What adhesive is used for bonding servo motor magnets? Elaplus Epoxy Adhesive EP Series High Strength and High Temperature Resistant Solution

In the structure of servo motors, the adhesion between the rotor and the magnet is a key link that affects the performance and lifespan of the motor. With the development of motors towards high power density, high speed, and high temperature resistance, the adhesive used for magnetic steel bonding must remain stable under high temperature, high centrifugal force, and high vibration conditions.This article will introduce the ELAPLUS epoxy adhesive series suitable for bonding servo motor magnets and rotors, covering both single component and two-component solutions, fully meeting different process and performance requirements. The core challenge of bonding servo motor magnetsThe rotor magnet of servo motors is usually fixed by adhesive bonding. Due to its complex working environment, higher requirements have been put forward for adhesives:Strong high temperature resistance: The operating temperature of the motor can reach 150-180 ° C;High shear strength and resistance to centrifugal force: prevent magnet detachment during high-speed rotation;Low shrinkage rate and high Tg: reduce cracking and stress caused by thermal expansion and contraction;Anti aging and anti vibration: ensuring long-term operational reliability;Adaptation to automated dispensing: Suitable fluidity and curing efficiency are required.In response to these needs, Yilian has launched multiple epoxy structural adhesives that can stably achieve high-strength bonding between magnets and metal rotors.Elaplus servo motor magnet bonding special epoxy adhesive series 1.
