APPLICATION
Two-speed motors of type SG3 with mechanical value of 450 are intended for driving mining
machines and equipment, especially of 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
•
The induction 3-phase motors with squirrel-cage rotor, with two independent windings: for
synchronous speed 750 1/min – so called „slow speed ” (2p=8) and for synchronous speed
1500 1/min – so called „fast speed” (2p=4).
•
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 water jacket of body and connected in series
channel of bearing disk P.
•
Form of execution: flanged execution – IM 3001 (B5); flange FF740.
•
Basic voltage execution: 1000; 1140V (Y) – 50Hz
After settlement it is possible to execute the motors for other voltage and frequency of 60Hz.
•
Class of insulation: class H – with reinforced wound insulation,
•
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.
•
Three-inlet terminal box, can be equipped with two or three cable inlets:
− 2 cable inlets Wk3u/d … with rubber gaskets produced by Damel (Catalogue Card K4-15-136)
− cable inlet 54232…-M36 with rubber gasket produced by Gothe or stopper M36x1,5 closing
FLP inlet - instead of inlet 54232…-M36.
•
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,
• 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 standard).
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 Test Station МОС „Сертиум”, valid on the area of Russian Federation.
