This paper proposes a non-intrusive method for low-voltage induction motor field efficiency estimation based on the modified equivalent circuit which includes the additional stray-load loss and friction and windage loss parameters for improving accuracy. This method focuses on a simple means without the expensive testing. This paper presents the use of on-site measurement data and speed measurement...
In situ machine efficiency estimation techniques are increasing in importance due to pressures to improve performance and for demand-side management. Numerous techniques have been proposed to estimate the efficiency of an induction motor in situ . Only a few are actually practical considering the level of intrusion and the accuracy. Besides, very little has been done to make these methods compatible...
In-situ efficiency estimation techniques are becoming more attractive due to necessity of efficiency assessment as a demand side energy management tool. Numerous techniques have been proposed to estimate the efficiency of an induction motor in-situ. However, only a few are really practical considering the level of intrusion and the accuracy. Besides, very little was done to make these methods compatible...
