Measuring method to determine the noise emission of an electric motor and measuring device |
| 摘要 |
A measuring method to determine the noise emission of an electric motor is proposed in which the vibrational excitation of the running electric motor is measured by a laser vibrometer device and this measured vibrational excitation is correlated with a noise level.
