Primary section
The primary sections satisfy the requirements for IP23 degree of protection in accordance with
EN 60529 and EN 60034‑5.
Secondary sections
The secondary sections are protected against corrosion to a large degree via structural
measures. Ensure that the air gap remains free of chips and other foreign bodies. Provide
suitable covers for this. From a distance of 150 mm from the surface of the secondary section,
hardly any more ferromagnetic particles are attracted.
Avoid using abrasive or corrosive substances (e.g. acids).
Installed motor
The better the motor installation space is protected against the ingress of foreign particles
(especially true for ferromagnetic particles), the longer the motor service life. The space around
the motor must be kept free of chips and other foreign bodies.
The degree of protection of the installed motor according to EN 60529 and EN 60034-5 is
primarily dictated by the machine construction, but must be at least IP23.
3.1.7
Vibration response
The vibration response of build-in motors in operation essentially depends on the machine
design and the application itself.
As a result of an unfavorable machine design, configuration or system settings, resonance
points can be excited, so that vibration severity level A according to EN 6003414 is not
reached.
Excessive vibration caused by resonance effects can frequently be avoided by
making suitable settings. You can obtain support on the topics of "Application"
and "Mechatronics" at Application & Mechatronic Support Direct Motors

3.1.8
Noise emissions
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
