Summary:The utility model relates to a low frequency submersible motor for the oil field is the mechanical oil recovery in the pit. A low frequency submersible motor, includes the rotor, and the shape of the cross section of rotor conducting bar is trapezoidal, and the cell type adopts the semi -enclosed slot, and its is trapezoidal, and go to the bottom and the surface of rotor has the opening to communicate with each other. Because half locked groove profile is long -pending bigger than conventional electric motor rotor's cell type area for its magnetic flow that passes through increase, the groove leakage reactance reduces, and corresponding pick -up current, starting torque increase can start under the low frequency state smoothly. Low frequency submersible motor owing to pass through electric motor rotor's magnetic flux increase, compares with conventional submersible motor when normal operating simultaneously, and motor rotation number increases, and efficiency improves.
