APPLICATION
The motors of SG6 570M-4 and SG6 570M-4A type are intended for driving cutter units of combined cutters
loaders.
The motors 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.
There is also possible to operate the motors in the surroundings where the explosion-proof equipment is not
required.
CHARACTERISTIC FEATURES OF MOTORS
" The motors of SG6 570M-4 and SG6 570M-4A type are induction 3-phase motors with squirrel-cage
rotors,
" Explosion-proof construction with flame-proof casing of motor  d - mark I M2 EExd I, equipment
ranked as group I of category M2 according to Directive 94/9/EC,
" The motors of SG6 570M-4 and SG6 570M-4A type have solid shaft with driving shaft neck with
splines.
" The degree of protection IP 55 acc. to PN-EN 60034-5:2000U,
" The motors are cooled by water flowing through the water jacket of body,
" Forms of execution - flanged execution
" Basic voltage execution: 500; 660; 1000; 1140 V (refers to SG6 570M-4) and 1000; 1140 V (refers to SG6
570M-4A)  connection (Y)- 50Hz.
After settlement it is possible to execute the motors for other voltage up to 1140V and frequency of
60Hz.
" Class of insulation: class F- primary execution, class H  execution against order,
" Thermal protection of motors: bimetal sensors (NC) or posistor PTC sensors -in winding of stator and
bearing nodes  two identical circuits: basic and stand-by,
" Temperature control: thermometric resistors Pt 100 in winding and bearing nodes,
" Two-inlet, two-chamber terminal box equipped with one cable inlet Wk2u/d80.. (production DAMEL) with
rubber gasket and stopper Zk2u closing FLP unused orifice for cable inlet. Instead of the stopper the
cable inlet of Wk2u/d47 (produced by DAMEL) can be screwed down with rubber gasket.
" The motors are equipped with the final link of protection conductor continuity control circuit, mounted in
the terminal box  primary execution: the final link CK-OA, produced by DAMEL
After settlement the assembly of final unit CK of other type is possible (e.g. diode + resistor, reverse
polarity, etc.) produced by DAMEL catalogue card K4-15-121.
" Feeding and start-up: the motors are intended for feeding from power network  start-up by direct
switching on the voltage.
" The motors 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 50014:2002U,
- EN 50018:2000+A1:2002  Polish equivalent PN-EN 50018:2002U + A1: 2003U,
- EN 50019:2000  Polish equivalent PN-EN 50019:2002U,
- norms for rotational electric machines:
- EN 60034-1:1998+A1:1998+A2:1999+AC:2000  Polish equivalent PN-EN 60034-1:2001
- domestic norms for induction motors for mining machines:
