APPLICATION

The two-speed motors of 2SGS type and mechanical series of 355 are intended for driving mining machines and
equipment, especially for belt conveyors and scraper belt conveyors.
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 squirrel-cage rotor, with two independent windings: for synchronous speed of
750 r.p.m. – so called “slow speed” (2p=8) and for synchronous speed of 1500 r.p.m. – so called “fast speed”
(2p=4).

•

Explosion-proof construction with flame-proof casing of motor “d” - mark

I M2 Exd I, equipment ranked

as group I of category M2 according to Directive 94/9/CE.

•

Degree of protection IP 55 acc. to PN-EN 60034-5:2004.

•

The motors are cooled by water flowing through the water channels in body and a channel of bearing’s disk
P connected in series with the body.

•

Form of execution: flanged execution – IM 3001 (B5); flanged FF740.

•

Basic voltage execution: 1000; 1140V – 50Hz .

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

•

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

•

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

•

Temperature control: thermometric resistors Pt 100 in winding and bearing nodes (execution against order).

•

Two-inlet terminal box with one or two cable inlets with rubber gaskets selected to the outer diameters of
conductors, type Wk3u/d... produced by DAMEL (Catalogue Card K4-15-136).

•

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.

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 the 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/CE (ATEX), European harmonized norms and domestic norms:

- norms for electrical equipment in areas of explosion hazard:

-

EN 60079-0:2004 – Polish equivalent PN-EN 60079-0:2004(U),

-

EN 60079-1:2004 – Polish equivalent PN- EN 60079-1:2004(U),

-

EN 60079-7:2003 – Polish equivalent PN-EN 60079-7:2004(U),

- norms for rotational electric machines:

-

EN 60034-1:2004 – Polish equivalent PN-EN 60034-1:2005(U)

-

domestic norms for induction motors for mining machines:

-

PN G-38010:1997 (domestic norm).

CERTIFICATES

The motors have the certificates:

-

certificate CE (ATEX) issued by notified Testing Station GIG KD “BARBARA”, valid on the area of
European Union.
