MGM
MGM brake motors come with standard IP54 enclosure rating. On request, motors can be provided with IP55 or IP56 enclosure
rating. For use in standard industrial environments IP54 is sufficient. For outdoor applications or for application that involve contact
with water, protection degree IP55 or IP56 is advisable. It’s always advisable to protect the motor as much as possible.
During the installation stage secure the proper tightening of the cable gland and the insertion of the wire from the bottom upwards.
On request, for outdoor vertical mounting with shaft down, a rain roof (BM series) or a special brake cover (BA series) are available
MGM motors are also available with special corrosion protection for hard environment application such as marine application
and tough processing applications in poultry, meat, dairy, snack foods and pharmaceuticals. On request motors can be provided
with the following option:
• Bearings for high/low temperatures
• Oil seal on drive shaft end
• Special frame/plates corrosion-resistant surface treatment and/or epoxy painting
• Drain holes
• Stainless steel nameplate
• Stainless steel shaft-end
• Stainless steel or zinc plated brake friction surface
• Stainless steel nuts, bolts, tie rods and screws
Contact MGM for additional information.

The enclosure rating of the motor has to be suitable to the environment conditions the motor operates in. According to the
IEC34-5 (EN 60034-5) standard the designation of the protection degree is expressed by means of a symbol made up of two
letters (IP) followed by a two digit number. The first digit indicates the protection degree provided by the motor enclosure in
contact with parts in motion, electrically energized, or against the penetration of foreign bodies. The second digit indicates
the protection degree of the motor enclosure against damages caused by the penetration of liquids.
GENERAL CHARACTERISTICS
Enclosure Rating (Protection Degree)
0
No protection.
1
The machine is protected against the penetration of solid
bodies greater than 50 mm in diameter (for example, protection
against the accidental touch of a hand).
2
The machine is protected against the penetration of
solidbodies greater than 12 mm in diameter.
3
The machine is protected against the penetration of solid
bodies greater than 2.5 mm in diameter.
4
The machine is protected against the penetration of solid
bodies greater than 1mm in diameter.
5
The machine is protected against the penetration of dust.
The penetration is not completely avoided, but should not
compromise the good functioning of the machine.
6
Dust tight machine
0
No protection.
1
Vertical dropping of water on the machine will not result in
damaging effects.
2
Vertical dropping of water on the machine will not result in
damaging effects when the machine is not inclined more than
15
°
from its normal position.
3
Water or rain dropping on the machine at an angle up to
60
°
will not result in damaging effects.
4
Water spraying on the machine from any angle will not
result in damaging effects to the machine.
5
Water jets on the machine from any angle will not result in
damaging effects to the machine.
6
Waves of water will not result in damaging effects to the
machine.
7
Immersing the machine in water under specific conditions
of pressure and time will not cause the ingress of a damaging
quantity of water.
8
Immersing the machine permanently in water under
conditions of pressure and time given by the manufacturer will
not result in damaging effects.
