For 220kg floor-standing heavy equipment, will it be dangerous if the rotor is not placed properly during the experiment?

Won't. The equipment has automatic rotor identification and unbalance automatic detection functions. Once improper installation of the rotor or imbalance of the sample is detected, the system will automatically limit the speed or shut down with an alarm. In addition, this model uses a special inner cavity protective cover and a high-reliability electromagnetic lock to provide double locking security from both physical and logical aspects.
