Abstract

La présente invention concerne un moteur électrique de fond de puits destiné à une pompe submersible qui possède au moins trois phases et comprend un rotor à aimant permanent et un stator portant des enroulements de phases (A, B, C) dans des encoches (2206) ménagées dans le stator. Chaque enroulement de phase (A, B, C) incorpore une bobine s'étendant à travers une paire respective d'encoches de stator contiguës (2206) de sorte que ces bobines s'étendent les unes le long des autres dans cette encoche, qu'elles soient séparées par un espace à travers lequel un fluide de refroidissement peut-être pompé pour refroidir cette bobine, ou qu'elles soient séparées par une projection thermiquement conductrice (3110) avec laquelle les bobines sont en contact thermique, s'étendant au moins en partie sur le passage à travers l'encoche. Un tel agencements d'enroulements permet de faire en sorte que ce moteur est une longue durée de vie.
