| 摘要 |
The invention relates to an apparatus for measuring moment data, especially torque data and/or rotational speed data and/or angle of rotation data of a device under test or a machine tool, comprising an electric machine (1), particularly a testing machine or a controlling machine, if necessary. The device under test or the machine tool is connected to the electric machine (1) with the aid of a shaft (3), optionally by interposing at least one coupling element. The shaft (3) of the electric machine (1) is provided with an encoded-magnetized measurement section (7) as an actuator in the vicinity of at least one of the bearings (4) thereof, said actuator being embodied as a magnetic field which is preferably magnetized according to defined parameters. At least one sensor, preferably at least two sensors, which detect/s the magnetic data of the magnetic field, is/are provided in the area of said measurement section (7). The sensor/s (8) is/are electrically or optically connected to an electronic preprocessing and processing unit (9), preferably in series. |
