定义
A thermosetting or anaerobic adhesive specifically formulated for bonding stacked electrical steel laminations in electric motor stators. It creates a rigid, vibration-damping bond between laminations while maintaining electrical insulation properties, preventing eddy current losses and reducing acoustic noise during motor operation.
工作原理
The adhesive is applied between laminations before stacking, then cured under pressure and/or heat. During curing, it polymerizes to form a solid, insulating layer that mechanically bonds laminations together while maintaining electrical separation. This prevents relative movement between laminations that causes vibration and noise.
材料
Typically epoxy resins (single or two-component)anaerobic acrylicsor modified phenolic compounds with dielectric fillers like silica or alumina. Formulations include thermal conductivity enhancers and corrosion inhibitors.
Cure Time
30-120 minutes at 80-150°C
Viscosity
500-5000 cP
Shelf Life
6-12 months
Shear Strength
10-25 MPa
Dielectric Strength
>15 kV/mm
Thermal Conductivity
0.5-2.0 W/m·K
Operating Temperature
-40°C to 180°C
标准
ISO 4587ISO 6721DIN EN 60455ASTM D1002

常见问题

Why use adhesive instead of welding or mechanical fastening for stator laminations?

Adhesive bonding provides electrical insulation between laminations to prevent eddy currents, reduces vibration and acoustic noise more effectively than mechanical methods, and distributes stress evenly without creating stress concentrations.

What are the main failure modes of stator bonding adhesives?

Thermal degradation at high operating temperatures, chemical degradation from lubricants or coolants, insufficient curing leading to bond failure, and thermal cycling fatigue causing delamination.

How is adhesive application quality controlled in manufacturing?

Through viscosity monitoring, precise dispensing systems, cure monitoring via temperature profiles, and post-cure testing including shear strength tests and dielectric strength verification.
