Abstract
An electric motor driven that includes a pump body and a motor body having a rotor enclosure coupled to the pump body. The motor body further includes a rotatable impeller arranged on a first side of the rotor enclosure. An electric motor arranged on a second side of the rotor enclosure, opposite the first side, the electric motor having a stator, at least one stator coil, terminals connected to the stator coil and a rotor, the rotor including a shaft that is coupled with the impeller. A cover is disposed over the electric motor, the cover having an open end that is attached to the rotor enclosure in a manner that produces a leak-tight chamber inside the cover, the stator and stator coil being arranged inside the leak-tight chamber, the leak-tight chamber being filled with a non-gaseous filler material, the non-gaseous filler material having a thermal conductivity greater than air.
