Adhesive Compounds for Electric Motors and GeneratorsOne and two component epoxy adhesives, sealants and potting compounds offer toughness, high strength adhesion and cost effective performance in electrical motor and generator assembly applications. These compounds are designed to provide thermal stability, resistance to chemicals, vibration, impact and thermal cycling. Additionally, specific formulations provide superior electrical insulation properties, thermal conductivity and gap filling abilities.

Key Benefits of Master Bond Epoxy System

Adhesive bonding has replaced mechanical fastening in electrical motor and generator manufacturing and feature the following advantages:

  • Weight reduction
  • Stresses evenly distributed
  • Improved fatigue resistance
  • High bond strength to similar and dissimilar substrates
  • Prevent corrosion
  • Lower costs
  • Easily automated

A wide range of systems are available with different cure speeds at ambient and elevated temperatures.

Common Uses

Typical uses include assembly and maintenance, such as:

  • Bonding stack laminations
  • Encapsulate stators
  • Reinforcing wires
  • Ring magnets to rotor bonding
  • Lead wire tacking
  • Armature balancing
