Self commissioning: A unique feature of inverter-fed induction motor drives

摘要

For the high-performance sensor-less vector control of an induction motor, the accuracy of the motor parameters has an important impact on the performance of the whole system. In this paper the method for self commissioning of inverter fed induction motor drive is presented. The method is based on three frequency-domain tests, performed at standstill, avoiding then the locked-rotor and no-load tests. The proposed algorithm can be implemented in standard motor drives in order to automatically perform self-commissioning.
