Capabilities Of Motor Core Lamination Welding
At Lamnow, once laminations have been stamped and can be handled, they are stacked into custom fixtures that are precisely compressed. We can perform 10 welds simultaneously on large stator stacks, ensuring efficiency and precision. Our advanced lamination stacking processes allow us to process up to 10,000 stacks per day, meeting the high-volume needs of our customers without compromising on quality or performance.
Laser welding of motor laminations is an automated welding process using a laser beam to fuse metals. Unlike traditional welding, a laser provides a concentrated heat source for narrow welds. It’s versatile, suitable for stainless steel, carbon steel, and aluminum, and often used for smaller cores due to its precision.
TIG welding(Tungsten Inert Gas Welding) is a method used for welding motor stator stacks. It involves using a non-consumable tungsten electrode and Ar shielding gas to create an arc between the electrode and the base material. This method yields high-quality welds with minimal slag inclusion, enhancing weld joint integrity during stator stacking.
MIG welding, known as Metal Inert Gas welding, uses an arc generated between a continuously fed welding wire and the workpiece for heat. The process is protected by shielding gas sprayed from the welding torch nozzle. Common gases used include argon, helium, carbon dioxide, and their mixtures. MIG welding is often favored for joining high-voltage stator cores due to its efficiency and effectiveness in producing reliable welds.
MAG welding, or Metal Active Gas welding, involves adding a small quantity of oxidizing gas like oxygen or carbon dioxide to argon. This mixed gas provides better penetration, making it ideal for welding ferrous metals like carbon steel, alloy steel, and stainless steel, commonly used in the accessories of high-voltage motor stators.
Benefits Of Electric Motor Lamination Stacks Welding
Improved Electrical Performance
Welding eliminates the air gap between laminations that can occur with traditional riveting or bonding methods. This results in optimal electrical performance and efficiency of the motor.
Reduced Eddy Current Losses
The welding process can be optimized to minimize the formation of eddy currents, which can lead to energy losses in the motor. This is especially important in high-efficiency motors.
Better Mechanical Strength
Welding creates a strong bond between the laminations, which increases the overall mechanical strength of the core. This is especially important in motors that experience high mechanical stresses during operation.
