Capacities Of Laser Welding Rotor And Stator Laminations

This bonding process employs focused laser beams to achieve precise and robust fusion between electrical steel laminations.


Our laser welding process focuses a high-intensity laser beam on stamped stator and rotor lamination stacks. It melts the metal material through a laser-generated heat source.


Because it can precisely control the melting process, it can minimize the influence of the hot zone. We confine the hot zone to a small area to reduce the risk of deformation or damage to the motor core.


Our automatic laser welding machine adopts a 4-way fiber transmission, manual feeding, automatic pressing into the fixture, rotating three times, and completing 12 welds.


Our technicians will set different levels of laser energy and wavelength for different materials.

Advantages Of Motor Lamination Bonding

Precision: Precision welding works with pinpoint energy input, making it ideal for intricate and detailed welding tasks.

Minimal Heat Affected Zone (HAZ): The focused laser beam minimizes the heat-affected area, reducing distortion and preserving material properties.

High Strength: Welding produces solid, durable welds with excellent joint integrity and no electrode wear.

No Consumables: This process does not need to add fillers, reducing operational costs.

Versatility: It can be used with various materials, from metals to plastics, accommodating diverse applications

Narrow Weld Seam: Excellent weld seam with an easily definable seam depth and no cavities in the weld seams.

High Welding Speed: The concentrated energy of the laser beam facilitates rapid melting and solidification, resulting in efficient welding processes.

Contactless Welding: It is a non-contact process—the laser beam welds without contact.

Minimal Distortion: The localized heating and cooling of welding lead to minimal distortion in the surrounding material.

Micro-Welding: It can be scaled down for micro-welding applications, suitable for smaller cores.
