Abstract
An electric motor assembly for pumping a fluid through a fluid cavity includes a stator assembly including a plurality of conduction coils configured to transmit heat energy to the fluid within the fluid cavity. The electric motor assembly also includes a rotor assembly positioned adjacent the stator assembly to define an axial gap therebetween. The electric motor assembly also includes an impeller directly coupled to the rotor assembly opposite the stator assembly such that the rotor assembly and the impeller are configured to rotate about an axis. The rotor assembly and the impeller are configured to be submerged in the fluid within the fluid cavity.
