APPLICATION
The motor of type SG3 450Y-8/4 is intended for driving belt conveyor or scraper belt conveyor.
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

• Two-speed 3-phase induction motor with rod double squirrel - cage soldered to rings.
• 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 60034-5:2000U,
• The motors are cooled by water flowing through water jacket of body and disk P.
• The motor has got solid shaft.
• Primary voltage execution: 3300V 50 Hz.
• Class of insulation: class H.
•

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.
• Three –inlet terminal box, equipped with:

– two cable inlets with rubber gasket selected to the outer diameter of the feeder cable, type Wk3u/....

production DAMEL – catalogue card K4-15-136 or 1 cable inlet of type Wk3u/... and stopper Zk3u,

– one cable inlet of type 54232...-M28 production Goethe or stopper M28x1,5.

• The motor is executed as flanged with centring lock on disk N Ø680h8. The motor is fixed on the

machine through the centring flange by using 8 screws M24. Overall and assembly dimensions of the
motor are presented on drwg. 2a and 2b.

•

The motor is equipped with two final links of protection conductor continuity control circuit, mounted in the terminal

box – primary execution: final unit CK-0A produced by DAMEL

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).

• The motor is intended for feeding from the mains, start-up can be executed:

−

by direct switching on the voltage

on I or II speed,

−

by direct switching on the voltage

on I speed and start-up on II speed through starter.

•

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 + A1:2003U,

EN 50019:2000 – Polish equivalent PN-EN 50019:2002U,

− norms for rotational electric machines:

EN 60034-1:1998+A1:1998+A2:1999+A11:2002 – Polish equivalent PN-EN 60034-1:2001 +
A11:2003,

− domestic norms for induction motors for mining machines:

PN G-38010:1997.
