixing groove is provided on the fixing plate. Limiting rods are provided on both sides of the top of the push rod, and the limiting rods pass through the fixing groove. The fixing groove on the fixing plate can provide limiting space for the limiting rods, so that the limiting rods can smoothly push the support plate to rise or fall, thereby improving the stability of the support plate driving the paint dipping cylinder to rise or fall.

[0010] Preferably, the support plate is provided with a positioning cylinder and a through groove penetrating the upper and lower parts of the support plate. The bottom of the impregnation cylinder is provided with a positioning post. The positioning post is placed into the positioning cylinder, and the impregnation cylinder is configured to be replaceable on the support plate through the positioning post. Placing the positioning post at the bottom of the impregnation cylinder into the positioning cylinder on the support plate facilitates the quick placement of the impregnation cylinder on the support plate or the quick removal of the impregnation cylinder from the support plate, thereby improving the assembly efficiency of the impregnation cylinder. The through groove on the support plate can reduce the resistance encountered by the support plate during the process of entering the paint liquid, and also facilitates the quick return of excess paint liquid to the paint liquid tank during the drying process of the winding stator core, thereby reducing the waste of paint liquid.

[0011] Preferably, the impregnation cylinder is provided with drainage holes on its side wall and bottom. The varnish in the varnish tank flows into the impregnation cylinder through the drainage holes on the side wall and bottom of the impregnation cylinder to impregnate the winding stator core inside the impregnation cylinder. When the winding stator core inside the impregnation cylinder is dried, the excess varnish and airflow in the impregnation cylinder are quickly discharged from the drainage holes, which facilitates the rapid drying of the winding stator core, thereby improving the drying efficiency and drying quality of the winding stator core.

[0012] Preferably, the agitation structure includes a rotary motor and a rotary shaft. A bearing is provided on the cover plate, and the rotary shaft is mounted on the cover plate. A drive shaft is mounted on the rotary shaft, extending from below the cover plate. A drive wheel is mounted on the drive shaft. The rotary shaft passes vertically through the bearing and its bottom end extends into the impregnation tank. A stirring rod is mounted on the rotary shaft inside the impregnation tank. A driven wheel is mounted on the rotary shaft below the cover plate and connected to the drive wheel via a belt. The rotary motor drives the drive shaft and the drive wheel to rotate. The drive wheel drives the driven wheel to rotate via the belt. The driven wheel drives the rotary shaft and the stirring rod to rotate. The stirring rod agitates the winding stator core inside the impregnation tank, ensuring that the winding stator core is in full contact with the varnish or a heat-carrying airflow, thus performing thorough impregnation or drying treatment on the winding stator core and improving the impregnation and drying efficiency and quality of the winding stator core.

[0013] Preferably, the rotating shaft is a hollow structure, and an exhaust trough is provided on the side wall of the rotating shaft inside the impregnation tube. The heating fan is equipped with an air supply pipe, and a connecting pipe is provided on the air supply pipe. The connecting pipe extends into the rotating shaft from the top of the rotating shaft. The heating fan blows air into the hollow rotating shaft through the air supply pipe and the connecting pipe. The airflow flows into the impregnation tube through the exhaust trough, increasing the pressure in the varnish tank. This allows the winding stator core to be impregnated under high pressure, enhancing the impregnation quality of the stator core. The heating fan blows air into the hollow rotating shaft through the air supply pipe and the connecting pipe. The airflow flows into the impregnation tube through the exhaust trough on the rotating shaft. The airflow in the impregnation tube is discharged through the drain hole, drying the impregnated winding stator core in the impregnation tube, improving the drying efficiency and drying quality of the winding stator core.

[0014] Preferably, a sealing ring is provided between the connecting pipe and the inner wall of the rotating shaft. The sealing ring can prevent the airflow carrying heat that enters the rotating shaft from flowing out between the air supply pipe and the inner wall of the rotating shaft, so that the airflow carrying heat can enter the impregnation barrel to dry the impregnated winding stator core, thereby improving the drying efficiency and drying quality of the winding stator core.

[0015] An operating method for an integrated machine for impregnating and drying winding stator cores, the operating method comprising the following steps:

[0016] First: Move the integrated winding stator core impregnation and drying machine to a suitable location and check whether the circuit of the integrated winding stator core impregnation and drying machine is normal, and whether the drive motor, heating fan and rotary motor can work normally.

[0017] Second: Start the drive motor. The drive motor drives the double screw to rotate in the forward direction. The two connecting rings on the double screw move towards each other. The fixing plate on the connecting ring drives the bottom of the push rod to move through the pin shaft, so that the top of the push rod pushes the bearing plate upward. The bearing plate drives the paint dipping cylinder and the cover plate to rise, and removes the paint dipping cylinder from the paint tank.

[0018] Third: Inject paint into the paint tank, put the winding stator core that needs to be impregnated into the impregnation cylinder, start the drive motor, and make the drive motor drive the double screw to rotate in the opposite direction, so that the support plate moves the impregnation cylinder and the cover plate down. When the cover plate covers the paint tank, turn off the drive motor.

[0019] Fourth: The paint in the paint tank flows into the paint dipping cylinder through the drain holes on the side wall and bottom of the paint dipping cylinder, and the winding stator core inside the paint dipping cylinder is impregnated with paint.

[0020] Fifth: Start the rotary motor. The rotary motor drives the drive shaft and the drive wheel on the drive shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt. The driven wheel drives the rotary shaft and the stirring rod on the rotary shaft to rotate. The stirring rod stirs the winding stator core in the impregnation barrel, so that the winding stator core is in full contact with the varnish, and the winding stator core is fully impregnated.

[0021] Sixth: In order to enhance the impregnation effect of the winding stator core, a heating fan can be started during the impregnation process of the winding stator core. The heating fan blows air into the hollow rotating shaft through the air supply pipe. The air flows into the impregnation tank through the exhaust trough, increasing the pressure in the varnish tank, which allows the winding stator core to be impregnated under high pressure.

[0022] Seventh: After the stator core of the winding is impregnated with varnish, start the drive motor. The drive motor drives the double screw to rotate in the forward direction. The support plate drives the impregnation cylinder and cover plate to rise. The excess varnish in the impregnation cylinder flows out through the drain hole. The varnish that falls onto the support plate flows back to the varnish tank through the through groove. The heating fan blows air into the hollow rotating shaft through the air supply pipe. The airflow flows into the impregnation cylinder through the exhaust groove on the rotating shaft. The airflow in the impregnation cylinder is discharged from the drain hole to dry the impregnated stator core of the winding in the impregnation cylinder.

[0023] Eighth: Start the rotary motor. The rotary motor drives the drive shaft and the drive wheel on the drive shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt. The driven wheel drives the rotary shaft and the stirring rod on the rotary shaft to rotate. The stirring rod stirs the varnish-impregnated winding stator core in the varnish impregnation tank. This can separate the winding stator core from the excess varnish and also allow the varnish-impregnated winding stator core to fully contact the airflow carrying heat, thus fully drying the varnish-impregnated winding stator core.

[0024] Ninth: After the varnished stator core is dried, turn off the rotating motor and heating fan, take out the varnished stator core from the varnishing drum, and put in the varnished stator core that needs to be varnished to continue the varnishing and drying process.

[0025] Tenth: After the stator core of the winding is impregnated and dried, turn off the drive motor, heating fan, and rotary motor, clean the impurities generated during the impregnation and drying process of the stator core of the winding, and disconnect the power supply.

[0026] Beneficial effects:

[0027] 1. The drive motor drives the double-threaded screw to rotate in the forward or reverse direction. The two connecting rings on the double-threaded screw move towards or away from each other. The fixing plate on the connecting ring drives the bottom end of the push rod to move through the pin shaft, so that the top end of the push rod pushes the bearing plate upward or downward. The bearing plate drives the varnish-impregnating cylinder and the cover plate to rise or fall, removing the varnish-impregnating cylinder from the varnish tank or putting the varnish-impregnating cylinder into the varnish, which facilitates the varnish impregnation of the winding stator core in the varnish-impregnating cylinder and improves the varnish impregnation efficiency of the winding stator core.

[0028] 2. The heating fan blows air into the hollow rotating shaft through the air supply pipe and connecting pipe. The airflow flows into the impregnation barrel through the exhaust trough, increasing the pressure in the varnish tank. This allows the winding stator core to be impregnated under high pressure, enhancing the impregnation quality of the stator core. The heating fan blows air into the hollow rotating shaft through the air supply pipe and connecting pipe. The airflow flows into the impregnation barrel through the exhaust trough on the rotating shaft. The airflow in the impregnation barrel is discharged through the drain hole, drying the impregnated winding stator core in the impregnation barrel, improving the drying efficiency and quality of the winding stator core.

[0029] 3. The bottom end of the rotating shaft is inserted into the impregnation tank. A stirring rod is installed on the rotating shaft inside the impregnation tank. A driven wheel is installed on the rotating shaft below the cover plate. The driven wheel is connected to the driving wheel via a belt. The rotating motor drives the transmission shaft and the driving wheel on the transmission shaft to rotate. The driving wheel drives the driven wheel to rotate via a belt. The driven wheel drives the rotating shaft and the stirring rod on the rotating shaft to rotate. The stirring rod agitates the winding stator core inside the impregnation tank, so that the winding stator core is in full contact with the varnish or the airflow carrying heat, and performs a thorough impregnation or drying treatment on the winding stator core, thereby improving the impregnation and drying efficiency and quality of the winding stator core.

[0046] An operating method for an integrated machine for impregnating and drying winding stator cores includes the following steps:

[0047] First: Move the integrated winding stator core impregnation and drying machine to a suitable location and check whether the circuit of the integrated winding stator core impregnation and drying machine is normal, and whether the drive motor 5, heating fan 18, and rotary motor 22 can work normally.

[0048] Second: Start the drive motor 5. The drive motor 5 drives the double screw 7 to rotate in the forward direction. The two connecting rings 6 on the double screw 7 move towards each other. The fixing plate 15 on the connecting ring 6 drives the bottom end of the push rod 10 to move through the pin 9, so that the top end of the push rod 10 pushes the bearing plate 2 upward. The bearing plate 2 drives the paint dipping cylinder 3 and the cover plate 17 to rise, and removes the paint dipping cylinder 3 from the paint tank 1.

[0049] Third: Inject paint into paint tank 1, put the winding stator core that needs to be impregnated into paint cylinder 3, start drive motor 5, drive motor 5 to drive double screw 7 to rotate in the opposite direction, and lower the bearing plate 2, drive impregnation cylinder 3 and cover plate 17. When cover plate 17 covers paint tank 1, turn off drive motor 5.

[0050] Fourth: The paint in the paint tank 1 flows into the paint dipping cylinder 3 through the leakage holes 32 on the side wall and bottom of the paint dipping cylinder 3, and performs paint dipping treatment on the winding stator core in the paint dipping cylinder 3.

[0051] Fifth: Start the rotary motor 22. The rotary motor 22 drives the transmission shaft 24 and the drive wheel 25 on the transmission shaft 24 to rotate. The drive wheel 25 drives the driven wheel 26 to rotate through the belt 29. The driven wheel 26 drives the rotary shaft 23 and the stirring rod 27 on the rotary shaft 23 to rotate. The stirring rod 27 stirs the winding stator core in the varnish impregnation tube 3, so that the winding stator core is in full contact with the varnish liquid, and the winding stator core is fully impregnated.

[0052] Sixth: In order to enhance the varnishing effect of the winding stator core, the heating fan 18 can be started during the varnishing process of the winding stator core. The heating fan 18 blows air into the hollow rotating shaft 23 through the air supply pipe 19. The air flows into the varnishing cylinder 3 through the exhaust trough 28, which increases the pressure in the varnish tank 1, so that the winding stator core can be varnished under high pressure.

[0053] Seventh: After the stator core of the winding is impregnated with varnish, start the drive motor 5. The drive motor 5 drives the double screw 7 to rotate in the forward direction. The support plate 2 drives the impregnation cylinder 3 and the cover plate 17 to rise. The excess varnish in the impregnation cylinder 3 flows out through the drain hole 32. The varnish that falls on the support plate 2 flows back to the varnish tank 1 through the through groove 14. The heating fan 18 blows air into the hollow rotating shaft 23 through the air supply pipe 19. The airflow flows into the impregnation cylinder 3 through the exhaust groove 28 on the rotating shaft 23. The airflow in the impregnation cylinder 3 is discharged from the drain hole 32. The impregnated stator core of the winding in the impregnation cylinder 3 is dried.

[0054] Eighth: Start the rotary motor 22. The rotary motor 22 drives the transmission shaft 24 and the drive wheel 25 on the transmission shaft 24 to rotate. The drive wheel 25 drives the driven wheel 26 to rotate through the belt 29. The driven wheel 26 drives the rotary shaft 23 and the stirring rod 27 on the rotary shaft 23 to rotate. The stirring rod 27 stirs the varnish-impregnated winding stator core in the varnish impregnation tube 3, which can separate the winding stator core from the excess varnish and also allow the varnish-impregnated winding stator core to fully contact the airflow carrying heat, thus fully drying the varnish-impregnated winding stator core.

[0055] Ninth: After the varnished stator core is dried, turn off the rotary motor 22 and the heating fan 18, take out the varnished stator core from the varnishing drum 3, and put in the stator core that needs to be varnished to continue the varnishing and drying process.

[0056] Tenth: After the winding stator core is impregnated and dried, turn off the drive motor 5, heating fan 18, and rotary motor 22, clean the impurities generated during the impregnation and drying process of the winding stator core, and disconnect the power supply.

[0057] Example 2:

[0058] Further improvements were made based on Example 1, as shown in the appendix. Figure 7 As shown, the integrated machine for impregnating and drying the winding stator core has a limiting groove 33 on the varnish tank 1, and a sealing layer 34 and a limiting post 35 at the bottom of the cover plate 17. The limiting post 35 is designed to be inserted into the limiting groove 33. The cover plate 17 moves vertically with the support plate 2 under the action of the drive motor 5, causing the limiting post 35 to rise or fall within the limiting groove 33. This allows the limiting post 35 to limit the cover plate 17 and the support plate 2 during the rising or falling process, thereby improving the stability of the support plate 2 during the adjustment process. The sealing layer 34 increases the sealing between the cover plate 17 and the varnish tank 1, thereby increasing the pressure inside the varnish tank 1. This facilitates the impregnation of the winding stator core under high pressure, thereby enhancing the impregnation efficiency and quality of the winding stator core.

[0059] Working Principle: Check if the circuit of the integrated winding stator core impregnation and drying machine is normal, and whether the drive motor 5, heating fan 18, and rotary motor 22 are working properly. Start the drive motor 5, which drives the double screw 7 to rotate forward. The two connecting screw rings 6 on the double screw 7 move towards each other. The fixing plate 15 on the connecting screw ring 6 drives the bottom end of the push rod 10 to move through the pin 9, so that the top end of the push rod 10 pushes the bearing plate 2 upward. The bearing plate 2 drives the impregnation cylinder 3 and the cover plate 17 to rise, removing the impregnation cylinder 3 from the paint tank 1. Paint is injected into the paint tank 1. The winding stator core that needs to be impregnated is placed into the impregnation cylinder 3. Start the drive motor 5, which drives the double screw 7 to rotate in the reverse direction, moving the bearing plate 2 and the impregnation cylinder 3 and the cover plate 17 upward. 7. When the cover plate 17 covers the paint tank 1, the drive motor 5 is turned off. The paint in the paint tank 1 flows into the impregnation cylinder 3 through the drain holes 32 on the side wall and bottom of the impregnation cylinder 3, impregnating the winding stator core inside the impregnation cylinder 3. The rotary motor 22 is started, which drives the drive shaft 24 and the drive wheel 25 on the drive shaft 24 to rotate. The drive wheel 25 drives the driven wheel 26 to rotate through the belt 29. The driven wheel 26 drives the rotary shaft 23 and the stirring rod 27 on the rotary shaft 23 to rotate. The stirring rod 27 agitates the winding stator core inside the impregnation cylinder 3, ensuring that the winding stator core is in full contact with the paint, thus performing a thorough impregnation treatment on the winding stator core. To enhance the impregnation effect of the winding stator core, an additional step can be taken during the impregnation process. Hot air blower 18 blows air into the hollow rotating shaft 23 through air pipe 19. The airflow flows into the impregnation cylinder 3 through exhaust duct 28, increasing the pressure in the paint tank 1. This allows the winding stator core to be impregnated under high pressure. After the winding stator core is impregnated, drive motor 5 is started. Drive motor 5 drives the double screw 7 to rotate forward. The support plate 2 drives the impregnation cylinder 3 and cover plate 17 to rise. Excess paint in the impregnation cylinder 3 flows out through the drain hole 32. The paint that falls onto the support plate 2 flows back into the paint tank 1 through the through groove 14. Hot air blower 18 blows air into the hollow rotating shaft 23 through air pipe 19. The airflow flows into the impregnation cylinder 3 through exhaust duct 28 on the rotating shaft 23. The airflow in the impregnation cylinder 3 is discharged through the drain hole 32. The varnish-impregnated stator core in the impregnation tank 3 is dried by starting the rotary motor 22, which drives the drive shaft 24 and the drive wheel 25 on the drive shaft 24 to rotate. The drive wheel 25 drives the driven wheel 26 to rotate via the belt 29. The driven wheel 26 drives the rotary shaft 23 and the stirring rod 27 on the rotary shaft 23 to rotate. The stirring rod 27 agitates the varnish-impregnated stator core in the impregnation tank 3, which not only separates the stator core from the excess varnish, but also allows the varnish-impregnated stator core to fully contact the heat-carrying airflow, thus thoroughly drying the varnish-impregnated stator core. After the varnish-impregnated stator core is dried, the rotary motor 22 and the heating fan 18 are turned off, and the varnish-impregnated stator core in the impregnation tank 3 is removed.Place the stator core requiring varnish impregnation into the winding for further impregnation and drying. After the stator core is impregnated and dried, turn off the drive motor 5, heating fan 18, and rotary motor 22. Clean out any impurities generated during the impregnation and drying process, and disconnect the power supply.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. An operating method applicable to the integrated winding stator core impregnation and drying machine as described in any one of claims 1-8, characterized in that: The operation method includes the following steps: First: Move the integrated winding stator core impregnation and drying machine to a suitable location and check whether the circuit of the integrated winding stator core impregnation and drying machine is normal, and whether the drive motor, heating fan and rotary motor can work normally. Second: Start the drive motor. The drive motor drives the double screw to rotate in the forward direction. The two connecting rings on the double screw move towards each other. The fixing plate on the connecting ring drives the bottom of the push rod to move through the pin shaft, so that the top of the push rod pushes the bearing plate upward. The bearing plate drives the paint dipping cylinder and the cover plate to rise, and removes the paint dipping cylinder from the paint tank. Third: Inject paint into the paint tank, put the winding stator core that needs to be impregnated into the impregnation cylinder, start the drive motor, and make the drive motor drive the double screw to rotate in the opposite direction, so that the support plate moves the impregnation cylinder and the cover plate down. When the cover plate covers the paint tank, turn off the drive motor. Fourth: The paint in the paint tank flows into the paint dipping cylinder through the drain holes on the side wall and bottom of the paint dipping cylinder, and the winding stator core inside the paint dipping cylinder is impregnated with paint. Fifth: Start the rotary motor. The rotary motor drives the drive shaft and the drive wheel on the drive shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt. The driven wheel drives the rotary shaft and the stirring rod on the rotary shaft to rotate. The stirring rod stirs the winding stator core in the impregnation barrel, so that the winding stator core is in full contact with the varnish, and the winding stator core is fully impregnated. Sixth: In order to enhance the impregnation effect of the winding stator core, a heating fan can be started during the impregnation process of the winding stator core. The heating fan blows air into the hollow rotating shaft through the air supply pipe. The air flows into the impregnation tank through the exhaust trough, increasing the pressure in the varnish tank, which allows the winding stator core to be impregnated under high pressure. Seventh: After the stator core of the winding is impregnated with varnish, start the drive motor. The drive motor drives the double screw to rotate in the forward direction. The support plate drives the impregnation cylinder and cover plate to rise. The excess varnish in the impregnation cylinder flows out through the drain hole. The varnish that falls onto the support plate flows back to the varnish tank through the through groove. The heating fan blows air into the hollow rotating shaft through the air supply pipe. The airflow flows into the impregnation cylinder through the exhaust groove on the rotating shaft. The airflow in the impregnation cylinder is discharged from the drain hole to dry the impregnated stator core of the winding in the impregnation cylinder. Eighth: Start the rotary motor. The rotary motor drives the drive shaft and the drive wheel on the drive shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt. The driven wheel drives the rotary shaft and the stirring rod on the rotary shaft to rotate. The stirring rod stirs the varnish-impregnated winding stator core in the varnish impregnation tank. This can separate the winding stator core from the excess varnish and also allow the varnish-impregnated winding stator core to fully contact the airflow carrying heat, thus fully drying the varnish-impregnated winding stator core. Ninth: After the varnished stator core is dried, turn off the rotating motor and heating fan, take out the varnished stator core from the varnishing drum, and put in the varnished stator core that needs to be varnished to continue the varnishing and drying process. Tenth: After the stator core of the winding is impregnated and dried, turn off the drive motor, heating fan, and rotary motor, clean the impurities generated during the impregnation and drying process of the stator core of the winding, and disconnect the power supply.
