Goal: smaller with higher efficiency.

The stator laminations are bonded together to get lower iron loss and improve motor efficiency with better performance. The stator silicon steel sheet can be punched by stamping mold or EDM wire cutting.

Due to the stator bonding lamination technology has been applied, it do not need to design the inter-lock or welding to laminate the sheet together, so its core loss will be lower.

Loose Lamination (Motor Stator Bonding)

Motor Stator Bonding Lamination Without any Interlock Point or Welding.

As we know, electrical motor designer desire to get higher efficiency for the motors, so seeking a lowest stator iron loss stator core laminations method is crucial for motor efficiency improvement. This motor stator bonding lamination technologies are used to reduce interlaminar loss and corrosion. For our customers who are looking for cores with Ultra-low Core loss, , we offer "loose lamination(stator bonding)" for our stator core laminations as an alternative to welding.

Motor Stator bonding lamination technology by high temperature Epoxy can ensure the stator core laminations do not have self-rivet (interlock) point and welding to get excellent stator stack performance. With Upgrading of Stator Bonding lamination, our technology has been used for mass production many years with stable quality and low failure rate.

If you have any questions about motor stator bonding lamination technoligies and services, please send us drawing for quotation.

Electrostatic Epoxy Insulation Coating

Normally a standard electrostatic coating machine can not 100% coat the stator core laminations slots area especially for small corners, the penetration force are not enough to ensure the coating thickness reach designed spec., this will be harmful for final motor insulaton performance. We optimized electrostatic coating machine and process to ensure the coating quality:

1. Imported ejector from Germany to ensure the motor insulation powder as stronger as electricity and penetration.
2. Efficiency improved 150%-200%
3. Coating evenness lower from 0.05mmto 0.03mm
4. Penetration deepth increase from 12mm to 17mm
5. Solved pain of EPS motor stator coil winding scrap rate from 30% to 0.1%
