Rail Transportation Motor Lamination Stacking

welding motor stators

Rail transportation motor lamination stacking is a meticulous process crucial for crafting efficient and durable electric propulsion systems.
Precision techniques such as interlocking, welding (laser welding, TIG welding, MIG welding), riveting, and cleating are employed to assemble laminations, forming the motor core.

Interlocking ensures a secure fit, enhancing stability. Laser welding offers a high-precision fusion, minimizing heat-affected zones, while TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding provide strong metal bonds.

Riveting involves fastening laminations using mechanical joints, offering reliability. Cleating, and employing specialized fasteners, further reinforces the structure.

Stators, essential components that generate the magnetic fields within the motor, undergo precision injection molding. This method involves injecting molten material, often a thermosetting resin material, into a mold to form the stator’s intricate shape.

The injection molding process ensures consistency, accuracy, and high production efficiency. It allows for intricate designs, tight tolerances, and optimal material distribution, contributing to the stator’s overall performance.

This technique enhances the motor’s durability, insulation properties, and thermal efficiency, making it a critical step in advancing the reliability and efficiency of transportation motors.
