Lamination Bonding And Stacking Capabilities
Lamnow provides advanced lamination core assembly services, employing techniques like interlocking, welding, self-bonding, gluing, cleating, riveting, and precise shaft insertion. Our capabilities ensure stator and rotor laminations seamless integration, enhancing the efficiency and performance of motor systems.
Interlocking
The interlocking motor lamination, achieved through progressive stamping die on a high-speed machine, is a cost-effective assembly method for stator rotors in mass production.
Welding
The stator lamination welding process involves fusing laminated steel sheets to create the core of an electric motor. Our welding technique includes laser welding, TIG welding, and MIG welding.
Self-Bonding
Self-adhesive involves using bonding varnish laminated steel that bonds to each other during heat treatment. This bonding technique reduces the additional adhesive bonding process.
Gluing
The gluing process involves bonding laminated steel sheets using specialized glues. It is ideal for thin metal sheet laminate products such as HEV drives and other high-efficiency motor cores.
Riveting
The riveting rotor and stator lamination stacks involves securing stacked lamination with rivets. Commonly the rivet size is Φ3mm, but we can use the rivet size according to your request.
Cleating
The stator lamination cleating process involves fastening silicon steel laminates with cleats or clips. We offer two buckle stacking ways, such as straight or skew buckles.
Shaft-Insertion
The shaft inserting process involves precisely fitting the rotor shaft into the motor assembly. It is suitable for small to medium size electric motor range.
Blot
The bolting motor laminations involve securing laminated steel sheets using bolts. It is generally used for stator laminations with larger outer diameters.
Process For Electrical Steel Lamination Stacking
Motor core lamination stacking refers to the process of arranging and stacking thin metal sheets (lamination) to form the core of an electric motor. This process is crucial for optimizing magnetic properties and reducing energy losses.
We use laser cutting, wire-edm cutting, or stamping machines to cut the silicon steel sheets into individual laminations. The dimensions and shape of these laminations are critical for the final motor design.
Our technician cleaned the laminations to remove any contaminations or oils that could interfere with the stacking process and created the stack fixtures.
We use automated stacking machines or manual assembly, depending on the production scale and requirements. Our process employs precision gauge pins accurate to .0001″ for meticulous alignment. After achieving the desired stack height, laminations can be bonded or welded as needed.
If needed, we use hydraulic presses or clamps to compress the stacked laminations. They help to ensure a tight and uniform core structure.
Benefits Of Stator And Rotor Laminations Assembly
Stator and rotor lamination assembly offers myriad benefits. Precision assembly enhances motor efficiency, reducing energy consumption and ensuring optimal magnetic performance. Well-aligned laminations increase durability, minimize noise, and allow for cost-effective, consistent production. Here are some key advantages of motor lamination:
Cost Savings
Interlocking and welding efficient assembly can result in decreased equipment and labor costs during mass production.
Improved Efficiency
Precise assembly stator rotor stacks minimize energy losses, enhancing the overall efficiency and durability of the motor.
Noise Reduction
Properly aligned laminations reduce vibrations and thermal conductivity, leading to quieter motor operation.
