APPLICATION

One-speed motors of type 2SG3(2) mechanical value of 400 are intended for driving mining machines and
equipment , especially for driving 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.

•

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 channels in body and connected with it in series channel of
bearing disk P.

•

Form of execution : flanged execution – IM 3001(B5); arm - flanged execution – IM 2001(B3/B5); flange
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 – primary 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 Pt100 in winding and bearing nodes (execution against order).

•

Two-inlet terminal box equipped with one or two cable inlets with rubber gaskets selected to the outer
diameter of conductors , type Wk3u/d .. prod. 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: final unit CK-0A

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.
Motors executed in class of insulation H with reinforced wound insulation can be supplied from frequency
converters of class MSI (PWM) – the range of working frequency 0÷50Hz.

•

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

-

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

-

Certificate of Russian Testing Station МОС „Сертиум”, valid on the area of Russian Federation.
