APPLICATION  

The motors of  3SG8 515M-4  type are motors intended for driving mining machines and equipment, 
especially for driving getting units of heading machines. 
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 

• 

Induction 3-phase motors with welded squirrel-cage rotor, 

• 

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 60034-5:2000U, 

• 

The motors are cooled by water flowing through the water jacket of body, 

• 

Primary voltage executions:  
1000, and 1140V – 50Hz; After settlement it is possible to execute the motors for other voltage up to  
1140V and frequency of 60Hz 

• 

Class of insulation: class H,  

• 

Thermal protection of motors: bimetal sensors (NC) or posistor PTC sensors -in winding of stator and in 
bearing nodes – two identical circuits: basic and stand-by, 

• 

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

• 

Two-inlet  terminal box equipped with one or two cable inlets with rubber gaskets selected to the outer 
diameters of conductors, type 54235.02…. and 54232… M28     produced by GOTHE&Co.  

• 

The motor is equipped with the final link of protection conductor  continuity control circuit, mounted in 
the terminal box  –  primary execution: the  link 8SX9006-0AA00 produced by BARTEC 

•  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 . 

CERTIFICATES 

The motors have the certificate EC (ATEX ) issued by notified Testing Station FTZÚ Radvanice, valid on 
the area of European Union.
