As an important equipment in modern industry, the quality and performance of the brushless motor for water pumps are directly related to the operating efficiency and stability of the entire equipment. Therefore, in the planning and assembly process of the stator and rotor production line of the brushless motor for water pumps, multiple factors need to be considered comprehensively to ensure the smooth operation of the production line and the high quality of the products.

1. Production line planning

1. Determine production needs

Clearly define the production capacity target of the production line, which needs to be considered comprehensively based on factors such as market demand, enterprise scale and production capacity. At the same time, it is also necessary to determine the model and specifications of the brushless motor for water pumps to be produced to ensure the pertinence and applicability of the production line.

2. Equipment selection and layout

According to production needs, select suitable stator winding machines, rotor magnetic tile assembly machines, stator comprehensive testing equipment, varnishing equipment, external grinding equipment, etc. The selection of these equipment is not only related to production efficiency and quality, but also directly affects the overall layout of the production line and the material handling process. Therefore, when selecting equipment, it is necessary to fully consider factors such as equipment performance, precision, reliability and maintainability. At the same time, rationally plan the equipment layout to ensure a smooth production process, reduce material handling and waiting time, and improve production efficiency.

3. Staffing and training

According to the scale of the production line and the number of equipment, corresponding operators and technicians are deployed. These personnel not only need to have relevant professional knowledge and operating skills, but also need to be familiar with and master the equipment on the production line. Therefore, before the production line is put into operation, operators need to be trained in equipment operation, quality control, etc. to ensure that they can complete production tasks independently and accurately.

4. Quality control and testing

Set up multiple quality inspection points on the production line, such as quality inspection after stator winding, quality inspection after rotor magnetic tile assembly, etc. These quality inspection points can timely discover and correct quality problems in the production process to ensure that product quality meets standard requirements. At the same time, equipped with advanced testing equipment, such as stator comprehensive tester, magnetic flux tester, etc., to accurately and reliably test product quality.

5. Material management

Establish a complete material management system to ensure the timely supply and inventory control of raw materials required for production. Optimize the material handling process, reduce material loss and waste, and reduce production costs. At the same time, strengthen the quality inspection and management of raw materials to ensure that the quality of raw materials meets production requirements.

2. Assembly requirements

1. Stator assembly requirements

During the stator assembly process, it is necessary to ensure that the number of winding turns, wire diameter, layout, etc. meet the design requirements. The winding should be tight, uniform, and without broken wires to ensure the electrical performance and mechanical strength of the stator. At the same time, before varnishing, ensure that the stator surface is clean and oil-free. After varnishing, the stator should be dry and well cured without defects such as bubbles and cracks. When grinding the outer circle, ensure that the outer circle of the stator is smooth and flat, and meets the size requirements to ensure the assembly accuracy and operation stability of the stator.

2. Rotor assembly requirements

During the rotor assembly process, it is necessary to ensure that the magnetic tile is accurately and stably assembled on the rotor according to the design requirements without loosening or falling off. The assembly accuracy and stability of the magnetic tile directly affect the magnetic performance and operating efficiency of the motor. Therefore, the assembly quality and accuracy of the magnetic tile need to be strictly controlled during the assembly process. At the same time, the magnetic flux of the assembled rotor is detected to ensure that the magnetic performance meets the standard requirements. In addition, the rotor needs to be dynamically balanced to ensure that there is no obvious vibration and noise when the rotor rotates, so as to improve the running stability and life of the motor.

3. Requirements for stator and rotor assembly

During the stator and rotor assembly process, it is necessary to ensure that the relative position of the shaft extension and the terminal box meets the requirements of the drawings to avoid damage to the windings and bearings. At the same time, adjust the air gap between the stator and the rotor to ensure that the air gap uniformity meets the design requirements. The size and uniformity of the air gap directly affect the electromagnetic performance and operating efficiency of the motor. Therefore, when adjusting the air gap, its size and uniformity need to be strictly controlled. In addition, other components such as external fans and brush devices need to be correctly installed according to design requirements to ensure that the motor operates normally.

4. Quality control and inspection

Many quality inspections are carried out during the assembly process, such as winding quality inspection, magnetic tile assembly quality inspection, dynamic balancing inspection, etc. These quality inspections can promptly discover and correct quality problems in the assembly process to ensure that the assembly quality and product performance meet the design requirements. After the assembly is completed, the whole machine is tested, including no-load operation test, load operation test, etc., to comprehensively evaluate the performance and stability of the motor.

In summary, the planning and assembly requirements of the stator and rotor production line of the brushless motor for water pumps need to comprehensively consider multiple factors, including production needs, equipment selection and layout, staffing and training, quality control and testing, and material management. At the same time, during the assembly process, it is necessary to strictly abide by various assembly requirements to ensure that the product quality meets the standard requirements. Only in this way can high-quality and high-performance brushless motors for water pumps be produced to meet market demand and the needs of enterprise development.
