Advantages of CFRP Armor Sleeves
9
¬ Very strong
• Allows for much higher stresses compared to metals
• allows for thin walls of the sleeve
¬ Reduce gap between rotor and stator
• Coefficient of thermal expansion is almost near to zero
• low electromagnetic losses
• noise reduction
¬ Low- / non-conductive
• reduce eddy current losses
¬ Light weight
• reduce moment of inertia
• faster motor acceleration

Consideration of the whole system
27.02.2020 10
A sucessful application needs a technical view on the complete system !
Recommended steps are
¬ Planning of assembly method
¬ FE-Analysis for sleeves
¬ Production of prototypes
¬ Assembly trials and validation
¬ If necessary further testings like chemical resistances etc.

¬ Glueing with adhesive
¬ Shrink fit: rotor cooled, CFRP sleeve slides over magnets
¬ Press fit: rotor is slightly oversized, CFRP sleeve pressed over magnets
