Rotors – Magnet Fixing / Overmolding
Decades of experience in challenging automotive and non-automotive environments. Thermoplastic magnet fixing enables proven, reliable, cost effective manufacturing.
- Significantly lower cost than other methods
- Excellent rare earth magnet cost position
- No cure time. No curing. Zero.
- Eliminates messiness of glue
- Uniform mass distribution / better balance
- Can use thermally conductive / electrically insulative materials
- Fixing of either unmagnetized or magnetized magnets
- Free standing rotors and stackable hubs or rings
- Use of "loose laminations" for improved cost
- Integration of shaft / Can achieve double insulation
