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.
•
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 external rotor built-in torque motors have degree of protection IP23.
