Abstract :
Successful application of a variable-frequency drive to a sugar centrifuge is presented. The drive is based on a current-fed inverter. The power circuit is briefly described, and a block diagram of the vector control is presented. Experience in tuning the speed regulator and modifying the torque pulsations in order to prevent coupling chatter is discussed. A specially shaped enclosure accommodates the end user´s space requirements and provides space for the electronics which control the sequence of operation. A number of these drives have been in operation for more than two years, and operating experience concerning cycle time, power consumption, and reliability is presented.<>
