Magnetic fusion Ceramic and ferrite magnetic elements are combined to form adhesive glue. This mixture yields a strong glue that can be utilised in a variety of industrial and commercial applications. Magnetic bonding adhesive glue, for example, is highly beneficial in the manufacture of electric motors.
Adhesive Bonding is the process of bringing two surfaces together, usually with the production of a smooth connection. This may include the use of glue, epoxy, or one of a variety of plastic agents that join via evaporation of a solvent or curing via heat, time, or pressure.
The Global Magnet Bonding Adhesive market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
3M has developed a new magnet bonding glue system for electric motors. The competition to create more efficient electric motors has begun. Improving the mechanism of glueing permanent magnets to rotors and stators is one way to boost efficiency.
3M has unveiled a new magnet bonding adhesive technology that is intended to virtually replace messy liquid adhesives, simplify magnet setup, and provide high bond strength with control over bond line thickness.
The 3M Magnet Bonding glue AU-205 system combines a modified structural epoxy glue with a thickness control system in a low-tack double-sided tape product.
It claims to provide strong binding strength and chemical resistance in an easy-to-convert tape form that is RoHS and REACH compliant and has no volatile organic components.
3M’s new wonder glue is intended to reduce the type of magnet misalignment that may occur with liquid adhesives, which can move uncontrollably if inconsistent pressure is applied during the application and curing processes.
Magnets can be accurately positioned or moved because the adhesive can be “metered” through slitting and cutting or die cutting to eliminate that bothersome adhesive “squeeze-out.”
According to 3m, AU-205 also enhances management of the permanent magnet bond line thickness, which is important for motor performance.
The air gap is the space between the internal diameter of the stator and the outside diameter of the rotor. A PM motor can be more efficient if the rotor/stator air gap is precisely controlled and minimised.
