The invention relates to a scroll compressor (10) and to a method for operating the scroll compressor (10). The scroll compressor (10) has a stator (15), an orbiter (20) which can be moved about an orbiter axis (55) relative to the stator (15), and a coupling device (50). The stator (15) and the orbiter (20) engage into each other and at least partly delimit at least one working area (105) for compressing a fluid (110) which can be filled into the working area (105). The coupling device (50) has a first coupling unit (60) which is arranged on the stator (15) and a second coupling unit (65) which is arranged on the orbiter (20) opposite the first coupling unit (60), wherein the first coupling unit (60) is magnetically coupled to the second coupling unit (65), and the second coupling unit (65) introduces a coupling torque (MK) which acts about the orbiter axis (55) into the orbiter (20).
