The assembly and integration of core lamination is a crucial step in the manufacturing of transformers, motors, and other electrical devices. This production process involves stacking individual laminations together to form the core, ensuring proper alignment and insulation, and integrating the core with other components. The assembly and integration of core laminations require careful attention to detail and precision to ensure optimal performance and reliability of electrical devices, and Fabmann offers turnkey lamination bonding & assembly services for stator cores, rotors, armatures, and pole lamination assemblies.

Assembly Intergration

 

Fabmann offers turnkey lamination bonding & assembly services for stator cores, rotors, armatures, and pole lamination assemblies, and our lamination capability covers stator laminations, rotor laminations, armature laminations, lamination end plates, finger plates, vent assemblies, and pressure plate rings. We handle complex lamination designs with low volume applications, and our custom manufacturing and assembly solutions cover all your motor lamination needs. Our operation team is able to handle precision fabrication throughout the process of laser cutting or stamping metal sheets into laminations, coating them and bonding or welding them together to form the core of the motor, and our motor lamination service includes rotor lamination, stator laminations, laser lamination as well as stamping lamination.

 

 

What the production process of assembly and integration?

 

The assembly and integration of core laminations require careful attention to detail and precision to ensure optimal performance and reliability of electrical devices, and therefore strict production process control is vital for sound performance, and the steps are listed below:

 

  1. √ Lamination preparation, and this process includes three steps: cleaning, annealing and insulation. Cleaning means that laminations are cleaned to remove any contaminants that could affect their electrical properties, and laminations are annealed to relieve stress and improve their magnetic properties afterwards. The final step is to coat the laminations with an insulating material to prevent eddy currents and short circuits.
  2. √ Lamination stacking, alignment and clamping, laminations are stacked in a specific order, typically with alternating orientations to minimize eddy current losses, and then they are carefully aligned to ensure proper magnetic flux paths and minimize air gaps. The final step is to clamp the stacked laminations together to maintain their position and shape.
  3. √ Integration & frame assembly, the core is integrated with the windings, ensuring proper alignment and magnetic coupling, and the core is then assembled into the device frame, typically using bolts or welding.

 

Our operators follows the manufacturing procedures strictly, and we can help you to produce high-quality cores that meet the demanding requirements.

Core Lamination Assembly

 

How does Fabmann perform inspection on assembly and integration?

 

One of our biggest advantage is that we have comprehensive in-house capabilities covering full time team, experienced welding engineers, advanced manufacturing facilities, and QA team. Our skilled welding specialist can perform MIG and TIG welding, as well as spot, laser, and CNC robotic welding. We can also bond all your custom core assemblies with high precision. Plus, our team can do reverse engineer and manufacture stator laminations, rotor laminations, armature laminations, lamination end plates, finger plates, vent assemblies, and pressure plate rings, to achieve this result, our QA team perform strict process control covering following aspects:

 

Dimension Check of Core Lamination Assembly

Dimension Check of Core Lamination Assembly

 

  • 1. Lamination surface defects or misalignments.
  • 2. Lamination material thickness, and it has impact on the operating frequency and desired core losses.
  • 3. Lamination shape & dimension
  • 4. Annealing
  • 5. Non-destructive testing (NDT), ultrasonic testing is usually used to inspect the core for defects.

 

We have advanced manufacturing equipment such as fully automatic high-speed progressive punching machines, CNC high-speed single-slot punching machines, stator press-fitting. Meanwhile we are working very closely with rotor aluminum casting specialist, and our production can carry out special processes such as tangential bevel grooves and spiral bevel grooves with diameter up to 1,250mm. Our products are widely used in nuclear power, wind power, ships, mining, petrochemicals, rail transportation, new energy vehicles and other fields, and our engineering team is dedicated to provide high quality custom core lamination with full assembly and integration service.
