APPLICATION

The motors of type 3SG6 180M-4 are intended for driving mining machines and equipment, especially
driving unit 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

• Induction motors, 3-phase, with cast 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,

•

Basic voltage executions: 440, 500, 660, 1000, 1140V – 50Hz; after settlement it is possible to execute
the motors for other voltage up to 1140 V and frequency of 60Hz.

•

Class of insulation: class F,

•

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

•

One-inlet terminal box equipped with one cable inlet with rubber gasket selected to the outer diameter of
feeder cable , type Wk2/… or Wk2u/…. production DAMEL… –catalogue card K4-15-136,

•

The motors are equipped with the final link of protection conductor continuity control circuit, mounted in
the terminal box – primary execution: 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.

CERTIFICATES

The motors have the certificates:

- certificate EC ( ATEX ) issued by notified Testing Station GIG KD „BARBARA”, valid on the area of
European Union,
- certificate of Russian Testing Station MOC „Сертиум”, valid on the area of Russian Federation.
