* Magnetic loss of Rotors
* Damage on the magnet portion of Rotors
When handling or storing multiple Rotors, be sure to keep a proper distance
between Rotors as shown in

Finger injury caused by pinching between Rotors pulling each other.
•
Magnetic loss of Rotors or damage on the magnet portion of Rotors. (
