PURPOSE: An ultra high-temperature heat-resist motor pump is provided to composite-coat a heat-resist coating layer, a weaving coating layer, and inorganic material coating layer on a bare copper wire for winding which is composed of a stator unit, thereby maintaining stability, durability, and insulating properties under a ultra high-temperature environment. CONSTITUTION: An ultra high-temperature heat-resist motor pump comprises a casing (110), an impeller (115), a rotor assembly (140), and a stator unit (130). The stator unit includes a space unit capable of receiving the rotor assembly and becomes closed by a stator can (134) while a wire (200) for winding is wound around a stator core (133). The wire for winding includes a bare copper wire, a first heat-resist coating layer of a polyimide series resin, a weaving coating layer, and a second heat-resist coating layer of a polyimide series resin. The first heat-resist coating layer is heat-cured on an outer layer of the bare copper wire, thereby being primarily coated. The weaving coating layer is coated on the outer layer of the first heat-resist coating layer and formed of heat-resist fibers formed by weaving glass fibers. The second heat-resist coating layer is heat-cured on the outer layer of the weaving coating layer, thereby being secondarily coated.
