SPM30C (Crash-proof) Type
Industry-leading low NRRO (non-repetitive rotational run-out accuracy) with a high-precision slotless motor and new crash-proof feature!
We have developed an air spindle equipped with a "crash proof" anti-crush function and a "slotless motor" to further improve the rotational speed of the conventional SPM30.
The easier-to-use, higher-performance ShinMaywa air spindle will play an active role in improving the performance of hard disk inspection systems, wafer inspection systems, and DVD inspection systems.

Features
- Equipped with slotless motor
- Crash-proof
- High speed (20,000r/min) ~ NRRO 2nm or less at low speed
(according to our metrics) - Reduces unbalance during high-speed rotation and achieves low vibration.
Unbalance amount 0.05gmm or less
