The thickness of motor core lamination steel grades includes 0.05/0.10/0.15/0.20/0.25/0.35/0.5MM and so on. From large steel mills in Japan and China. There are ordinary silicon steel and 0.065 high silicon silicon steel. There are low iron loss and high magnetic permeability silicon steel. The stock grades are rich and everything is available..

In addition to stamping and laser cutting, wire etching, roll forming, powder metallurgy and other processes can also be used. The secondary processes of motor laminations include glue lamination, electrophoresis, insulation coating, winding, annealing, etc.

You can send us your information, such as design drawings, material grades, etc., by email. We can make orders for our motor cores no matter how big or small, even if it is 1 piece.

Our motor laminate lead times vary based on a number of factors, including order size and complexity. Typically, our laminate prototype lead times are 7-20 days. Volume production times for rotor and stator core stacks are 6 to 8 weeks or longer.

Yes, we offer OEM and ODM services. We have extensive experience in understanding motor core development.

The concept of rotor stator bonding means using a roll coat process that applies an insulating adhesive bonding agent to the motor lamination sheets after punching or laser cutting. The laminations are then put into a stacking fixture under pressure and heated a second time to complete the cure cycle. Bonding eliminates the need for a rivet joints or welding of the magnetic cores, which in turn reduces interlaminar loss. The bonded cores show optimal thermal conductivity, no hum noise, and do not breathe at temperature changes.

Absolutely. The glue bonding technology we use is designed to withstand high temperatures. The adhesives we use are heat resistant and maintain bond integrity even in extreme temperature conditions, which makes them ideal for high-performance motor applications.

Glue dot bonding involves applying small dots of glue to the laminates, which are then bonded together under pressure and heat. This method provides a precise and uniform bond, ensuring optimal motor performance.

Self-bonding refers to the integration of the bonding material into the laminate itself, allowing the bonding to occur naturally during the manufacturing process without the need for additional adhesives. This allows for a seamless and long-lasting bond.

Yes, bonded laminations can be used for segmented stators, with precise bonding between the segments to create a unified stator assembly. We have mature experience in this area. Welcome to contact our customer servic.
