APPLICATION

The one-speed motors of 2SG4 225S-4 and SG4 225M-4A are intended for driving mining machines and
equipment, and especially for driving transport conveyors and loader in 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 opearte the motors in the surroundings where the explosion-proof equipment is not required.

CHARACTERISTIC FEATURES OF MOTORS

•

Induction 3-phase motors with squirrel-cage rotor,

•

Explosion-proof construction with flame-proof casing of motor „d” and terminal box of reinforced construction “e”
- mark

I M2 EExde I to 1100V or explosion-proof construction with flame-proof casing of motor and terminal

box “d”- mark

I M2 EExde I to 1140V, equipment ranked as group I of category M2 according to Directive

94/9/EC,

•

The degree of protection IP 55 acc. to PN-EN 60034-5:2002U,

•

The motors are cooled by water flowing through the channels in body ,

•

The form of execution: special flanged execution – IM 3001(B5),

•

Basic voltage execution: 1000; 1140 V – 50 Hz

After settlement it is possible to execute the motors for other voltage and frequency of 60Hz.

•

Class of insulation: class H – primary execution, class H + reinforced wound insulation – execution against
order,

•

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

•

Single-inlet terminal box with one cable inlet with rubber gasket selected to the outer diameter of conductor of type
54235.2....or 54345.02 produced by Gothe,

•

The motor is equipped with the final link of protection conductor continuity control circuit, mounted in the
terminal box – primary execution: 8SX 9006-0AA00 (diode + resistor) produced by Bartec,

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,
- 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 (domestic norm).

CERTIFICATES

The motors have the certificates:

-

certificate EC ( ATEX ) issued by notified Testing Station FTZÚ,

valid on the area of European Union.
