How do conductor materials "escort" the long-term stability of custom 3-phase squirrel cage motor?

1. Conductor materials: guarantee of efficient operation and long-lasting durability
As the core component of motor windings, conductor materials have a direct and far-reaching impact on the performance and stability of motors. Custom 3-phase squirrel cage motor always follow the principles of high standards and strict requirements in the selection of conductor materials, and carefully select suitable conductor materials according to different application scenarios and performance requirements.
In most conventional industrial applications, high-purity copper is the preferred conductor material. Copper has excellent conductivity, and its extremely low resistance enables current to be transmitted with minimal energy loss when passing through the winding. This means that during the operation of the motor, the heat generated by the current is effectively reduced and the copper loss is significantly reduced. Efficient operation not only means energy saving, but more importantly, it can effectively avoid a series of problems caused by overheating.
During the long-term operation of the motor, winding overheating is one of the main reasons for its performance degradation and shortened life. Excessive temperature will accelerate the aging of the winding insulation material, gradually reduce its insulation performance, and eventually may cause a short circuit fault between the windings, causing damage to the motor. High-purity copper conductor materials can effectively reduce the heat generated by the winding, so that the motor always remains in a relatively low temperature range during operation, thereby greatly delaying the aging rate of the winding insulation material.
However, in some special application fields with strict weight restrictions, such as aerospace, electric vehicles, and portable devices, aluminum alloy conductor materials have emerged with their unique advantages. Aluminum alloy has the characteristics of high strength, low density and good conductivity. Compared with copper, the density of aluminum alloy is about one-third of that of copper, which greatly reduces the weight of motors using aluminum alloy conductors at the same volume. Custom 3-phase squirrel cage motor using aluminum alloy conductor materials can significantly reduce the overall weight of the aircraft while ensuring good conductivity, and improve its fuel efficiency and flight performance.
At the same time, the high strength characteristics of aluminum alloy conductor materials enable it to withstand various mechanical stresses generated during the operation of the motor, ensuring the structural integrity of the winding during long-term operation. Moreover, a dense oxide film will form on the surface of the aluminum alloy conductor, which has good corrosion resistance and can effectively prevent the conductor from corroding in harsh environments, further improving the reliability and service life of the motor. In application scenarios such as electric vehicles, motors need to operate under frequent starting, braking, and different road and environmental conditions. These characteristics of aluminum alloy conductor materials enable them to adapt well to such complex working conditions and provide reliable power support for the stable operation of electric vehicles.

2. Insulation materials: a solid line of defense for stable electrical performance
Insulation materials play a vital role in customizing three-phase squirrel cage motors. They are like a solid line of defense, ensuring that the electrical system inside the motor can operate in a stable and safe environment. The selection of high-quality insulation materials is one of the key factors to ensure the long-term stable operation of the motor.
The insulation materials used in customizing three-phase squirrel cage motors have excellent electrical insulation performance, high temperature resistance and mechanical strength. Taking the common mica insulation material as an example, mica has extremely high insulation resistance, which can effectively prevent the leakage of current between windings and between windings and iron cores, ensuring the stable and reliable electrical performance of the motor. The advantages of mica insulation materials are particularly obvious in high temperature environments. It has good heat resistance and maintains stable insulation performance for a long time. This allows the motor to operate normally in some high-temperature working environments, such as next to the furnace in the metallurgical industry and near the high-temperature reactor in the chemical industry, without leakage, short circuit and other faults due to the decline in insulation performance.
In addition, with the continuous development of industrial technology and the increasing diversification of application scenarios, the performance requirements for insulating materials are getting higher and higher. Some advanced insulating materials not only have excellent electrical insulation and high temperature resistance, but also have moisture-proof, mildew-proof, and corrosion-resistant properties. In humid environments, such as shipbuilding and aquaculture industries, ordinary insulating materials are easy to absorb moisture, resulting in a decline in their insulation performance. The use of insulating materials with moisture-proof properties can effectively prevent the intrusion of moisture, maintain a dry environment inside the motor, and ensure that the insulation performance is not affected. In some industrial environments with corrosive gases or liquids, such as chemical and electroplating industries, insulating materials with anti-corrosion properties can resist the erosion of chemical substances and prevent the insulating materials from being corroded and damaged, thereby ensuring that the motor can operate stably and for a long time under complex and harsh working conditions.
The mechanical strength of insulating materials should not be ignored either. During operation, the motor will be subject to various mechanical stresses, such as vibration and impact. If the mechanical strength of the insulating material is insufficient, it may crack or deform under the action of these mechanical stresses, thereby destroying its insulation performance. The insulating materials selected for the customized three-phase squirrel cage motor have undergone rigorous quality inspection and performance testing, and have sufficient mechanical strength to withstand various mechanical stresses during the operation of the motor, ensuring the integrity and stability of the insulation structure. For example, in some high-speed motors, the insulating materials need to withstand large centrifugal forces and vibrations. High-quality insulating materials can still maintain good performance in this case, providing reliable protection for the long-term stable operation of the motor.

3. Mechanical structural parts: the cornerstone of stable support and reliable protection
As the supporting skeleton of the customized three-phase squirrel cage motor, the quality of the mechanical structural parts is directly related to the overall stability and reliability of the motor. The customized three-phase squirrel cage motor uses high-strength and corrosion-resistant steel as the raw material of the mechanical structural parts. These steels have undergone rigorous quality inspection and have good mechanical properties, laying a solid foundation for the long-term stable operation of the motor.
During the operation of the motor, various mechanical stresses and vibrations will be generated. For example, when the rotor of the motor rotates at high speed, it will generate a large centrifugal force, and the stator winding will be affected by electromagnetic force when powered on, and these forces will be transmitted to the mechanical structure. If the strength of the mechanical structure is insufficient, it may deform or crack under the action of these forces, thus affecting the normal operation of the motor. The high-strength steel selected for the customized three-phase squirrel cage motor can withstand these mechanical stresses and ensure the structural stability of the motor during long-term operation. For example, in some large industrial equipment, the motor needs to run continuously for a long time and bear a large load. The mechanical structure made of high-strength steel can ensure that the motor can still operate stably in this case and will not fail due to mechanical structure problems.
In addition, the mechanical structure also needs to have good corrosion resistance. In industrial production, the motor may face various harsh environmental conditions, such as humid air, corrosive gases or liquids. If the mechanical structure is not corrosion-resistant, it will gradually be corroded and damaged under the action of these environmental factors, thus affecting the service life of the motor. Mechanical structures made of corrosion-resistant steel can effectively resist the erosion of these corrosion factors and extend the service life of the motor. For example, in the chemical industry, many production processes produce corrosive gases and liquids. Motor housings and other mechanical structures made of corrosion-resistant steel can provide reliable protection for internal electrical components and prevent them from being damaged by corrosion.
