| 摘要 |
<p>The invention relates to an apparatus for recording a measured value inside the housing of a motor (1) or generator having a shaft (2) which is mounted such that it is electrically insulated from the housing (7) at least during rotation, wherein at least one first section of the shaft (2), which is situated inside the housing, is electrically conductively connected to a second section (3) of the shaft (2), which is arranged outside the housing (7). In order to make it possible to wirelessly transmit measured values from the inside of the housing of the motor (1) or generator to a receiver which is arranged outside the housing (7), it is proposed that the apparatus have a sensor (4) which is suitable for measuring the measured value, an injecting apparatus (5) for injecting a measurement signal, which is suitable for transmitting the measured value, into the first section of the shaft (2), and a radio receiver (6) for receiving the measurement signal, which is emitted by the second section (3) of the shaft (2), outside the housing (7).</p> |
