摘要： The invention relates to a centrifuge (10), in particular a laboratory centrifuge, comprising a rotor (12) for receiving containers with material to be centrifuged, a drive shaft (14) on which the rotor (12) is supported, a motor (18) which drives the rotor (12) via the drive shaft, a bearing unit (30) with damping elements (36) each having a spring axis (36a), and a support element (54) for fixing the motor (18) in the centrifuge via the bearing unit (30), wherein the spring axes (36a) of the damping elements (36) are placed at an acute angle σ to the rotational axis Y of the motor (18). The invention is characterized in that the bearing unit (30) comprises a plurality of struts (34), preferably 3 to 21, which are connected to the damping elements (36), wherein the struts (34) are placed and arranged so that they are concentrically aligned with the respective spring axis.

摘要： The invention relates to a centrifuge (10), comprising a rotor (12), a drive shaft (14), on which the rotor (12) is supported, a motor (18), which drives the rotor (12) by means of the drive shaft (14), a supporting unit (30) having damping elements (36), each of which comprises a spring axis (36a), which supporting unit supports a rotational unit (19), which comprises the motor (18) together with the drive shaft (14) and the rotor (12), a sensor unit (82, 84) for sensing the rotational speed, a distance sensor (80) for determining imbalances of the rotational unit (19), which rotational unit rotates about an axis of rotation (14a), an acceleration sensor (88) for determining imbalances of the rotational unit (19), and a control and evaluation unit (90), which evaluates the data of the sensors (80, 82, 88), wherein the distance sensor (80) senses distance changes in an operative axis (36b). The invention is characterized in that the operative axis (36b) is oriented in relation to the axis of rotation (14a) in such a way that an angle between the operative axis (36b) and the axis of rotation (14a) of less than 90° including 0° results, at least in a projection onto a plane parallel to the operative axis (36b) and through the axis of rotation (14a).
