2. Precise dynamic balance. after CNC machining, the max. tolerance is only 100μm, which can ensure nice dynamic balance performance. 

Mortise and tenon connection: Full mortise and tenon connection structure, ensuring the safety of the whole fan

1. Motor and hub chassis: through the tight connection between the inner tapered bushing and outer tapered bushing, even if the motor shaft is broken, the inner and outer bushings form a structural self-locking to prevent falling.

2. Chassis and petiole: The petiole and the chassis are connected by hook-type mortise and tenon joints, and the bolts are not stressed to ensure the whole structure strength;
