Our Full-face Bonding Lamination Stacks Capabilities
Full-face bonding of the laminations is a type of silicon steel lamination used in electric motors, generators, and transformers. These laminations have a special coating that allows them to adhere to each other without the need for additional adhesive or bonding agents. The process of creating self-bonding motor laminations typically involves several steps:
The lamination bonding process uses a roll coat process that applies an insulating adhesive bonding agent to the motor lamination sheets. This material is typically a type of epoxy or polymer that is applied as a liquid and then cured.
The individual lamination sheets are stamped, wire-cut, or laser-cut to the desired shape and size.
Based on the requirements, a fixture is designed using CAD software or other design tools. The built fixture should be designed to securely hold the laminations in place and apply the required pressure evenly across the surface.
These laminations are then stacked together to form the core of the motor or transformer.
The coated laminations are second cured at a specific temperature and for a specific period to ensure that the bonding material has achieved its high bonding strength and formed a strong bond between the laminations.
Benefits Of Self-Bonding Motor Core Laminations
Self-bonding iron core laminates, also known as join stacked rotor and stator laminations, offer several benefits over traditional laminations that use adhesives or mechanical fasteners:
Enhanced Efficiency
Ensuring the structural integrity of laminate stacks through the use of bonding varnish (also known as backlack) and glue-dot bonding. This reduces core losses and improves the efficiency of the motor.
Cost Savings
While the initial cost of self-bonding laminations may be higher than traditional laminations, the overall cost of the motor can be reduced due to improved efficiency and reliability.
High Precision
Surface contact uniformity has been notably enhanced, while flatness and verticality have seen an improvement exceeding 50% (as measured by a 0.05mm feeler gauge).
