Abstract

PURPOSE:To elevate the cooling effect of a stator and a rotor of the submerged motor by a method wherein plural axis directional penetrating holes are provided in the rotor core, covers to surround the rotating shaft are provided at the end faces of the stator core and funs are made to rotate in it to make a liquid refrigerant to be circulated forcibly. CONSTITUTION:Plural penetrating holes 22 in the axial direction are provided in the rotary core 14 of the submerged motor being filled with the liquid refrigerant 20 inside of outer case consisting of a frame 2 and brackets 1. A cover 23 having a small diametrical hole 24 to be penetrated by the rotating shaft 13 is provided at the end face of the stator core 3, and the funs 25 are equipped on the rotating shaft 13 at the part of the hole 24. Accordingly because the liquid refrigerant 20 is made to circulate forcibly through the penetrating holes 22 of the rotor core 14 and the gap (g) between the stator and the rotor, so that the cooling effect of the stator and the rotor are elevated together and the reliability is also elevated.
