Ferrite – Rotor Bonding
DELO-ML adhesives provide excellent resistance to vibration in high-reliability applications.
What do Ferrite – Rotor Bonding Adhesives do?
Ferrite rotor bonding is a critical process in electric motor assembly, particularly in automotive and industrial applications where vibration, temperature extremes, and chemical exposure are common.
DELO-ML anaerobic adhesives provide a high-performance solution for bonding ferrites to zinc-plated rotor bells, offering superior durability and ease of processing. The adhesives are applied between the ferrite and the metal housing after joining. Initial strength is achieved in as little as 20 seconds.
These one-part adhesives need no mixing and have unlimited working lifetimes. Permanent impact resistance is achieved even after aging at 80°C for 1,500 hours and at -40°C for 500 hours. The assembled parts survive a drop test of 1.5 metres.
Key Features of DELO-ML
- One-part anaerobic-curing adhesives
- Cure in the presence of metal and the absence of oxygen
- Excellent thermal & chemical resistance
- Dual-curing option to “freeze” the visible part of the adhesive
- Flexible, impact-resistant and tension-equalising

Why DELO-ML Adhesive for Ferrite Rotor Bonding?
- Anaerobic Curing: Cures in the absence of oxygen and presence of metal, ideal for ferrite-to-metal bonding.
- One-Part Formulation: No mixing required; unlimited working life before assembly.
- Fast Initial Strength: Achieved in as little as 20 seconds, enabling rapid production cycles.
- Dual-Curing Option: Light-curing available to “freeze” the visible adhesive for immediate handling.
- Impact & Vibration Resistance: Assembled parts withstand drop tests from 1.5 metres and prolonged vibration exposure.
- Thermal Stability: Proven performance after ageing at +80°C for 1,500 hours and -40°C for 500 hours.
Application Process
The adhesive is applied between the ferrite and the rotor bell after joining. No fixture is required, and the bond line remains stable during curing. Light-curing can be used to accelerate handling strength in visible areas.
Adhesive Properties
- Compression & Shear Strength: High mechanical integrity under dynamic loads.
- Temperature Range: -60°C to +200°C.
- Chemical Resistance: Withstands oils, coolants, and cleaning agents.
- Tension-Equalising: Reduces stress concentrations compared to mechanical joints.
Use Cases
- Automotive electric motors
- Industrial drive systems
- Consumer appliances with ferrite-based rotors
