Disclosed is a separator (1) comprising the following: a centrifugal drum (2) which has a vertical axis of rotation (D) and a supply pipe for a material that is to be centrifuged and processed; a drive spindle (3) for the centrifugal drum, said drive spindle (3) being rotatably mounted, by means of a bearing, in a housing (6) that is elastically supported on a machine frame (8); and a driving device with an electric driving motor (10) that encompasses a stator (11) and a motor rotor (12) which is aligned with the drive spindle (3). The driving device, including the motor housing (13), performs the same movements as the drive spindle (3) as a co-vibrating unit during operation. The disclosed separator (1) is characterized in that the driving device is connected to the machine frame (32) below the bearing, in particular at the lower axial end thereof, by means of at least one or more joint elements (31).
