SG4 540L-4B i SG4B 540L-4B
APPLICATION
The motors of SG4 540L-4B and SG4B 540L-4B are intended for driving cutting units of combined cutter 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 SG4 540L-4B and SG4B 540L-4B motors are 3-phase induction 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/WE,
" Motors SG4 540L-4B have solid shaft with driver (moving link) with splines (Fig.2.1).
" Motors SG4B 540L-4B have hollow shaft with torsional shaft (Fig.2.2). The torsional shaft gets devastated during
violent locking of the getting unit, and when damaged it can be replaced without need for disassembly of motor from the
equipment.
" 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,
" Form of execution  flange execution,
" Primary voltage execution: 1000, 1140V (Y)  50Hz,
After settlement it is possible to execute the motors for other voltage 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 and bearing nodes  two
identical circuits: basic and stand-by,
" Thermometric resistors Pt100 are built in winding and bearing nodes for temperature control,
" Two-inlet, two-chamber terminal box equipped with inlet Wk2u/d80... (product of DAMEL) with rubber gasket and
stopper closing, not used as flame-proof protection, the orifice for cable inlet. The cable inlet 54232....-M36... (product
of GOETHE) can be screwed down instead of the stopper.
" 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 (DAMEL production .
After settlement there is possible to assemble the other type of link CK... (e.g. diode + resistor, reverse polarization,
etc.) product of 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/WE (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,
- 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:
PN G-38010:1997.
CERTIFICATES
The motors have the certificate WE (ATEX ) issued by notified Testing Station GIG KD  Barbara .
This certificate is valid on the area of European Union.
