Degree of protection

NOTICE
Damage to the motor caused by pollution
If the area where the motor is installed is polluted and dirty, then the motor can malfunction
and clog up.
• Keep the area where the motor is installed free of all dirt and pollution.
The machine construction surrounding the motor must fulfill degree of protection IP54 to
EN 60529 as a minimum.
The degree of protection for built-in motors is governed by the surrounding machine
construction. The better the motor installation space is protected against the ingress of
foreign particles (ferromagnetic particles), the longer the service life.
In particular, foreign particles in the air gap between the stator and rotor can destroy the
motor during operation.
This also applies to corrosive chemicals (e.g. coolants, oil) that could penetrate the motor
compartment. Corrosive chemicals can damage the magnetic bonds of the rotor.
Liquids can compromise the insulation resistance of the stator.
The thermal properties of the motor are influenced by the ingress of liquids and foreign
particles.
1FW6 torque motors have degree of protection IP23.
3.3

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. 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".
