US Patent 12123428 Seam-sealed pothead to motor connection

A pumping system configured to recover wellbore fluids from a wellbore includes an electric motor that has a motor head, a pothead receiving bore within the motor head, a motor insulator block within the motor head, and a stator lead within the motor insulator block. The pumping system further includes a motor lead cable and a pothead connector connected between the motor head and the motor lead cable. The pumping system includes a hermetically fused pothead-to-motor connection at an interface between the pothead connector and the motor head that obviates the need for conventional elastomeric seals at the interface between the pothead connector and the motor head.
