APPLICATION
Two-speed motors of type 2SGS of mechanical quantity 355 and 400 are intended for driving machines and
mining equipment, especially belt conveyors and scraper belt conveyors.
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
" Motors of type 2SGS are induction 3-phase motors with squirrel-cage rotor, with two independent
windings for synchronous speed 500 min-1  so called  slow speed (2p=12) and for synchronous speed
1500 1/min  so called  fast speed (2p=4).
" 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 channels in body and connected in series channel of
bearing disks P,
" The form of execution: flanged execution  IM 3001 (B5);flange FF740.
" Basic voltage execution: 1000; 1140V  50Hz
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: bimetal sensors NC and posistor sensors PTC in winding and bearing nodes 
two identical circuits: primary and stand-by,
" Temperature control: Thermometric resistors Pt100 are built in winding and bearings for temperature
control (execution against order),
" Two-inlet terminal box equipped with one or two cable inlets with rubber gaskets selected to the outer diameters
of conductors of type Wk3u/d .. prod. DAMEL (Catalogue Card K4-15-136), or two connection sockets of
VICTOR Company.
" 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,
" 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
- domestic norms for induction motors for mining machines:
- PN G-38010:1997 (domestic norm).
