    URGENT: Rotor Dynamic balancing

    Dear All,
    We have a 90kW electrical motor. we overhaul the motor by replacing the bearing, dust seals, stator cleaning...
    this was done because of bearing damage.

    The stator and stator shaft seems to be OK without any crack, wear or damage.
    Could you please advise whether a dynamic balancing for the rotor is needed or not?
    when such balancing is neede?

    thank you in advance.
