摘要
A rotor dynamic balancing method for a magnetic levitation molecular pump, which includes the steps of activating an open loop feed forward control module after activating a motor of the magnetic levitation molecular pump; if the maximum radial vibration amplitude does not exceed ½ of a protective clearance during the acceleration of the rotor under the control of the open loop feed forward control module, indicating that the open loop feed forward control module is able to inhibit the co-frequency vibration of the rotor, so as to allow the rotational speed of the rotor to exceed its rigid critical rotational speed; and performing a rotor dynamic balancing operation at a high speed by an influence coefficient method. This method directly performs the rotor dynamic balancing operation with respect to the rotor at a high-speed, which facilitates the rotor dynamic balancing operation so as to perform the rotor dynamic balancing operation more quickly and efficiently.
