Solution to Prevent Vibration Loosening of Motor Coils: ELAPLUS EP 1767 One-Part Epoxy Structural Adhesive

During long-term motor operation, most equipment failures stem not from severe malfunctions, but from an easily overlooked issue: loosening of coils, lead wires, magnetic sheets and inductive components under sustained vibration. This problem is especially prominent in automotive electronics, motor drives, pressure sensors, wiring harness fixation, inductor securing and motor magnet bonding. Such products constantly endure drastic temperature swings, mechanical vibration, impact loads and harsh electrical operating environments. Inadequate fixation of coil leads or magnetic components will trigger a full range of reliability risks: ■ Fluttering of coil lead wires ■ Fatigue cracking of solder joints ■ Loosened wiring harnesses ■ Displacement or detachment of magnetic sheets ■ Abnormal noise from inductors ■ Fluctuations in electrical performance ■ Increased operating noise of motors ■ Structural failure after prolonged vibration Accordingly, fixing motor coil leads cannot rely solely on plastic latches or ordinary adhesives. A structural adhesive with strong bonding strength, high glass transition temperature (Tg), wide temperature resistance, superior electrical insulation, moisture resistance and robust mechanical properties is essential. For such applications, ELAPLUS recommends the EP 1767 One-Part Epoxy Structural Adhesive. Product Introduction of EP 1767 EP 1767 is a black, solvent-free one-part epoxy structural adhesive. Upon full thermal curing, it delivers outstanding bonding performance, electrical insulation, moisture resistance and mechanical strength, with high adhesion to multiple substrates including metals, glass and ceramics. Wide Range of Applications: ■ Automotive electronics ■ Pressure sensors ■ Wiring harness fixation ■ Motor magnet bonding ■ Inductor securing ■ Motor coil lead wire fixation ■ Structural bonding of electronic components ■ Structural fixation under high-temperature environments EP 1767 is a highly recommended one-part epoxy structural adhesive for applications requiring anti-loosening protection against motor coil vibration, enhanced lead wire fixation reliability and strengthened magnetic sheet bonding. Why Do Motor Coil Leads Tend to Loosen? Coils and lead wires are subjected to multiple types of stress throughout motor operation: ■ High-frequency vibration Motors…
