  "textContent": "The invention relates to a hysteresis motor-brake (170), comprising a rotating electric machine (17) with rotor (17a) and a stator (17b), and a power converter (18), electrically connecting the stator (17b) of said electric machine (17) to a DC link (19). In order to provide a high continuous braking power with very limited capacity of the power line it is proposed that - said stator (17b) comprises a core (172b) made of soft magnetic material and a plurality of coils (179a) connected to said power converter (18) with opportunity of forming a multi-pole rotatable magnetic field in a stator bore (171); - said rotor (17a) is concentrically arranged within a bore (171) of said stator (17b), and comprises a core (172a), made of hard magnetic material, and a shaft (173), connected to each other with capability of torque transfer; and - said rotor (17a) comprises at least one channel for cooling media with at least one inlet at a first shaft end (175a) and at least one outlet at a second shaft end (175b).",
