APPLICATION

The one-speed motors of 3SG8 420M-4 type are motors intended for driving mining machines and
equipment, especially for driving getting unit of heading machines.
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 welded 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 water jacket of body,

•

The form of execution: special flanged execution –IM3201,

•

Primary voltage executions:
380; 500; 550; 660; 1000; 1140V – 50Hz;
After settlement it is possible to execute the motors for other voltage and frequency of 50/60Hz

•

Class of insulation: class H – primary execution, class H reinforced by wound insulation –
execution against order,

•

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

•

One-inlet terminal box equipped with one or two cable inlets with rubber gaskets selected to the
outer diameters of conductors, type 54235.2…. and 54345.02…produced by GOTHE&Co.

•

The motor is equipped with the final link of protection conductor continuity control circuit, mounted
in the terminal box – primary execution: the link 8SX9006-0AA00 (diode + resistor) produced by
BARTEC

• 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) .
