The present invention relates to a synchronous superconductive rotary machine with a superconductive rotor, a wind turbine, an assembly method and a repair method thereof. The rotor comprises a back iron connected to a thermally insulating support structure which is further connected to a base element. A coupling element is arranged on a peripheral surface of the base element for coupling to a matching coupling element located on a peripheral surface of a pole unit. The pole unit comprises a core element on which the coupling element is located and superconductive coils are wound on the core element. The pole unit is slid into position in an axial direction and fixed relative to the back iron by using fastening means. The base element, support structure and pole unit are wrapped in a thermal insulating laminate. This provides a simple and easy assembly and repair process that does require the rotor to be separated from the stator in order to replace a pole unit.

Synchronous superconductive rotary machine having a slidable pole assembly and methods thereof

A linear generator for power generation in a wave-driven power station is provided. The linear generator includes a primary part which has a plurality of annular primary coils, which are arranged concentrically with respect to an axis and are separated from one another by intermediate elements, and a secondary part which has a plurality of secondary coils, to which direct current can be applied. The secondary coils are arranged axially alongside one another with alternating polarity and have superconductor windings. The the arrangement of the primary coils in the primary part is in the form of an air-gap winding with intermediate elements composed of non-magnetizable material. The primary part or the secondary part is moved parallel to the axis, in an externally operated manner, by a buoy and the current which is induced in the primary coils by the relative movement between the primary part and the secondary part can be tapped off for power generation.

The invention relates to a primary part of a linear motor having a receptacle for a secondary part which can move along an axis in the receptacle, having a plurality of annular coils which are arranged coaxially with respect to the receptacle, and having a yoke, with teeth which are composed of a soft-magnetic material being arranged or formed between the end faces of adjacent coils. In order to provide a primary part or a linear motor which has a high power density in a compact form and allows good cooling with coolant, cooling gaps in which spacers are arranged are formed between the end faces of the coils and the teeth.

Primary part of a linear motor and linear motor therewith

The invention relates to a linear motor and in particular a primary part of the linear motor for the movement of a secondary part, with a plurality of coils for inducing a magnetic field transmitting force along an axis between the primary part and the secondary part and with teeth, which are made from a magnetizable material, are arranged between adjacent coils and have a base section remote from the axis and an end section facing the axis, the teeth on the end section being wider than on the base section. In order to provide a primary part or a linear motor which also allow for high force densities given a compact design, the coils also extend in the interspace between the end sections of adjacent teeth so as to increase the magnetic flux density.
