As the core components of the motor, the rotor and stator do have many differences in production requirements, production conditions and specific processes in their assembly lines. The following is a detailed comparison and analysis of these differences by Vacuz, I hope it can help you!

1. Production requirements

Rotor assembly line requirements

1. Machine configuration: The rotor assembly line needs to be equipped with sophisticated equipment, such as racks, precision ball screws, guide rails, cylinders, motors and servo drives, etc. These equipment together ensure the stable performance of the production line operation.

‌2. Flexibility and adaptability: The equipment should have high flexibility and ductility so that it can flexibly add or modify assembly steps to meet the needs of different products.

‌3. Real-time monitoring and feedback: The production line should have real-time monitoring functions to monitor each process in real time to ensure product quality. Once unqualified products are found, they should be fed back in real time and processed.

‌4. Safety performance: Electrical equipment should be equipped with overcurrent protection and protective grounding circuits to ensure the safety of operators. At the same time, the equipment should have good insulation resistance and withstand voltage, and be equipped with an audible and visual alarm system to further ensure production safety.

Requirements for stator assembly production line

‌1. Stator winding machine‌: For brushless motors, the stator winding machine needs to meet the winding requirements of high accuracy and high efficiency. The equipment configuration and winding process have high requirements on the performance of the stator winding machine to ensure the winding quality and efficiency.

2.‌Electrical performance‌: Stator assembly needs to pay special attention to electrical performance, such as insulation resistance, winding resistance, withstand voltage, etc. These performances directly affect the operating stability and safety of the motor.

‌3. Mechanical structure‌: Stator assembly also needs to consider the stability and reliability of the mechanical structure to ensure that the stator will not be deformed or damaged during the operation of the motor, thereby ensuring the overall performance of the motor.

2. Production conditions

Production conditions for rotor assembly production line

‌1. Environmental conditions‌: The production line should operate under specified environmental conditions, including appropriate temperature, humidity and altitude to ensure the normal operation of the equipment and the production quality of the product.

‌2. Power supply requirements‌: The power supply voltage and frequency should meet the equipment requirements to ensure the normal operation and production efficiency of the equipment.

‌3. Production line capacity indicators‌: The production line should meet certain requirements for line speed, production rhythm and various process parameters to ensure that production efficiency and quality meet the expected goals.

Production conditions of stator assembly production line

‌1. Winding equipment‌: It is necessary to equip a professional stator winding machine to meet the needs of high-precision and high-efficiency winding. The performance and configuration of the winding machine directly affect the quality and efficiency of winding.

‌2. Test equipment‌: It is necessary to equip professional test instruments such as megohmmeter, microohmmeter, withstand voltage tester, etc. to perform electrical tests on the winding to ensure that the electrical performance meets the requirements.

3. ‌Production environment‌: It also requires suitable environmental conditions such as temperature, humidity and altitude, as well as power supply voltage and frequency that meet the equipment requirements to ensure the normal operation of the equipment and the production quality of the product.

3. Process Differences

Rotor Assembly Process

‌1. Key processes‌: including rotor core magnetic steel insertion, injection molding, stacking, component heating, core shaft shrink sleeve, rotor cooling, riveting nuts, etc. These processes jointly ensure the assembly quality and performance of the rotor.

‌2. Special processes‌: such as magnetization and flux detection, shaft demagnetization, laser marking, etc. These special processes have an important impact on the performance and quality of the rotor.

Stator Assembly Process

‌Key processes‌: including stator winding, paper insertion, coil forming, pre-insertion, overall insertion, flaring, twisting, cutting, welding, coating and varnishing, copper nose welding, etc. These processes jointly ensure the assembly quality and performance of the stator.
‌Special processes‌: such as coil forming and welding processes have high precision requirements and great difficulty, and professional high-end equipment is required to ensure process quality and efficiency.

In summary, the assembly production lines of rotors and stators have significant differences in production requirements, production conditions and specific processes. These differences require us to select appropriate production line configuration and process parameters according to product characteristics and requirements in actual production to ensure product quality and production efficiency.
