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.
