APPLICATION  

The motors of  

SG4 540L-4, SG4B 540L-4, SG4 540L-4A and SG4B 540L-4A

  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. 

 

CHARACTERISTIC FEATURES OF MOTORS 

• The motors are 3-phase induction motors with squirrel-cage rotors,  

with power of:   150 kW – motors SG4(B) 540L-4  

170 kW – motors SG4(B) 540L-4A

• 

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/WE, 

• Motors SG4 540L-4 and SG4 540L-4A have soild shaft with driver (moving link) with splines (Fig.2.1). 
• Motors  SG4B 540L-4 and SG4B 540L-4A have hollow shaft with torsional shaft (Fig.2.2). The torsional shaft gets 

devastated during violent locking of the getting unit, and when damaged it can be replaced without need for 
disassembly of motor from the equipment. 

• The degree of protection IP 55 acc. to  PN EN 60034-5:2000U, 
• The motors are cooled by water – flowing through the water jacket of  body, 
• Form of execution – flange execution, 
• Primary 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 one and stand-by one, 

• Thermometric resistors Pt100 are built in  winding and bearings  for temperature control, 
• Two-inlet, two-chamber terminal box equipped with inlet Wk2u/d80... (product of DAMEL) with rubber gasket and 

stopper Zk2u which is closing, not used as flame-proof protection, the orifice for cable inlet. The cable inlet Wk2u/d47... 
(product of  DAMEL) with rubber gasket can be screwed down instead  of the stopper. 

• Motors are equipped with the final link of protection conductor  continuity control circuit, mounted  in the terminal box  –  

primary execution: the final link CK-OA (DAMEL               .  

 

After settlement there is possible to assemble the other type  of link  CK... (e.g. diode + resistor,   reverse  polarization, 
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/WE (ATEX), european harmonized standards and domestic standards: 
- standards 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, 

- standards for rotational electric machines: 

-  EN 60034-1:1998+A1:1998+A2:1999+AC:2000 – Polish equivalent  PN-EN 60034-1:2001  

- domestic standards for induction motors for mining machines: 

-    PN G-38010:1997.
