Abstract: | The authors describe the development of a centrifuge drive based on a current-fed inverter. The power circuit 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 was designed to accommodate the end user's space requirement and also to provide space for the electronics that 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 |
