Optimization of Induction Motor Equivalent Circuit Parameter Estimation Based on Manufacturer’s Data

Abstract: This paper presents a two-stage optimization of the parameters of a seven-parameter equivalent circuit of three-phase induction motor. The initial parameters of this equivalent circuit are estimated by a method called the Engineering Method using the data given in the manufacturer's data sheet. The two-stage parameter optimization procedure was developed to minimize the errors between the estimated and the actual values in motor torque and current. In the first stage, the method is targeted to optimize the par… Show more

“…Another useful technique is to change the stator winding [18][19][20][21][22], such as Y-∆ hybrid windings [18][19][20], concentric single-double layer windings [21] or adjust the parameters of single layer and double layer windings [22], to increase motors efficiency. Therefore, techniques for changing the type of stator windings and the air gap length are investigated in this paper.Many calculation methods have been developed to predict the running performance of induction motors [2,21,[23][24][25][26][27][28]. The steady-state performance of induction motors, including losses distribution, can be obtained by improving algorithms in FEM [2,23-25], but this method usually need researchers to write their own FEM program, which may be too complex to realize by other researchers and manufacturers.…”

“…The steady-state performance of induction motors, including losses distribution, can be obtained by improving algorithms in FEM [2,23-25], but this method usually need researchers to write their own FEM program, which may be too complex to realize by other researchers and manufacturers. The steady-state and transient-state of induction motors can be carried out through circuit models [2,21,[26][27][28]. Researchers have used FEM to determine the parameters of the equivalent circuit model which considers the impacts of stray losses and harmonic torques [26].…”
