摘要： A method for integrally manufacturing a stator core and a housing for an electrical machine includes printing, by a three-dimensional (3D) printing process, the stator core. In addition, the method includes printing, by the 3D printing process, the housing. In particular, printing the housing occurs contemporaneously with printing the stator core. The method also includes printing, by the 3D printing process, at least one end cap and coupling the at least one end cap to the housing to enclose a cavity defined by the housing.

摘要： Provided are a rotor core, a method for cooling a rotor core, and a superconducting rotating machine, capable of effectively and uniformly cooling superconducting coils without causing cold brittleness in an extremely low temperature. The rotor core 10, which is made of a substantially hollow cylindrical member of nonmagnetic material, has a cylindrical cavity 13 defined therein and extending in the longitudinal axis of the member. Helium gas 300 is delivered in the rotor core 10 from the proximal to distal sides and vice versa, which ensures a uniform cooling of the rotor core 10. This also ensures a uniform and effective cooling of the superconducting coils.

摘要： A stator arrangement particularly suitable for use in an air-cooled generator or other such electric machine includes a stator with an outer stator surface, an opening therein defining an inner stator surface, and longitudinally opposed stator end surfaces. Conductive coils are supported by the stator, and include end turns overlying the longitudinally opposed stator end surfaces. In order to block out environmental contaminants and prevent conductive coil shorting, protective barriers are mounted over the end turns and secured to the stator.
