Design considerations of submersible unprotected solid-rotor induction motor

This paper deals with alternative solution of submersible sealed oil-extended motor - submersible unprotected solid-rotor induction motor of 12/18 kW, 750/1500 V, 3000/6000 rpm, which can operate inside oil well, in corrosive medium-strata liquid (mixture of oil, associated water, mineral admixture and oil gas) with ambient temperature 1500degC and pressure 30 MPa. To estimate the performance of the solid rotor motor two-dimensional (2D) nonlinear complex time-harmonic solver is constructed to model the machine in steady-state. Non liner magnetic material characteristics, the different rotor construction were taken into account.
