  • ELECTRIC MOTOR HAVING CRYOCOOLED ARMATURE LITZ WINDINGS
    Publication number: 20260180405
    Abstract: A cryocooled electric motor (500) comprising: a stator (510) comprising a magnetic core (510,510a), a rotor (520), an armature arrangement (550) and a cryogen source arranged to provide a cryonic fluid (544) to the armature arrangement (550), in order to cool the armature arrangement (550) below a temperature of 77 K, wherein the armature arrangement (550) comprises a plurality of Litz wires (552) and wherein the armature arrangement (550) is able to provide during operation of the motor a current density of more than 25 A/mm2.

  • ELECTRIC MACHINE
    Publication number: 20220037979
    Abstract: An electric machine including a stator having a fully non-magnetic core and stator windings formed of a non-superconducting transposed conductor to reduce eddy current losses. It further includes a rotor having a fully non-magnetic core and superconducting windings or superconducting magnets which produce a magnetic field for interaction with the stator windings. A cryogenic cooling system is arranged to cool the stator windings to reduce conduction losses in the stator windings.
