Abstract
A superconducting motor comprising a rotor, a stator on the outside of the rotor penetrated by an even number of holes, for each pair of holes, a coil comprising a U-shaped base and U-shaped sheets and made from a superconducting material, in which the sheets are fixed to one another and to the base, in which each column of a coil is inserted into one of the holes of the pair of holes.
Claims7
A superconducting motor comprising:
- a rotor with a rotor core carrying permanent magnets which is configured to rotate about a longitudinal axis;
- a stator arranged on an outside of the rotor and comprising a stator core made from a ferromagnetic material which has with an even number of holes distributed angularly and evenly about the rotor,
- for each pair of holes, a coil, each coil comprising:
- a U-shaped base with two first columns and a first bottom part fixed between the two first columns and
- a plurality of sheets, each in a U-shape, with two second columns and a second bottom part, made from a superconducting material, wherein the sheets are fixed on top of one another to form a stack, and wherein said stack is fixed to the U-shaped base by aligning each first column with second columns and the first bottom part with the second bottom parts,
- wherein each column of a coil is inserted into one of the holes of the pair of holes,
- wherein the U-shaped base is drilled with a channel with two openings, one opening exiting at an end of each first column, and
- wherein the openings are configured to be fluidically connected to a cooling circuit.

A method for manufacturing a coil comprising:
- additive manufacturing of a U-shaped base with two first columns and a first bottom part fixed between the two first columns, the U-shaped base being drilled with a channel with two openings, wherein one opening exits at an end of each first column, wherein the two openings are configured to be fluidically connected to a cooling circuit,
- providing a plurality of sheets made from a superconducting material,
- stacking said sheets from the plurality of sheets to form a stack,
- cutting said stack in such a manner as to give said sheets from the plurality of sheets a U-shape with two second columns forming legs of a U and a second bottom part, and
- attaching the stack to said U-shaped base by aligning each first column with second columns and the first bottom part with the second bottom parts.
