  • Method and device for pneumatically driving a turbocharger rotor in a balancing machine
    Patent number: 9581166
    Abstract: Disclosed is a method in which the propulsive power of a drive nozzle (2) is controlled by means of a programmable logic control device (24) having an adjustable internal controller (25) in dependence upon the rotational frequency of a turbocharger rotor (1) detected by a speed sensor (26). Parameters necessary for control are determined empirically in a tuning run which includes tuning the controller (25) to a proportional control action with high gain Kp and inputting the nominal balancing speed as target value for the controller (25), monitoring and comparing the actual speed with the target value. If the actual speed exceeds the set target value, halving the gain Kp of the controller (25) and repeating the run until the actual speed is below the set target value.
