Lingyi Auto Parts Co., Ltd. adopts a new brazing process for the armature. 1 High connection reliability and good mechanical strength
·Anti vibration and impact: The formed solder joints can withstand the centrifugal force, vibration, and impact generated by the high-speed rotation of the motor, effectively preventing fracture due to solder joint fatigue under harsh working conditions, and improving the service life and reliability of the motor.

2. Excellent conductivity

·Low resistance connection: The solder material itself has low electrical resistivity and is tightly bonded to the copper substrate, resulting in extremely low contact resistance. This reduces energy loss and heat generation at the solder joints, improving the efficiency and performance of the motor.
·High current carrying capacity: Low resistance and strong bonding enable brazed joints to carry larger starting and working currents, especially suitable for motors with high power density (such as electric tools, car starter motors, etc.).

3. High production efficiency and easy automation

·High speed processing: Medium frequency or high-frequency induction brazing is currently the mainstream method, with extremely fast heating speed (usually completing the welding of an armature within a few seconds), which is very suitable for large-scale assembly line production.
·High consistency: By precisely controlling the heating time, power, and solder amount, the quality of each solder joint can be highly consistent, reducing the instability caused by human operation.
·Fully automated: The entire process (loading, flux application, solder feeding, heating, cooling, and unloading) can be easily integrated into an automated production line, significantly reducing labor costs and increasing production capacity.

4. Small heat affected zone and minimal workpiece deformation

·Localized precise heating: Induction brazing uses electromagnetic induction to concentrate heating only on the welding area (commutator hook), rather than overall heating. This avoids damage to the armature core and winding insulation due to overheating.
·Protecting the insulation of enameled wire: Rapid local heating means that the heat does not have enough time to conduct a large amount to the straight part of the enameled wire, thus protecting the insulation layer of the enameled wire from being burned and ensuring the quality of the winding.

The armature brazing process, especially automated induction brazing, has become the standard and high-quality process choice for high-performance, large-scale motor production due to its high reliability, high efficiency, and high consistency.
