SG3W 760Y-4 PAGE 1/1
APPLICATION
The one  speed motors of SG3W 760Y-4 type are intended for driving mining machines and equipment, and
especially for driving getting 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.

" The form of execution: special flanged execution  IM 3301,
" Basic voltage execution: 3300V  50Hz
After settlement it is possible to execute the motors for other voltage and frequency of 50/60Hz,
" Class of insulation F  primary execution, class H  execution against order,
" Thermal protection of motors: bimetal sensors NC and posistor sensors PTC in winding and bearing nodes 
two identical circuits: primary and stand-by,
" Thermometric resistors Pt100 are built in winding and bearings for temperature control,
" Two-inlet terminal box with cable inlet Wk3u/d... produced by Damel for feeder cable and inlet 54232& - M36
produced by Gothe for conductor with auxiliary circuits,
" 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 (with diode) produced by Damel,
" 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 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 (domestic norm).
