APPLICATION  

The motors of type SG4W 562S-4, are intended for driving cutting units of combined cutters-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.  

CHARACTERISTIC FEATURES OF MOTORS 

•  The motors are 3 –phase induction motors with squirrel-cage rotors, 
•  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 motors SG4W 562S-4 are equipped with turn de – clutcher with torsional shaft (fig. 2). The torsional 

shaft is destroyed during violent locking of cutting unit and when destroyed it can be changed without 
disassembly of the motor from machine 

•  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: 1000; 1140V (Y) – 50Hz 

After settlement it is possible to execute the motors for other voltage up 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. 

•  Temperature control: thermometric resistors  Pt 100 in winding and bearing nodes,

 

•  Two–inlet, two-chamber terminal box, equipped with cable inlet Wk2u/d80... (production DAMEL) with 

rubber gasket and stopper Zk2u closing FLP not used cable inlet. Instead the stopper the cable inlet 
Wk2u/d47... (production DAMEL) with rubber gasket can be screwed down. 

• 

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.
