Abstract:
    The drive control method of the motor in the pendant centrifugal separator is characterized in that a permanent magnetic synchronous motor is applied to the pendant centrifugal separator, and a motor drive control part 1 performs the leading compensation controlling by combining the feed forward control with the variable PI control and the equivalent disturbance variable compensation control depending on the amount of load inertias until the amount of deviations of the targeted rotation speed becomes a first preset value and performs the fixed PI control when the amount of variations of the targeted rotation speed reaches the first preset value.
