APPLICATION
The motors of 2SG3 450S-4 type are motors of special application and intended for driving mining machines
and equipment, especially for conveyors in collaboration with flow clutch assuring non-loaded start-up of the
drive.
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
" Induction 3-phase motors with squirrel-cage rotor,
" 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 the water jacket of body and channel in follower s disk

motor in version  B 1000V  50Hz (to 1100V/50Hz).
After settlement it is possible to execute the motors for other voltage in the a/m range and frequency of 60Hz.
" Class of insulation: class F or H,
" Thermal protection of motors: bimetal sensors (NC) or posistor PTC sensors -in winding and bearing nodes  two
identical circuits: basic and stand-by,
" Two-inlet terminal box with one or two cable inlets with rubber gaskets selected to the outer diameters of conductors,
type Wk3u/d... produced by Damel -Catalogue Card K4-15-136.
" The motor is equipped with the final link of protection conductor continuity control circuit, mounted in the terminal
box  primary execution: the final link CK-OA,
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 with frequency of 50Hz.
" The motors adapted for work in temperate climate; after settlement the adaptation for work in tropical climate TA or
TH is possible.

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 .
