Description
OPTIONS
6.8 - Particular conditions of use
- Thermal protections (§8)
- Heating resistors (§8)
- Surface temperatures:
As standard, the maximum temperature of our brake motors
is +125°C with a maximum ambient temperature ≤ +40°C.
Without derating the brake motor, the maximum surface
temperature shall be:
• +135°C if 40°C ≤ 50°C
• +145°C if 50°C ≤ 60°C
Caution: The motor's surface temperature during
operation requires wearing PPEs when handling
Qty
parts and during maintenance operations.

When detecting the following on the brake motor:
3 or 4
• abnormal noise or vibrations,
1
• abnormal heating on the bearing, check their condition.
Change damaged bearings as soon as possible to prevent
additional damage to the brake motor and driven devices.
When one bearing requires to be changed, also change the
other bearing. The floating bearing shall ensure expansion of
the rotor shaft (check its identification upon disassembly).
Always change the sealing gaskets when changing the
bearings.
- Sealing
After removing the bleeding plugs, refit them to ensure
the brake motor achieves the IP55 protection rating.
- Gaskets, bearings
