APPLICATION

The one –speed motors of SG4 562Y-4 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.

CHARACTERISTIC FEATURES OF MOTORS

•

Induction 3-phase motors with welded single 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 60034-5:2002U,

•

The motors are cooled by water flowing through the channels of body and bearing disks N and P,

•

The form of execution: special flanged execution – IM 4301,

•

Basic voltage execution: 3300V – 50Hz

After settlement it is possible to execute the motors for other voltage and frequency of 50/60Hz,
•

Class of insulation F or H,

•

Thermal protection of motors: bimetal sensors NC or posistor sensors PTC,

•

Thermometric resistors Pt100 are built in winding and bearings for temperature control,

•

Two-inlet terminal box with cable inlet Wk3u/d... produced by Damel for feeder cable and inlet 54232…- M36
produced by Gothe for conductor with auxiliary circuits,

•

The motor is equipped with the final link of protection conductor continuity control circuit, mounted in the
terminal box – primary execution: the final link CK-OA (with diode) produced by Damel,

•

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 and permissions:

-

certificate EC No KDB 04 ATEX 300X issued by notified Testing Station GIG KDB,
valid on the area of European Union.
