APPLICATION
The motor of SG3 400X-8/4 type is intended for driving belt conveyor and scraper belt conveyor.
The motor can be used in underground parts of mines and surface installations of the mines, where there
are possible explosion conditions for methane and/or coal dust.
CHARACTERISTIC FEATURES OF MOTOR

The motor is equipped with 2 (two) final links of protection conductor continuity control circuit [CK],
mounted in the terminal box – primary execution: the links CK-OA, produced by DAMEL
After settlement the assembly of final units CK… of other type is possible (e.g. diode+resistor, reverse
polarity, etc.) produced by DAMEL - catalogue card K4-15-121.
• The motor is intended for feeding from power network, start-up can be executed by:
– direct switching on the voltage at I or II speed,
– direct switching on the voltage at I speed and start-up at II speed through starter.
•
The motor is adapted for work in temperate climate; after settlement the adaptation for work in tropical
climate TA or TH is possible.
COMPATIBILITY WITH REQUIREMENTS OF STANDARDS
The motors meet requirements of Directive 94/9/EC (ATEX), European harmonized standards and
domestic norms:
- norms for electrical equipment in areas of explosion hazard:
-
EN 50014:1997+A1:1999+A2:1999 – Polish equivalent PN-EN 50014:2004,
-
EN 50018:2000+A1:2002 – Polish equivalent PN-EN 50018:2005,
-
EN 50019:2000 – Polish equivalent PN-EN 50019:2005,
- norms for rotational electric machines:
-
EN 60034-1:2004 – Polish equivalent PN-EN 60034-1:2005 (U),
- domestic norms for induction motors for mining machines:
PN G-38010:1997.
CERTIFICATES
The motor have the certificates:
-
certificate EU (ATEX ) issued by notified Testing Station GIG KD “BARBARA”,
valid on the area of European Union.
- decision of President of WUG (State Mining Authority) about permission for application in
underground mining plants.
