Noise emission

Hearing damage
Hearing damage may occur if the motor exceeds a sound pressure level of 70 dB (A) due to the
type of mounting or pulse frequency.
• Reduce the sound pressure level by implementing sound damping and/or soundproofing
The following components and settings influence the noise levels reached when built-in motors
are operational:
• Machine design
• Encoder system
• Bearing
• Controller settings
• Pulse frequency
As a result of unfavorable machine designs, configuration or system settings, measuring
surface sound pressure levels of over 70dB (A) can occur. Contact Application & Mechatronic
Support Direct Motors if you require help in applying remedial measures. You can find
contact data in the Introduction under "Technical Support".
