Magnet Bonding
For electric drives, performance, weight and space savings are key. This increases the demands on the materials in terms of mechanical, chemical and thermal resistance in order to ensure long-lasting operation. Adhesives meet these requirements, adhere to various metals, ferrites and copper coils and are suitable for a wide range of applications, such as bonding stator stacks, thread windings or commutator fuses, right through to potting bar magnets.
Adhesives are the perfect solution for bonding magnets, as modern adhesives not only optimize the joining of housings and magnets, but can also protect and insulate the coil windings.
Adhesives with high adhesion to metals are required for these applications. Since metals are not permeable to UV light, Hoenle offers dual-curing adhesives in addition to thermal cure products. These dual cure adhesives cure primarily by UV light, with a secondary anaerobic or moist curing mechanism for shaded areas.
