MINING INDUCTION MOTORS
2SG4 225S-4 i SG4 225M-4 PAGE 1/1
APPLICATION
The one-speed motors of 2SG4 225S-4 and SG4 225M-4A are intended for driving mining machines and
equipment, and especially for driving transport conveyors and loader in 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 opearte 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 and terminal box of reinforced construction  e

" The motors are cooled by water flowing through the channels in body ,
" The form of execution: special flanged execution  IM 3001(B5),
" Basic voltage execution: 1000; 1140 V  50 Hz
After settlement it is possible to execute the motors for other voltage and frequency of 60Hz.
" Class of insulation: class H  primary execution, class H + reinforced wound insulation  execution against
order,
" Thermal protection of motors: posistor PTC sensors in winding and bearing nodes  two identical circuits basic
and stand-by and bimetal sensors NC in winding  two circuits,
" Single-inlet terminal box with one cable inlet with rubber gasket selected to the outer diameter of conductor of type
54235.2....or 54345.02 produced by Gothe,
" The motor is equipped with the final link of protection conductor continuity control circuit, mounted in the
terminal box  primary execution: 8SX 9006-0AA00 (diode + resistor) produced by Bartec,
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,
- 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
