    摘要: A structureborne vibration-compensated motor arrangement includes a pair of twin AC motors supported by a rotatable shaft structure and a stationary outer housing. Each motor includes an annular stator core structure and an annular rotor field structure. The stator core structure is mounted by an annular stator support member which, in turn, is stationarily supported by the outer housing. The rotor field structure is mounted by an annular rotor support member in spaced relation, either axially or radially, from stator core structure. The rotor support member, in turn, is mounted to the rotatable shaft structure for rotation therewith. The twin AC motors are mounted with the stator core structures located adjacent opposite sides of the stator support member and the rotor field structures located adjacent the respective stator core structures opposite from the stator support member such that the twin AC motors are arranged back-to-back as mirror images of one another for cancelling out axial and radial vibrations of the stator core and rotor field structures at respectively the outer housing an shaft structure. Additionally, the respective stator and rotor support members are mounted by yieldably resilient members which isolate torsional vibration of the stator core and rotor field structures respectively from the other housing and shaft structure.

    摘要: A homopolar dynamoelectric machine is constructed with a magnetic field that is broken into segments along the axis of the machine. Liquid metal contacts are utilized to transmit electrical energy between the armature and current collecting members which have ducts for the transmission of cooling fluid located therein. Grouping armature conductors, and appropriately interconnecting the current collecting members to serially relate the voltages induced in the armature conductors in order to increase the magnitude of the output voltage, permits achievement of the desired output characteristics.

    摘要: A homopolar dynamoelectric machine is provided in which the magnetic fields are segmented circumferentially of the machine. Longitudinal field windings are placed in recesses in a cylindrical stator and energized so as to provide radial magnetic fields in polar regions between the field windings. Stator conductors are placed in slots in the polar regions. The rotor carries longitudinal conductors on its surface positioned to cut the radial magnetic fluxes, and current-collecting means are provided at both ends of the machine to make electrical contact with both ends of the rotor conductors. The current-collecting means are connected to the stator conductors to complete the electrical circuit of the machine.

    摘要: A unitary supporting structure for enclosing the superconducting field assembly of a dynamoelectric machine has a drive shaft portion for transmitting torque from a prime mover to the field assembly and a tubular portion integrally formed with the drive shaft portion. The tubular portion has a circumferentially extending outer wall which in combination with the drive shaft portion defines a chamber having a closed end with which the drive shaft portion is integrally formed and an opened end for receiving the field assembly. The field assembly is secured to the unitary supporting structure within the chamber in a cantilever mounting arrangement. The chamber is closed by means of an end plate to which a support shaft is affixed. The support shaft cooperates with the drive shaft portion to support the unitary structure for rotational movement within an annular stator member.

    摘要: A DC electromagnetic pump for circulating liquid-metal coolant through a nuclear reactor. The metal is circulated through ducts which are disposed in an annulus. Opposite walls of the ducts serve as electrodes to transmit current radially with respect to the annulus through the liquid metal in the ducts. The radial current is supplied by a homopolar generator. The walls of the ducts joining the electrodes are of composite structure. They include metal plates insulated from the electrodes backed up by insulators and are capable of withstanding the pressure of the liquid metal. These composite wall structures may also be of thin metal strips of low electrical conductivity backed up by sturdy insulators. A circumferential electric field is supplied to the liquid metal by a toroidal electromagnet which has core sections interposed between the ducts. The windings of the electromagnet extend over the ducts to suppress flux leakage. The windings are composed of metal which is superconductive at low temperatures and the electromagnet is maintained at a temperature at which it is superconductive. The liquid helium for maintaining the windings at superconductive temperature is fed through the conductor which supply the excitation for the electromagnet.

    摘要: Iron or other ferromagnetic material is utilized in the magnetic circuit of dynamoelectric machines having superconductive field or excitation windings. In DC machines, a stationary salient pole field structure with a superconductive main field winding is utilized. An armature winding is wound about a smooth rotor. In AC machines, a ferromagnetic structure that encloses and rotates with a superconductive excitation winding is utilized. The ferromagnetic structure may include either salient poles interconnected by ferromagnetic shunts or a slotted or toothed rotor.
