PURPOSE: To provide the small-sized endoembedment type motor pump, such as auxiliary artificial heart, which is constituted to prevent heating of the endoembedment type motor pump and to prevent the deterioration in the characteristics thereof in spite of high-speed rotation of the pump, is safe to the human body and has a long life.
CONSTITUTION: A motor 5-1 for pump driving of the motor pump 3-1 suitable for embedment into the body of the auxiliary artificial heart, etc., is formed of a material having a good thermal conductivity material and the part formed of the material having the good thermal conductivity is provided with an electron cooler 72. This electron cooler 72 is provided with a heat radiating means 74 for moving the warmed heat generated on the opposite surface of the electronic cooler 72 when the outside of the part formed of the material having the good thermal conductivity in contact therewith is cooled.
