A geothermal fluid pump induction motor for use in a deep well submersible pump comprising: a rotatable shaft; a rotor and a stator one of which comprises an induction coil cooperative with said shaft such that upon passage of electric current through said induction coil, rotating movement is imparted to said shaft; a bearing assembly comprising: a bearing housing affixable to the motor section of the deep well submersible pump and configured to transmit a load generated in said shaft to a structure within said motor; a sliding bearing positioned within said housing, said sliding bearing configured to operate in a substantially continuous lubricant environment and comprising: a multilayer bushing disposed against an inner surface of said housing; and a bearing sleeve concentrically disposed within said multilayer bushing and cooperative therewith such that said sleeve rotates relative thereto in response to rotation of said shaft; and a fluid conveying mechanism positioned within said housing and configured to deliver a lubricant between said multilayer bushing and said bearing sleeve such that a lubricant flow path is defined therebetween as part of said substantially continuous lubricant environment; a motor section enclosure disposed about said shaft, said induction coil and said bearing assembly such that said lubricant placed therein may serve as a heat removal medium for said bearing assembly; characterised in that the geothermal fluid pump induction motor further comprises a geothermal fluid passage formed concentrically around said motor section enclosure such that upon thermal contact between a geothermal fluid in said passage and an outer surface of said motor section enclosure, a transfer of heat from said bearing assembly to said geothermal fluid takes place across said motor section enclosure while maintaining fluid isolation between said lubricant and said geothermal fluid a rotatable shaft; a rotor and a stator one of which comprises an induction coil cooperative with said shaft such that upon passage of electric current through said induction coil, rotating movement is imparted to said shaft;
