Electric Motor Magnet Bonding: Increasing UPH With Fixation-Aid-Free Process Design

DELO offers dual-curing adhesives for structural bonds that demand high loads. They combine high strength and temperature resistance with a simple production process, making it ideal for use in automotive applications like the production of electric motors where magnets are fixed in the rotor package. These products can be prefixed in one to five seconds, depending on the intensity of the UV light, eliminating the need for a holding device that must be assembled, disassembled and cleaned after curing. They typically reach full strength within 20 minutes of subsequent heat curing at 130 °C. Full strength can also be achieved with extended curing time at 90 °C or within just a few minutes using induction heating.
