摘要： An electromagnetic submersible pump (P) has an outer cylindrical stator with a laminated inner cylindrical conductive core (K) for pumping sodium in the duct (D) defined therebetween. The duct (D) defines an inlet (26) at the bottom and an outlet (28) at the top. The outer stator generates upwardly conveyed toroidal magnetic fields which convey sodium from the inlet (26) to the outlet (28). The outer stator has a vertically disposed duct surrounded by alternately stacked layers of coil units and laminates. Upper and lower coil halves of spirally wound common copper bus are joined in series at the center. These upper and lower coil halves are connected as discrete coil units (U) on the coil unit exterior for forming complementary magnetic fields between the coil halves. These coil units, are provided with parallel connection of sequential coil units in groups of four units to each phase of a three phase of 15 Hertz 700 volt RMS power supply. A magnetic field conducting laminate construction (L) sandwiches each coil unit (U) within the outer stator. The laminate construction also maintains rigid heat transferring contact with the central duct in the pump stator to conduct resistance heating away from the coils. Additionally this rigid contact of the laminates to the duct prevents pump wear due to pumping reaction and resultant vibration of the coil unit and laminate layers of the stator. The laminate construction includes an endless arch of hoop tensioned laminates maintained in intimate contact with the stator central duct by a surrounding and peripheral hoop tension wire preferably of molybdenum. Due to differential thermal expansion in which the individual laminates are radially compressed to the central duct by the elastic hoop tension forces in the wire, firm contact with the central duct is maintained during pump operation.

摘要： A submersible linear pump (P) for pumping liquid sodium includes a stator having a central cylindrical duct (D) surrounded by coils (C) in slots interleaved with magnetic flux conducting elements (L), forming a continuous magnetic field conduction path along the stator. A cylindrical magnetic conducting core (K) is in the duct. Pump operation occurs by static windings (C) in the outer stator sequentially conveying toroidal fields from the pump inlet (524) to the pump outlet (526). The stator has many poles distributed along its length, each energized by a multi-phase supply (ABC). There are multiple slots per pole per phase. Each phase (e.g. A) has a number of windings in parallel on each pole (A₁, A₂, A₃, A₄) equal to or less than the number of slots per pole per phase. The slot sequence per pole per phase is chosen to equalize the variations in flux density of the sodium as it passes into the inlet (524) with little or no flux and acquires magnetic flux as it moves to the outlet (526). The parallel windings of each phase are placed in symmetrically permuted slots in successive poles to equalize phase angle shifts between the slots of each pole at each phase in each leg. Conventional high voltage series connection of all the poles is avoided. Coil voltages are reduced and insulating materials of lower dielectric rating can be used.
