<p>The submerged motor comprises an external case (2) having a tubular shape inside which is coaxially inserted an electric motor unit (3). Closure means (10, 20) are suitable to isolate a room for housing the motor unit (3) inside said case (2) from the fluid present outside the same case (2). Said closure means (10, 20) comprise an upper occlusion member (20) suitable to peripherally engage the internal surface of said case (2) and axially provided with a tubular body (21) carrying, in its internal side, a thrust bearing rolling means (22) suitable to be blocked on an upper portion of said motor shaft (4) to absorb the axial thrusts on the same motor shaft (4).</p> |
