Analytical modelling of one cage rotor induction motor for electric submersible pumps

A new hybrid analytical model (HAM) based on conformal mapping (CM) method and magnetic equivalent circuit (MEC) is presented in this paper for electromagnetic modelling of cage rotor induction motors (CRIMs) used electric submersible pumps (ESPs). For every operating point, the iron parts are modelled with a non-linear MEC to calculate virtual currents, which represent influence magneto motive force (MMF) drops MMF sources stator cores. The effects currents air-gap field then considered using CM Hague's solution. This approach calculating also prepare 3-D lookup table (3-D LUT) each element inductance matrix derivative terms position. These LUTs transient analysis CRIM under no-load loading conditions. accuracy proposed HAM validated by comparing results obtained through corresponding from finite experiment set-up.
