APPLICATION
The motors of type 4SGKf 225L-4 are intended for driving mining machines and equipment, especially for
driving cutting unit of heading machines.
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 motor is executed as a set of two induction motors with squirrel-cage rotors operating on the same
shaft, supplied in parallel,
" 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 degree of protection IP 55 acc. to PN-EN 60034-5:2002U,
" The motors are cooled by water flowing through water jacket of body.
" Form of execution: flanged execution.
" Basic voltage execution: 380, 500, 550, 660, 1000; 1140V (Y)  50Hz
After settlement it is possible to execute the motors for other voltage in the range 380 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.
" One  inlet terminal box, equipped with cable inlet with rubber gasket,
" The motor is equipped with the final link of protection conductor continuity control circuit, mounted in the
terminal box  primary execution: final unit CK-0A 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:
PN G-38010:1997.
CERTIFICATES
The motors have the certificate EC (ATEX) issued by notified Testing Station GIG KD  BARBARA , valid on
the area of European Union.
