The invention relates to the field of electrical engineering, namely to asynchronous motors.The sealed squirrel-cage rotor of the liquid-filled asynchronous motor contains a magnetic circuit (1), a shaft (8) and a surface current-conducting layer (7). The magnetic circuit (1) is made of solid sheet ferromagnetic tape with electroinsulating coating and is manufactured by folding the tape in parallel plates, arranged symmetrically to the longitudinal and transversal axes of the rotor with the width limited by the outer circumference of the magnetic circuit (1). The magnetic circuit (1) is electrically connected to and sealed with the surface current-conducting layer (7).

Sealed squirrel-cage rotor of the liquid-filled asynchronous motor

The invention relates to the machine building, particularly to the submersible electric motorsThe submersible electric motor comprises a body (1), a stator (2), a rotor (4), end shields (5, 6) and packing rings (11), filling elements placed into the ring-shaped canals, made on the cylindrical surfaces of the body (1) oriented one to another and the end shields (5, 6)The outer cylindrical surfaces of the end shields (5, 6) form together with the body (1) a single cylindrical surface, the filling elements are made with elastic segments and in the end shields (5, 6) there are made radial openings (7), by that the filling elements are placed into the radial openings (7) flush with the outer surface of the electric motorThe cantilever parts of the body (1) bulge out over the frontal surface of the stator (2) with not more than 30 mmThe technical result consists in providing the mechanization of the winding-insulating works, in decreasing the frame and increasing the reliability of the electric motor
