With centrifugal loads, increasing motor operating speed by 2% can increase the power required to drive the system by 8%. It is important that the effect of speed difference should be considered in the energy calculation in order to obtain more accurate calculation. Motors do not operate in full-load situation all the time, so industry always use inverter to save energy with load operation. If the setting of inverter of air compressor does not ideal, there will be torque shortage, that makes air compressor cannot operate as expect. This research simulates and proves that the torque shortage is caused by fail setting with real data. This problem can be solved by changing the inverter setting or changing an inverter which controls by vector.
